Answer:

6.8 mole of O₂

Explanation:

Given expression:

2H₂ + O₂ → 2H₂O

Number of moles of H₂ = 13.6moles

Unknown:

Number of moles of O₂ = ?

Solution:

In the given problem, we are to find the number of moles of oxygen gas that will use up 13.6mole of hydrogen gas;

From the reaction equation;

2 mole of H₂ will completely react with 1 mole of O₂

13.6 moles of H₂ will completely be used up by $\frac{13.6}{2}$ mole of O₂

= 6.8 mole of O₂

In the reaction 2H2O (1)+ 2Cl^- (aq)= H2(g)+Cl2 (g)+ 2OH^-(aq), which substance is reduced?

Oksanka [162]

Answer:- C. H

Explanations:- Reduction is gain of electron. In other words we could say that decrease in oxidation number is reduction.

As per the rules, oxidation number of hydrogen in its compounds is +1(except metal hydrides) and the oxidation number of oxygen in its compounds is -2.

The oxidation number in elemental form is zero.

In $H_2O$ , the oxidation number of H is +1 and oxidation number of O is -2. Oxidation number of Cl in $Cl^-$ is -1. On product side, the oxidation number of hydrogen in $H_2$ is zero and in $OH^-$ the oxidation number of H is +1 and that of O is -2. Oxidation number of Cl in $Cl_2$ is 0.
