Balancing Chemical Equations

Balance the following chemical equation:

HCl + O 2     H 2 O + Cl 2

Interpretation Introduction

Interpretation:

The given chemical equation is to be balanced.

Concept Introduction:

Chemical reactions are represented by chemical equations, where the starting material acting as the reactants are written on the left side, whereas the products are written on the right side of the equation.

For any chemical equation to be balanced, the number of atoms of each element on both sides of the arrow should be equal.

Addition of coefficients to both reactants and products makes the number of atoms of each type of element on both sides equal, thereby making the equation balanced.

Explanation of Solution

For the given chemical equation, hydrogen atoms are balanced first as follows:

HCl+ O2 H2O+ Cl22HCl+ O2 H2O+ Cl2

Now balance the oxygen atom as follows:

2HCl+ 12O2 H2O+
