A 275-g. sample of nickel at 100 degrees C is placed in 100 g. of water at 22 degrees C. What is the final temperature of water? Assume that no energy is gained or lost to the calorimeter or the surroundings. Specific heat capacity of nickel = .444 J/ (g*k).

• chemistry -

Heat lost by nickel + heat gained by water = 0

[mass Ni x specific heat Ni x (Tfinal-Tinitial)] + [mass H2O x specific heat H2O x (Tfinal-Tinitial)] = 0
