Chapter 3, Problem 66QRT

(a)

Interpretation Introduction

Interpretation:

The reaction of ammonium nitrate gives laughing gas (dinitrogen monoxide) and water has to be written and balanced.

Concept introduction:

Balancing reaction:

Balanced reaction is a chemical reaction in which number of atoms for each element in the reaction and the total charge are same on both reactant side and the product side.

Steps in balancing the information

• Step 1: Write the unbalanced equation
• Step 2: Find the coefficient to balance the equation.
• The coefficient should be reduced to the smallest whole number.

(b)

Interpretation Introduction

Interpretation:

The masses of ${\text{N}}_{\text{2}}\text{O}$ and water that are produced from $\text{10}\text{.0 g}$ ammonium nitrate has to be calculated.

Concept introduction:

The number of moles is calculating by using following formula,

    $No.ofmoles=\frac{Mass\times 1mol}{Molarmass}$

The mass is calculating by using following formula,

  $Mass=No.ofmoles\times Molarmass$
