calculate the density (in g/l) of xe at 61 °c and 598 mmhg. (r = 0.08206 l·atm/mol·k)

Answers

Answer 1

The density of xenon (Xe) at 61 °C and 598 mmHg is 14.38 g/L.

The ideal gas equation can be used to calculate the density of xenon (Xe) at a given temperature and pressure. To begin, let's define the variables.P = 598 mmHgT = 61 °CR = 0.08206 L · atm/mol ·KAtomic weight of Xe = 131.3

To calculate the density of Xe, we must first convert the given pressure and temperature into standard units. The temperature must be in kelvin and the pressure must be in atmospheres (atm).So, T = 61 + 273.15 = 334.15 K and P = 598/760 = 0.7868 atm.Using the ideal gas equation PV = nRT, we can calculate the number of moles of Xe present: (0.7868 atm) × V = n × (0.08206 L · atm/mol · K) × (334.15 K)n

= (0.7868 V) / (27.011 × 0.08206 × 334.15) = (0.7868 V) / 7.15

The atomic weight of xenon (Xe) is 131.3 g/mol.

Therefore, the mass of Xe in grams is:m = 131.3 g/mol × n = 131.3 g/mol × [(0.7868 V) / 7.15] = 14.38 V g

Dividing the mass by the volume gives us the density in g/L:

Density of Xe = m / V = (14.38 V g) / V = 14.38 g/L

The density of xenon (Xe) at 61 °C and 598 mmHg is 14.38 g/L.

to separate a mixture of p-toluidine and p-nitrotoluene dissolved in ether,extract the ether solution with aqueous hcl and treat the water layer with aqueous naoh. true

Answers

The answer to the given question is given as follows:

given question talks about separating a mixture of p-toluidine and p-nitrotoluene dissolved in ether. To separate this mixture, we need to extract the ether solution with aqueous HCl and then treat the water layer with aqueous NaOH.

Now, we will discuss each step of this process in detail:

Step 1: Extraction of Ether Solution with Aqueous HCl

In this step, we are going to extract the ether solution with aqueous HCl. This step is carried out to convert p-nitrotoluene into p-nitrotoluene acid. The basic principle of this step is that p-toluidine is a base and p-nitrotoluene is a neutral compound. Therefore, when we add HCl, it will protonate p-toluidine, and it will form an ion that will be extracted in the aqueous phase. Whereas, p-nitrotoluene will remain in the organic phase. The resulting mixture will contain an aqueous layer and an organic layer. The organic layer is of our interest as it contains the compound that we are going to extract.

Step 2: Treatment of the Water Layer with Aqueous NaOH

In this step, we are going to treat the water layer with aqueous NaOH. This step is carried out to convert p-nitrotoluene acid into p-nitrotoluene. The basic principle of this step is that p-nitrotoluene acid is an acid, and when we add NaOH, it will react with p-nitrotoluene acid and convert it into p-nitrotoluene.

This reaction is given below:

p-nitrotoluene acid + NaOH → p-nitrotoluene + NaNO2 + H2O

This reaction takes place only in the aqueous phase as both the reactants are present in the aqueous layer. So, the resulting mixture will contain an aqueous layer and an organic layer. The organic layer is of our interest as it contains the compound that we are going to extract.

Step 3: Final Extraction of Organic Layer

In this step, we are going to extract the organic layer from the mixture. The organic layer contains the compound that we are going to extract. So, we can evaporate the solvent, and we will get the desired compound that is p-nitrotoluene. Hence, the final product of this process will be p-nitrotoluene.

which of the following gas samples would be most likely to behave ideally under the stated condition? A) H2 at 400atm and 25 C degree, b) CO at 200atm and 25 C degree, c) Ar at STP, d) N2 at atm and -70 C degree, e) SO2 at 2 atm and 0 K. Please, answer with detail explain.

Answers

In chemistry, the ideal gas law is a simple equation that specifies how the physical properties of an ideal gas change as pressure, volume, and temperature are changed. It can be utilized to assess the behavior of a gas under various conditions.

Given conditions in the question, the Ar gas sample at STP (Standard Temperature and Pressure) is most likely to behave ideally. The reason behind this statement is explained below: STP (Standard Temperature and Pressure) is defined as 273 K (0°C) and 1 atm of pressure.

According to the ideal gas law, a gas will act ideally under the given condition if the intermolecular forces between the gas particles are negligible. Intermolecular forces are defined as the forces of attraction between two or more particles. The Ar gas is a noble gas, and as such, it has weak intermolecular forces. The weak intermolecular forces between the Ar gas particles make it an ideal gas under STP conditions. Additionally, Ar gas consists of a single atom and has a zero molecular weight. Hence, it has no volume, which makes it an ideal gas under STP conditions.

Therefore, the Ar gas sample at STP is most likely to behave ideally under the stated condition. The other options, H2 at 400atm and 25 C degree, CO at 200atm and 25 C degree, N2 at atm and -70 C degree, and SO2 at 2 atm and 0 K, have various pressures and temperatures that deviate from the standard conditions, and they may have strong intermolecular forces that make them non-ideal gases.

which of the following is the stronger brønsted-lowry acid, hclo3 or hclo2?

Answers

HClO3 is the stronger Brønsted-Lowry acid between the two compounds.

In the Brønsted-Lowry acid-base theory, an acid is defined as a substance that donates a proton (H+) and a base is a substance that accepts a proton. To determine which of the two acids, HClO3 or HClO2, is stronger, we need to assess their ability to donate a proton.

HClO3, also known as chloric acid, has a central chlorine atom bonded to three oxygen atoms and one hydrogen atom. The presence of three electronegative oxygen atoms surrounding the central chlorine atom increases the acidity of HClO3. The oxygen atoms withdraw electron density from the chlorine atom, making it more willing to donate a proton, thus making HClO3 a stronger acid.

HClO2, also known as chlorous acid, has a similar structure with a central chlorine atom bonded to two oxygen atoms and one hydrogen atom. Compared to HClO3, HClO2 has fewer electronegative oxygen atoms surrounding the central chlorine atom. This reduced electron withdrawal decreases the acidity of HClO2, making it a weaker acid compared to HClO3.

Therefore, HClO3 is the stronger Brønsted-Lowry acid between the two compounds.

Answers

There are 4,000 parts per million (ppm) of chlorine in the pool.

To calculate the parts per million (ppm) of chlorine in the pool, we can use the formula:

ppm = (part / whole) x 1,000,000

In this case, the part is the amount of chlorine, which is given as 8 g, and the whole is the amount of water, which is 2,000,000 g. Substituting these values into the formula, we get:

ppm = (8 g / 2,000,000 g) x 1,000,000

Simplifying this expression, we find:

ppm = (4 x 10^-6) x 1,000,000

ppm = 4,000

This means that for every one million parts of the pool's water, there are 4,000 parts of chlorine. In other words, the concentration of chlorine in the pool is 4,000 ppm, indicating a relatively high level of chlorine compared to the water.

draw the structure of an alkyl halide that could be used in an e2 reaction

Answers

An alkyl halide that can undergo an E2 (elimination) reaction typically has a primary or secondary carbon bonded to a halogen atom. Here's an example of structure attached.

In this structure, R represents an alkyl group (such as methyl, ethyl, propyl, etc.), X represents a halogen atom (such as Cl, Br, or I), and the hydrogen atoms attached to the carbon atom labeled as C can be different alkyl groups or hydrogens.

In an E2 reaction, the alkyl halide acts as the substrate and undergoes a bimolecular elimination. During the reaction, a base abstracts a proton from a beta-carbon (carbon adjacent to the carbon with the halogen atom), and simultaneously, the leaving group (halogen) is expelled, resulting in the formation of a double bond.

The reaction proceeds more readily with primary or secondary alkyl halides due to the availability of beta-hydrogens, which are required for the elimination process. Tertiary alkyl halides are generally unreactive in E2 reactions because the steric hindrance around the carbon atom hinders the approach of the base.

how can you tell if a chemical equation represents hydrolysis

Answers

To identify hydrolysis in a chemical equation, check for the presence of water as a reactant and the splitting of a compound into two or more components.

Hydrolysis is a chemical reaction in which water molecules are added to a compound, resulting in the splitting of the compound into two or more products. In order to identify whether a chemical equation represents hydrolysis, there are two key factors to consider.

Firstly, look for the presence of water (H2O) as a reactant in the equation. Hydrolysis reactions require water to provide the necessary hydroxide ions (OH-) for the reaction to occur. Therefore, if water is listed as one of the reactants, it is an indication that hydrolysis might be taking place.

Secondly, observe whether the compound undergoing the reaction is being split into two or more components. Hydrolysis typically involves the breaking of chemical bonds within a compound, resulting in the formation of new compounds or ions. The addition of water molecules to the compound facilitates this splitting process. If the equation shows the formation of multiple products from a single reactant, it suggests hydrolysis is occurring.

the permanent electric dipole moment of the water molecule (h2o) is 6.2×10−30c⋅m .

Answers

The permanent electric dipole moment of the water molecule (H2O) is 6.2×10^−30 C⋅m.

The electric dipole moment is the distance between two equal but opposite charges.

The electric dipole moment for H2O is 6.2 x 10^-30 C⋅m. In general, the electric dipole moment is defined as the product of charge and distance between the charges.The water molecule is polar because of its bent structure and electronegativity.

A permanent dipole is created as a result of the electronegativity difference between hydrogen and oxygen.

Because of the differences in the electronegativity of the atoms, electrons are drawn toward the oxygen atom, generating a negative charge, whereas the hydrogen atoms develop a positive charge as a result of the electron migration, resulting in a net dipole moment of the H2O molecule.

Summary:The water molecule's permanent electric dipole moment is 6.2×10^-30 C⋅m. The dipole moment is created as a result of the polar nature of the molecule, which is caused by differences in electronegativity between the atoms.

solid nickel reacts with aqueous lead (ii) nitrate to form solid lead. what is the net ionic equation for this reaction?

Answers

The chemical equation for this reaction is:

Ni(s) + Pb(NO3)2(aq) → Pb(s) + Ni(NO3)2(aq)

The ionic equation for this reaction is:

Ni(s) + Pb2+(aq) + 2 NO3-(aq) → Pb(s) + Ni2+(aq) + 2 NO3-(aq)

The net ionic equation can be obtained by canceling the spectator ions (the ions that appear on both sides of the equation and do not participate in the reaction):

Ni(s) + Pb2+(aq) → Pb(s) + Ni2+(aq)

So, the net ionic equation for this reaction is:

Ni(s) + Pb2+(aq) → Pb(s) + Ni2+(aq)

Goodluck!

The net ionic equation for the reaction between solid nickel and aqueous lead (II) nitrate is: Ni(s) + Pb2+(aq) → Pb(s) + Ni2+(aq)

Explanation: The net ionic equation involves the reactants that are involved in the reaction, as well as the products formed. The term "net" means that the spectator ions are removed from the equation.

Nickel is a solid and, therefore, has no charge. It does not dissolve in the aqueous solution and is written in its solid state. Lead (II) nitrate is dissolved in water to form lead ions and nitrate ions.

The molecular equation for the reaction is: Ni(s) + Pb(NO3)2(aq) → Pb(s) + Ni(NO3)2(aq)

To obtain the net ionic equation, the spectator ions are removed from the above equation. The nitrate ion is a spectator ion, and it does not participate in the reaction.Ni(s) + Pb2+(aq) → Pb(s) + Ni2+(aq)

Therefore, the net ionic equation for the reaction between solid nickel and aqueous lead (II) nitrate is Ni(s) + Pb2+(aq) → Pb(s) + Ni2+(aq).

the kp for the reaction below is 1.49 × 108 at 100.0°c: co(g) cl2(g) → cocl2(g)

Answers

The value of Kp for the given reaction: co(g) + cl2(g) → cocl2(g) at 100.0° C is 1.49 × 10⁸. Now we need to find the value of Kc at the same temperature.

We know that Kp = Kc(RT)^Δng, where Δng is the change in the number of moles of gaseous products minus the number of moles of gaseous reactants.Here, Δng = 1 - 2 = -1 as we have one gaseous reactant and two gaseous products. R is the ideal gas constant, T is the temperature, and Kp is the equilibrium constant in terms of pressure, and Kc is the equilibrium constant in terms of concentration, thus;Kp = Kc(RT)^Δng1.49 × 10⁸ = Kc(RT)^-1Taking natural logs on both sides;ln 1.49 × 10⁸ = ln Kc + (-1) ln RTln 1.49 × 10⁸ = ln Kc - ln RT1.49 × 10⁸/RT = KcThis is the main answer where we have found the value of Kc. Let's move on to the explanation:The value of Kp at 100°C is 1.49 × 10⁸. We can use the equation Kp = Kc(RT)^Δng to find the value of Kc, where Δng is the change in the number of moles of gaseous products minus the number of moles of gaseous reactants, R is the ideal gas constant, T is the temperature, and Kp and Kc are the equilibrium constants in terms of pressure and concentration respectively.We can calculate the value of Kc by rearranging the equation as follows: Kc = Kp/(RT)^Δng.

Substituting the given values, we get;Kc = 1.49 × 10⁸/(8.314 J K⁻¹ mol⁻¹ × 373.15 K)^(-1) = 1.41 × 10⁵ M⁻¹The summary of the answer is that the value of Kc at 100.0°C is 1.41 × 10⁵ M⁻¹.

hydrogen can be prepared by suitable electrolysis of aqueous sodium salts. true or false?

Answers

False.

hydrogen can not be prepared by suitable electrolysis of aqueous sodium salts.

Hydrogen gas (H₂) can be prepared by the electrolysis of water, not aqueous sodium salts. During the process of electrolysis of water, the water molecule (H₂O) is split into hydrogen gas (H₂) and oxygen gas (O₂) using an electric current. This process occurs in an electrolytic cell with two electrodes, where hydrogen gas is produced at the cathode and oxygen gas is produced at the anode.

The electrolysis of aqueous sodium salts typically results in the production of sodium hydroxide (NaOH) or sodium metal (Na) at the cathode, depending on the specific conditions and electrolyte used. Hydrogen gas is not typically produced as a direct product of the electrolysis of aqueous sodium salts.

Could you determine the density of cadmium nitrate usingwater?
I think this may be an easy question that I am overthinking. Cadmium nitrate has a melting point of 59 C so itis liquid and it is water soluble. I think you would normalynot use water to determine it's density...instead use a pipet andflask to do the measurements. However, that doesn't mean youcouldn't measure it's density by way of water displacement,right? So, my thinking is yes. Or am I missing somepoint?
Thanks.

Answers

Using water displacement can be a viable method to determine the density of cadmium nitrate.

While it is not a conventional method, water displacement can be used to determine the density of cadmium nitrate. By measuring the volume of a known mass of cadmium nitrate based on the amount of water it displaces, the density can be calculated.

However, it is important to consider the solubility of cadmium nitrate in water and any potential chemical reactions or interactions that may occur. This method can provide an estimation of the density, but it is essential to exercise caution and consider the limitations and potential factors that may affect the accuracy of the measurement.
