a)An 64.95 g sample of aluminum is placed on a 36.87 g sample of copper initially at 120.32oC. If the heat is only transferred between the metals (with no loss to the surroundings) and the final temperature of both metals is 37.68oC, what is the inital temperature (in oC) of aluminum?

b)How much heat (in kJ) is evolved (under standard conditions) when 209.14 g of copper reacts to form copper(II) oxide?

c)How much heat (in kJ) is needed when 61.38 g of water warms and boils from 40.01oC to 100oC?

d)What is recorded as the final temperature (in oC) on a constant pressure calorimeter if 12.403 g of potassium hydroxide is dissolved in 32.67 mL of water originally at 21.75oC?

There is no more data given in the problems that is whole question.
