Heat of Combustion is the energy released as heat when a compound undergoes complete combustion with Oxygen.
The first part of your question doesn't have enough information for me to answer, but I can answer the last part:
The specific heat of water is 4184 J/(kg·C).
So, if you have 20 grams of water, heated 9 degrees, the heat absorbed is:
specific heat * mass * change in temperature =
4184 J/(kg·C) * .02 kg * 9 degrees C = 753.12.
