how many grams of hcl would be produced if 54 grams of water were used

Answer:

The temperature is "298.51 K".

Explanation:

The given values are:

Density of ammonia,

d = 0.812 g/L

Pressure,

P = 1.17 atm

Mass:

M = [tex]NH_3[/tex]

   = [tex]14+ 1\times 3[/tex]

   = [tex]17[/tex]

As we know,

⇒ [tex]PV=nRT[/tex]

∴  [tex]T=\frac{PV}{nR}[/tex]

       [tex]=\frac{PV}{\frac{W}{M}\times R }[/tex]

       [tex]=\frac{PVM}{W\times R}[/tex]

By putting the value of "W", get

       [tex]=\frac{PVM}{V\times d\times R}[/tex]

       [tex]=\frac{P\times M}{d\times R}[/tex]

On substituting the values in the above equation, we get

       [tex]=\frac{1.17\times 17}{0.812\times 0.08205}[/tex]

       [tex]=\frac{19.89}{0.06699}[/tex]

       [tex]=298.51 \ K[/tex]

Answer:

The reactionnis known as a decomposition reaction

The equation of the reaction is given below as:

H₂CO₃ -----> H₂O + CO₂

Explanation:

A reaction in which a single compound is split into two or more simpler substances is known as a decomposition reaction.

In the reaction in which when a soda can is opened and left to the environment, the fizz in the soda, carbonic acid, separates into water and carbon dioxide is an example of a decomposition reaction.

The equation of the reaction is given below:

H₂CO₃ -----> H₂O + CO₂

In the reaction above, a larger molecular weight compound, carbonic acid with the molecular, H₂CO₃ is splits into two simpler substances of smaller molecular weight, water, H₂O and carbon dioxide, CO₂.

This reaction rate is made faster by an increase in temperature and by a decrease in pressure of the soda.

[tex]M_{acid}=0.563M[/tex]

Explanation:

Hello there!

In this case, given the neutralization of the acetic acid as a weak one with sodium hydroxide as a strong base, we can see how the moles of the both of them are the same at the equivalence point; thus, it is possible to write:

[tex]M_{acid}V_{acid}=M_{base}V_{base}[/tex]

Thus, we solve for the molarity of the acid to obtain:

[tex]M_{acid}=\frac{M_{base}V_{base}}{V_{acid}} \\\\ M_{acid}=\frac{33.98mL*0.1656M}{10.0mL}\\\\ M_{acid}=0.563M[/tex]

Answer:

change in energy of the system = - 21 J

Explanation:

Δu = q + w

q = 364 J

w = - 385

Temperature of system drops from 25°c to 20°c

hence

Δu ( change in energy ) = q - w

                                       = 364 - 385

                                       = -21  J

Answer:

the volume occupied by 3.0 g of the gas is 16.8 L.

Explanation:

Given;

initial reacting mass of the helium gas, m₁ = 4.0 g

volume occupied by the helium gas, V = 22.4 L

pressure of the gas, P = 1 .0 atm

temperature of the gas, T = 0⁰C = 273 K

atomic mass of helium gas, M = 4.0 g/mol

initial number of moles of the gas is calculated as follows;

[tex]n_1 = \frac{m_1}{M} \\\\n_1 = \frac{4}{4} = 1[/tex]

The number of moles of the gas when the reacting mass is 3.0 g;

m₂ = 3.0 g

[tex]n_2 = \frac{m_2}{M} \\\\n_2 = \frac{3}{4} \\\\n_2 = 0.75 \ mol[/tex]

The volume of the gas at 0.75 mol is determined using ideal gas law;

PV = nRT

[tex]PV = nRT\\\\\frac{V}{n} = \frac{RT}{P} \\\\since, \ \frac{RT}{P} \ is \ constant,\ then;\\\frac{V_1}{n_1} = \frac{V_2}{n_2} \\\\V_2 = \frac{V_1n_2}{n_1} \\\\V_2 = \frac{22.4 \times 0.75}{1} \\\\V_2 = 16.8 \ L[/tex]

Therefore, the volume occupied by 3.0 g of the gas is 16.8 L.

The volume occupied by 3.0 g of He is mathematically given as

V2=16.8L

Question Parameters:

If 4.0 g of helium gas occupies a volume of 22.4 L at 0 o C and a pressure of 1.0 atm, what volume does 3.0 g of H

Generally, the equation for the gas equation  is mathematically given as

PV=nRT

When the reacting mass is 3g

n2=3/4

n2=0.75

Therefore

V1/n1=V2/n2

Where

n1=1

[tex]V2=\frac{22.4*0.75}{1}[/tex]

V2=16.8L

Explanation:

If you follow traditional rounding, Na atomic mass is 23 and Cl atomic mass 35, 23 +35 = 58.

Answer:

The correct answer is - directly; Avogadro’s.

Explanation:

At the same temperature and pressure, gases of the same or equal volume have the same number of molecules. The relation between the moles of the gases and the volume of the gases are indirectly proportional to one another at the same temperature and pressure. This law is called Avogadro's law. In the case of an ideal gas of a particular mass has the volume and moles are directly proportional.

Thus, the correct answer is - directly; Avogadro’s.

Answer:

Explanation:

Let's do an equilibrium chart for the reaction of combustion of ammonia:

2NH₃(g) + (3/2)O₂(g) ⇄ N₂(g) + 3H₂O(g)

4.8atm 1.9atm 0 0 Initial

-2x -(3/2)x +x +3x Reacts (stoichiometry is 2:3/2:1:3)

4.8-2x 1.9-(3/2)x x 3x Equilibrium

At equilibrium the velocity of formation of the products is equal to the velocity of the formation of the reactants, thus the partial pressures remain constant.

If pN₂ = 0.63 atm, x = 0.63 atm, thus, at equilibrium

pNH₃ = 4.8 - 2*0.63 = 3.54 atm

pO₂ = 1.9 -(3/2)*0.63 = 0.955 atm

pH₂O = 3*0.63 = 1.89 atm

The pressure equilibrium constant (Kp) is calculated with the partial pressure of the gases substances:

Kp = [(pN₂)*(pH₂O)³]/[(pNH₃)²*]

Kp = [0.63*(1.89)³]/[(3.54)²*]

Kp = 4.2533/11.6953

Kp = 0.364

Answer:

Exactly the same approach can be used for determination of bromides. Other halides and pseudo halides, like I- and SCN-, behave very similarly in the solution, but their precipitate tends to adsorb chromate anions making end point detection difficult.

Mohr method is the titration method, used for the determination of the chloride ion concentration in solution. It can not be used for iodine ions, as the alkaline titration is not suitable for iodine.

Titration is the analytical process used for the determination of the concentration of a compound, by reacting it with titrant.

The mohr method is the titration method, that determines the concentration of the cations in the solution by titrating them with the salt. The salt formed precipitate in the reaction and the end point is determined.

The limitation to the use of mohr method, is its inability for the analysis of the chlorides of cations, as the reaction is carried out at high pH in alkaline conditions.

The iodide slats are suitably precipitated in the alkaline solution, and thus limits the use of the mohr method.
