Hydrogen peroxide = H2O2 (aq)
Complete reaction: H2O2 (aq) → H2O (l) + O2 (g)
When balancing chemical equations, the number of each atom must be the same on both sides of the equation.
Hydrogen peroxide (H2O2) decomposes in the presence of a catalyst to form water and oxygen. The catalyst is added to 5.00 mL of a hydrogen peroxide solution at 25.0 C, and 49.5 mL of gas is collected over water at a total pressure of 763.6 mmHg.
Write and balance the chemical reaction (note: catalysts do not appear in balanced chemical equations). Express your answer as a chemical equation including phases.
