Chapter 9.3, Problem 15PP

(a)

Interpretation Introduction

Interpretation: To determine the mass of H₂O required to react with 28.0 g of NO₂.

  ${\text{3NO}}_{\text{2}}\text{(g)}\text{+}{\text{H}}_{\text{2}}\text{O}\text{(l)}\to {\text{2HNO}}_{\text{3}}\text{(aq)}\text{+}\text{NO}\text{(g)}$

Concept Introduction:

A stoichiometric coefficient of a well-balanced chemical equation tells about the relative relation between moles of reactants used and moles of products formed.

Let’s say we have a chemical reaction as:

  $\text{aA}\text{+bB}\to \text{cC}\text{+}\text{dD}$

If above reaction is well-balanced then,

‘a’ moles of A reacts with ‘b’ moles of B to produce ‘c’ moles of C and ‘d’ moles of D.

(b)

Interpretation Introduction

Interpretation: To determine the mass of NO produced from 15.8 g of H₂O.

  ${\text{3NO}}_{\text{2}}\text{(g)}\text{+}{\text{H}}_{\text{2}}\text{O}\text{(l)}\to {\text{2HNO}}_{\text{3}}\text{(aq)}\text{+}\text{NO}\text{(g)}$

(c)

Interpretation Introduction

Interpretation: To determine the mass of HNO₃ produced from 8.25 g of NO₂.

  ${\text{3NO}}_{\text{2}}\text{(g)}\text{+}{\text{H}}_{\text{2}}\text{O}\text{(l)}\to {\text{2HNO}}_{\text{3}}\text{(aq)}\text{+}\text{NO}\text{(g)}$
