Chapter 3, Problem 3.40P

(a)

Interpretation Introduction

Interpretation: The balanced equation that corresponds to the statement when $\text{lead}\left(\text{II}\right)$ nitrate solution is added to potassium iodide solution and forms $\text{lead}\left(\text{II}\right)$ iodide and potassium nitrate solution should be written.

Concept introduction:In accordance with law of conservation of mass it is suggested total amount of reactants consumed is equal to the total amount of products formed in any balanced equation.

In order to balance an equation, one starts with the most complex chemical species and then place the appropriate coefficient so as to make the stoichiometric coefficient equal on each side.

After proper adjustment of coefficient, the atoms are checked for an equal number on each side and finally, the physical states of matter are written in parenthesis.

(b)

Interpretation Introduction

Interpretation: The balanced equation that corresponds to the statement when liquid disilicon hexachloride reacts with ${\text{H}}_{\text{2}}\text{O}$ to form solid ${\text{SiO}}_{\text{2}}$ , $\text{HCl}$ gas, and ${\text{H}}_2$ gas should be written.
