Chapter 2, Problem 22P

(a)

Interpretation Introduction

Interpretation: The mass of ${\text{CaCO}}_{\text{3}}$ that is required to produce 1.000 g of ${\text{Ca(OH)}}_{\text{2}}$ in the given chemical reaction needs to be determined.

  ${\text{CaCO}}_{\text{3 }}{\text{ + H}}_{\text{2}}\text{O}\stackrel{}{\to }{\text{Ca(OH)}}_{\text{2}}{\text{ + CO}}_{\text{2}}$

Concept Introduction: A chemical reaction is symbolic representation of the conversion of substances to new substances. In a chemical reaction; the substance which involves in conversion is said to be reactant whereas the newly formed substance is called as product. Both reactant and products must be separated by arrow.

To determine the amount of product formed or amount of reactant used, mole concept can be used to do that. The relation between moles, mass and molar mass can be calculate with the help of given formula:

  $\text{Moles = }\frac{\text{Mass (g)}}{\text{Molar mass (g/mol)}}$

(b)

Interpretation Introduction

Interpretation: The mass of ${\text{C}}_{\text{3 }}{\text{H}}_{\text{8}}$ that is required to produce 1.000 g of ${\text{CO}}_{\text{2}}$ in the given chemical reaction needs to be determined.

  ${\text{C}}_{\text{3 }}{\text{H}}_{\text{8}}{\text{ + 5 O}}_{\text{2}}\stackrel{}{\to }{\text{3 CO}}_{\text{2}}{\text{+ 4 H}}_{\text{2}}\text{O}$

Interpretation Introduction

Interpretation: The mass of ${\text{MgNH}}_{\text{4}}{\text{PO}}_{\text{4}}$ that is required to produce 1.000 g of ${\text{Mg}}_{\text{2}}{\text{P}}_{\text{2}}{\text{O}}_{\text{7}}$ in the given chemical reaction needs to be determined.

  ${\text{2 MgNH}}_{\text{4}}{\text{PO}}_{\text{4}}\stackrel{}{\to }{\text{Mg}}_{\text{2}}{\text{P}}_{\text{2}}{\text{O}}_{\text{7}}{\text{+ 2 NH}}_{\text{3}}{\text{+ H}}_{\text{2}}\text{O}$
