Chapter 6, Problem 20A

Summary Introduction

Introduction:

Chemical reaction is a process in which one or more reactants are changed to one or more different substances, that is called products. In a chemical reaction where reactants react with each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

Answer to Problem 20A

Correct answer :

The correct answer is option B. Products are on the right.

Explanation of Solution

Explanation/justification for the correct answer :

Option B. Products are on the right. A chemical equation is the depiction of a chemical reaction in the form of symbols and formulae, where the reactants are given on the left side and the products on the right side. So, the correct answer is option B.

Explanation for incorrect answer :

Option A. Reactants are on the right. In a chemical reaction, reactants are starting materials which are written on the left-hand side of the equation. So, this is an incorrect answer.

Option C. Products have fewer atoms than reactants. A balanced chemical equation happens when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side. So, this is an incorrect answer.

Option D. Reactants have fewer atoms than products. Balanced chemical equations have the same number and type of each atom on both sides (reactant and product side) of the equation. So, this is an incorrect answer.
