Find q of a reaction. A cup calorimeter contains 50.0 mL of 0.500 M NaOH at 25C. Then 25.0 mL of .500 M HCl at 25 C is added. After reaction, the final temperature = 27.21 C. What is q in KJ? Given C=4.184 J/gK
Assume that a particular reaction evolves 231 of heat and that 20 of work is gained by the system. What are the values of delta E and delta H for both the system and the surroundings?
