Introduction:
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.
