Chapter 4, Problem 4.65QP

(a)

Interpretation Introduction

Interpretation:

A balanced equation for the given reaction has to be written.

“Ammonia is formed by the reaction of nitrogen and hydrogen”

Concept Introduction:

Balancing the equation:

• There is a Law for conversion of mass in a chemical reaction i.e., the mass of total amount of the product should be equal to the total mass of the reactants.
• First write the skeletal reaction from the given information.
• Then count the number of atoms of each element in reactants as well as products.
• Place suitable coefficients in front of reactants as well as products until the number of atoms on each side (reactants and products) becomes equal.
