Chapter 5, Problem 5.18UKC

Interpretation Introduction

Interpretation:

For the given reaction the correct representation of reactant and product should be determined from the given options.

Concept introduction:

In a balanced equation the number of atoms of each element as a reactant is equal to the number of atoms of that element as a product.

Coefficient is a number placed before a formula in a chemical equation.

A balanced equation should be obeying the law of conservation of mass. Law of conservation of mass states that, the number of atoms remains constant throughout the reaction, simply it can be stated as follows, “during a chemical reaction atoms are neither be created nor be destroyed”.

In a chemical reaction, one or more new substances are formed.

The starting materials used in a reaction are reactants and the new substances formed in a reaction are products.
