1) If 50 kJ of heat are given off by a chemical reaction in aqueous solution and all the heat is absorbed by the surrounding water, what are the numerical values of:
a) q system b) q surroundings
2) If 100 g of water undergo a temperature increase of 5.5°C, what is the heat change (q) of the water?
3) If a calorimeter has a mass of 6.0g, a specific heat of 10. J/(g •°C), and it and its contents undergo a temperature increase of 5.5°C, how much heat is gained by the calorimeter?
