The temperature of a calorimeter has been increased by 12.3 K as a result of a certain chemical reaction. An electrical heater operating for 320 s at a voltage of 12 V and a current of 4.3 A in the same calorimeter elevated the temperature by 22.4 K. Calculate the heat capacity of the calorimeter and amount of heat released by the chemical reaction.
