When hydrogen peroxide (H2O2) is used in rocket fuels, it produces water, oxygen, and heat.
2H2O2(l)⟶2H2O(l)+O2(g)ΔH=−196kJ
How many kilojoules are released when 2.65 moles of H2O2 reacts?
How many kilojoules are released when 234 g of O2 is produced?

a.
196 kJ x 2.65/2.00 = ? kJ produced.
b.
2 mols H2O2 = 2*34 = 68 g.
196 x (234/68) = ? kJ produced.
196 kJ x 2.65/2.00 = ? kJ produced.
