Relating ΔH to Quantities of Reactants and Products
How much heat is released when 4.50 g of methane gas is burned in a constant-pressure system? (Use the information given in Equation)
CH4(g) + 2O2(g)→CO2(g) + 2H2O(l) ΔH = –890 kJ
Hydrogen peroxide can decompose to water and oxygen by the reaction
2 H2O2(l) →2 H2O(l) + O2(g) ΔH = –196 kJ
Calculate the quantity of heat released when 5.00 g of H2O2(l) decomposes at constant pressure.
