Hydrogen gives off 120. J/g of energy when burned in oxgyen, and methane gives off 50. J/g under the same circumstances. If the mixture of 5.0 g of hydrogen and 10. g of methane is burned, and the heat released is transferred to 50.0 g of water at 25.0 degress Celsius, what final temperature will be reached by the water?

1. 120 J/g x 5.0 g hydrogen = ?? J.
50 J/g x 10.0 g methane = ?? J.
total = ?? J = q
mass water x specific heat water x (Tfinal-Tinitial) = q
Solve for Tfinal.
