What chemical reaction is 2H2o2

Decomposition of hydrogen peroxide: 2H2O2 - -> O2 (g) + 2H2O (l) How many molecules of water are produced from the decomposition of 3.4g of hydrogen peroxide, H2O2

Explanation:

We are looking at the decomposition of hydrogen peroxide into water and oxygen gas:

2H2O2 - -> 2H2O + O2

We are starting with 3.4 g of H2O2. First we need to convert this to moles. The molecular weight of H2O2 is 34 g/mol

3.4 g * ...
