The name of the positively charged nonmetal ion is changed to end in –ide, is not true of binary compounds.

Hope this help!

The answer is: The name of the positively charged nonmetal ion is changed to end in –ide.

For example, a chemical compound containing sodium and chlorine is binary ionic compound sodium chloride (NaCl).

In this compound, sodium (Na) has positive charge and chlorine (Cl) has negative charge.

Chlorine is nonmetal and sodium is metal.

Metals have positive charge and nonmetals negative.

Coal, which is primarily carbon, can be converted to natural gas, primarily CH4, by the following exothermic reaction: C(s)+2H2(
LuckyWell [14K]

Answer:

A. The reaction will proceed forward forming more CH4

B. The reaction will proceed forward forming more CH4

C. Since the reaction is exothermic, raising the temperature will cause the reaction to proceed backward, thus forming C and H2.

D. Lowering the volume makes the gas particles to be more close together thereby enhancing their collisions leading to reaction. Therefore the reaction will proceed forward forming more CH4

E. Catalyst only reduce the activation energy so the reaction can proceed faster. The reaction will proceed forward forming.

F. The following will favour CH4 at equilibrium

i. Catalyst to the reaction mixture,

ii. Both adding more H2 to the reaction mixture and lowering the volume of the reaction mixture

iii. Adding more C to the reaction mixture.

Show the calculation of the mole fraction of each gas in a 1.00 liter container holding a mixture of 8.65 g of CO2 and 4.32 g of
Vlad1618 [11]

Answer:

0.745 and 0.245

Explanation:

Mole fraction (χ) is  the number of moles of a component divided by the total number of moles in a mixture.  

We must calculate the moles of each component.  

Let CO₂ be Gas 1 and SO₂ be Gas 2.

1. Calculate the moles of each gas.

\text{n} _{1} = \text{8.65 g} \times \dfrac{\text{1 mol}}{\text{44.01 g}} = \text{0.1965 mol}\\\\\text{n} _{2} = \text{4.32 g} \times \dfrac{\text{1 mol}}{\text{64.06 g}} = \text{0.067 44 mol}

2. Calculate the total moles.

n_{\text{tot}} = \text{n}_{1} + \text{n}_{2} = \text{0.1965 mol} +\text{0.067 44 mol} = \text{0.2640 mol}

3. Calculate the mole fraction of each component

\chi_{1} =\dfrac{0.1965}{0.2640} = \mathbf{0.745}\\\\\chi_{2} =\dfrac{0.06744}{0.2640} = \mathbf{0.255}
