Answers

Answer 1

Answer: The equilibrium concentration of [tex]CH_4[/tex] , expressed in scientific notation is [tex]5.9\times 10^{-2}M[/tex]

Explanation:

Equilibrium constant is the ratio of the concentration of products to the concentration of reactants each term raised to its stochiometric coefficients.

The given balanced equilibrium reaction is,

                          [tex]CO(g)+3H_2(g)\rightleftharpoons CH_4(g)+H_2O(g)[/tex]

At eqm. conc.     (0.30) M     (0.10) M      (x) M   (0.020) M

The expression for equilibrium constant for this reaction will be,

[tex]K_c=\frac{[CH_4]\times [H_2O]}{[CO]\times [H_2]^3}[/tex]

Now put all the given values in this expression, we get :

[tex]3.90=\frac{x\times (0.020)}{(0.30)\times (0.10)^3}[/tex]

By solving the term 'x', we get :

x = 0.059 M=  [tex]5.9\times 10^{-2}M[/tex]

Thus, the concentrations of [tex]CH_4[/tex] at equilibrium is :

Concentration of [tex]CH_4[/tex] = (x) M  = [tex]5.9\times 10^{-2}M[/tex]

The equilibrium concentration of [tex]CH_4[/tex] , expressed in scientific notation is [tex]5.9\times 10^{-2}M[/tex]

An aqueous solution of glucose (MM = 180.2 g/mol) has a molality of 2.27 m and a density of 1.20 g/mL. What is the molarity of glucose in the solution?

**Any help would be greatly appreciated!**

Answers

Answer:

Molarity of the glucose solution = 2.72 mol/L

Explanation:

Molality of a solution is defined as the number of moles of solute per kilogram of solvent.

Therefore , a 2.27 molal solution of glucose contains 2.27 moles of glucose in 1 Kg of solvent

Density of solution = 1.20 g/mL

The volume occupied by 1 Kg or 1000 g solution = mass/density

Volume of 1000 g solution = 1000 g/1.20 g/ml = 833.3 mL

Number of moles of glucose present in the solution = 2.27 moles

Molarity = number of moles / volume(L)

volume of solution in litres = 883.3/1000 = 0.8333 L

Molarity = 2.27 moles /0.8333 l = 2.72 mol/L

Therefore, molarity of the glucose solution = 2.72 mol/L

The molarity of the glucose in the solution has been 2.72 mol/L.

Molality can be defined as the moles of the solute per kg of solvent.

The molality of glucose solution = 2.27 m

2.27 moles of glucose in 1000 grams of water.

Density has been the mass per unit volume. The density can be expressed as:

Density = [tex]\rm \dfrac{Mass}{Volume}[/tex]

The density of the given glucose solution = 1.20 g/ml

The volume of 1000 grams of water has been:

Volume = [tex]\rm \dfrac{Mass}{Density}[/tex]

Volume of 1000 grams water = [tex]\rm \dfrac{1000\;g}{1.20\;g/ml}[/tex]

Volume of 1000 g water = 833.3 ml

The molarity can be defined as the mass of solute per liter of the solution.

Molarity = [tex]\rm moles\;\times\;\dfrac{1000}{Volume\;(ml)}[/tex] ......(i)

The moles of glucose in the 833.3 ml solution have been 2.27 mol.

Substituting the values in equation (i):

Molarity = 2.27 mol [tex]\rm \times\;\dfrac{1000}{833.3\;ml}[/tex]

Molarity = 2.72 mol/L.

The molarity of the glucose in the solution has been 2.72 mol/L.

Using the balanced equation below, how many grams of iron(iii) oxide would be required to make 187g iron Fe2O3+3CO = 2Fe+3CO2

Answers

Answer:

267.14 iron oxide.

Explanation:

Given that

[tex]Fe_2O_3+3CO = 2Fe+3CO_2[/tex]

We know that molecular mass of iron-oxide = 160 g/mole.

We know that molecular mass of iron = 56 g/mole.

From the above reaction we can say that

1 mole of iron -oxide produce 2 mole of iron

160 gm of iron oxide produce 112 gm of iron

So

1 gm of iron required [tex]\dfrac{160}{112}=1.42 gm[/tex] of iron oxide

Therefore

187 gm of iron required [tex]1.42\times = 187 = 267.14\ gm[/tex] of iron oxide.

Therefore 187 gm of iron required 267.14 iron oxide.

5. How many atoms and molecules of sulphur are present in 64.0 g of sulphur (S 8 )?

Answers

Answer:

There are [tex]1.202\times 10^{24}[/tex] atoms and [tex]1.502\times 10^{23}[/tex] molecules in the compound.

Explanation:

The molar mass of the sulphur is [tex]32.065\,\frac{g}{mol}[/tex]. The Avogradro's Law states that exists [tex]6.022\times 10^{23}\,\frac{atom}{mol}[/tex]. The quantity of atoms in a quantity of mass is derived from dividing the mass by the molar mass and multiplying it by the Avogadro's Number. That is:

[tex]n_{atom} = m_{S}\cdot \frac{n_{A}}{M_{S}}[/tex]

Where:

[tex]m_{S}[/tex] - Mass of the sample, measured in grams.

[tex]n_{A}[/tex] - Avogadro's Number, measured in atoms per mole.

[tex]M_{S}[/tex] - Molar mass of the sulphur, measured in grams per mole.

If [tex]m_{S} = 64\,g[/tex], [tex]n_{A} = 6.022\times 10^{23}\,\frac{atoms}{mol}[/tex] and [tex]M_{S} = 32.065\,\frac{g}{mol}[/tex], then:

[tex]n_{atom} = (64\,g)\cdot \left(\frac{6.022\times 10^{23}\,\frac{atoms}{mol} }{32.065\,\frac{g}{mol} }\right)[/tex]

[tex]n_{atom} = 1.202\times 10^{24}\,atoms[/tex]

There are [tex]1.202\times 10^{24}[/tex] atoms in the compound.

Now, the molecular weight of the compound is:

[tex]M_{S_{8}} = 8\cdot \left(32.065\,\frac{g}{mol} \right)[/tex]

[tex]M_{S_{8}} = 256.52\,\frac{g}{mol}[/tex]

The quantity of molecules in a quantity of mass is derived from dividing the mass by the molecular weight and multiplying it by the Avogadro's Number. That is:

[tex]n_{molecule} = m_{S_{8}}\cdot \frac{n_{A}}{M_{S_{8}}}[/tex]

Where:

[tex]m_{S_{8}}[/tex] - Mass of the sample, measured in grams.

[tex]n_{A}[/tex] - Avogadro's Number, measured in atoms per mole.

[tex]M_{S_{8}}[/tex] - Molecular weight of the compound (octosulphur), measured in grams per mole.

If [tex]m_{S_{8}} = 64\,g[/tex], [tex]n_{A} = 6.022\times 10^{23}\,\frac{molecules}{mol}[/tex] and [tex]M_{S_{8}} = 256.52\,\frac{g}{mol}[/tex], then:

[tex]n_{molecule} = (64\,g)\cdot \left(\frac{6.022\times 10^{23}\,\frac{molecules}{mol} }{256.52\,\frac{g}{mol} }\right)[/tex]

[tex]n_{molecule} = 1.502\times 10^{23}\,molecules[/tex]

There are [tex]1.502\times 10^{23}[/tex] molecules in the compound.

The density of a gaseous chlorofluorocarbon (CFC) at 23.8 °C and 432 mmHg is 3.23 g/L. What is its molar mass?

Answers

Answer:

138.57 g/mol.

Explanation:

The following data were obtained from the question:

Temperature (T) = 23.8 °C

Pressure = 432 mmHg

Density (D) = 3.23 g/L

Next, we shall obtain an expression for the density in relation to molar mass, pressure and temperature.

This can be obtained by using the ideal gas equation as shown below:

PV = nRT.... (1)

Recall:

Mole (n) = maas(m) /Molar mass (M)

n = m/M

Substituting the value of n into equation 1

PV = nRT

PV = mRT/M

Divide both side by P

V = mRT/MP

Divide both side by m

V/m = RT/MP

Invert the above equation

m/V = MP /RT..... (2)

Recall:

Density (D) = mass(m) /volume (V)

D = m/V

Replace m/V with D in equation 2

m/V = MP /RT

D = MP /RT

Thus, with the above formula we can obtain the molar mass of chlorofluorocarbon (CFC) as shown below:

Temperature (T) = 23.8 °C = 23.8 °C + 273 = 296.8 K

Pressure = 432 mmHg = 432/760 = 0.568 atm

Density (D) = 3.23 g/L

Gas constant (R) = 0.0821 atm.L/Kmol

Molar mass (M) =..?

D = MP /RT

3.23 = M x 0.568 / 0.0821 x 296.8

Cross multiply

M x 0.568 = 3.23 x 0.0821 x 296.8

Divide both side by 0.568

M = (3.23 x 0.0821 x 296.8) / 0.568

M = 138.57 g/mol

Therefore the molar mass of CFC is 138.57 g/mol.

Explanation:

Quantum numbers refers to values that exactly describe the energy of electrons within an atom or a molecule. Electrons are known to possess a set of four quantum numbers used in describing the energy state of such electron. These quantum numbers are solutions to the Schrödinger wave equation for the hydrogen atom.

In describing any electron within the atom, the relevant set of four quantum numbers are: principal quantum number (n), orbital, azimuthal, subsidiary or angular momentum quantum number (l), magnetic quantum number (ml), and spin quantum number (ms).

In the arrangement above, the electrons are arranged in order of increasing energy. Each arrangement of quantum numbers corresponds to a particular energy state of the electron.

Which example is a long-term environmental change? La Niña El Niño climate change small asteroid impact

Answers

The correct answer is C. Climate change

Explanation:

Long-term environmental changes occur as major events affect the environment and ecosystems indefinitely. These events differ from short-term environmental changes because the effect of short-term environmental changes is mainly temporary. Also, long-term changes are usually gradual.

Climate change is an example of long-term environmental changes because this implies indefinite and major changes in weather patterns and ecosystems. For example, it is believed climate change will decrease the amount of ice in Earth, change sea level, and lead to the extinction of dozens of species. This does not occur with events such as el niño or a small asteroid impact that affect the environment for a short time and do not imply major changes.

Answers

Answer:

(iv) (A) is false, but (R) is true.

Explanation:

It is not true that carbon has a strong tendency to either lose or gain electrons to attain noble gas configuration. Carbon is a member of group 14, it is the first member of the group and carbon is purely a non metal. Only metals metals can loose electrons to attain the noble gas configuration. Moreover, carbon does not participate in ionic bonding so it does not gain electrons to attain the noble gas configuration.

However, carbon participates in covalent bonding where it is covalently bonded to four other chemical species using its four outermost electrons. Carbon forms covalent bonds in which four electrons are shared with other chemical species.

E ) The distribution coefficient , Ko ( Cether / C water ) , for an organic substance X at room temperature is 13. What relative volume of ether to water should be used for the extraction of 94 percent of X from a water solution in single extraction ?

Answers

Answer:

Relative volume of ether to water that should be used for the extraction = 1.205

Explanation:

The extraction/distribution coefficient of an arbitrary solvent to water for a given substance is expressed as the mass concentration of the substance in the arbitrary solvent (C₁) divided by the mass concentration of the substance in water (C₂).

K = (C₁/C₂)

Let the initial mass of the organic substance X in water be 1 g (it could be any mass basically, it is just to select a right basis, since we are basically working with percentages here).

If 94% of the organic substance X is extracted by ether in a single extraction, 0.94 g ends up in ether and 0.06 g of the organic substance X that remains in water.

Let the volume of ether required be x mL.

Let the volume of water required be y mL.

Relative volume of ether to water that should be used for the extraction = (x/y)

Mass concentration of the organic substance X in ether = (0.94/x)

Mass concentration of organic substance X in water = (0.06/y)

The distribution coefficient , Ko (Cether / C water), for an organic substance X at room temperature is 13.

13 = (0.94/x) ÷ (0.06/y)

13 = (0.94/x) × (y/0.06)

13 = (15.667y/x)

(x/y) = (15.667/13) = 1.205
