Chapter 6, Problem 6.69CP

a)

Interpretation Introduction

Interpretation:

The balanced chemical equation for the given reaction has to be written.

Concept Introduction:

Balanced chemical equation: In a chemical reaction the number of atoms for each element in the reaction and the total charge are the same for both the reactants and the products.

b)

Interpretation Introduction

Interpretation:

The no.of mole of gas produced by the reaction has to be calculated.

Concept Introduction:

Mole: The amount of substance containing as many elementary entities (atoms, molecules, ions, etc.) as there are atoms in 12 grams of carbon-12.

Mole calculation:

$\text{No}\text{.of moles =}\frac{\text{Mass }}{\text{molar mass}}$ Number of mole is obtained dividing Mass by molar mass.

Mass Calculation:$\text{No}\text{.of moles }\times \text{ molar mass = Mass }$ Multiplying no.of mole and molar mass gives mass of the substance.
