determine the final temperature of a system after 100.0g of zinc ( specific heat .3876 J/g c) at 95.0 C is immersed into 50.0 g of water at 15.C
heat lost by Zn + heat gained by H2O = 0
[mass Zn x specific heat Zn x (Tfinal-Tinitial)] + [mass H2O x specific heat H2O x (Tfinal-Tinitial)] = 0
Solve for Tf, the only unknown.
