1) A 17.27 gram sample of aluminum initially at 92 degrees Celsius is added to a container containing water. The final temperature of the metal is 25.1 degrees Celsius. What is the total amount of energy in Joules added to the water? What was the energy lost by the metal?

2) Mixing 25.0 mL of 1.2 M HCl and 25.0 mL of 1.1 M NaOH were mixed. The temperature of the initial solution was 22.4 degrees Celsius. Assuming a Heat of Neutralization of -55.8 KJ/mol, what would the final temperature be if the specific heat for this solution is 4.03 J/g degrees Celsius?
