Problem: Balance each of the following chemical equations. Give your answer as coefficients separated by commas.HCl(aq) + O2(g) → H2O(l) + Cl2(g)

FREE Expert Solution

Unbalanced Reaction: HCl(aq) + O2(g) → H2O(l) + Cl2(g)

We have 1 Cl on the reactant side and 2 Cl on the product side → add a coefficient of 2 to HCl to balance Cl:

2 HCl(aq) + O2(g) → H2O(l) + Cl2(g)

We have 2 O on the reactant side and 1 O on the product side → add a coefficient of 2 to H2O to balance O:

2 HCl(aq) + O2(g) → 2 H2O(l) + Cl2(g)
