If 50.0 g h2o at 13.6 c is combined with 85.0 g h2o at 93.7 c, what is the final temperature of the mixture? the specific heat capacity of water is 4.184 j/g·k.

Given the following at 25c calculate delta hf for hcn (g) at 25c. 2nh3 (g) +3o2 (g) + 2ch4 (g) > 2hcn (g) + 6h2o (g) delta h rxn= -870.8 kj. delta hf=-80.3 kj/mol for nh3 (g), -74.6 kj/mol for ch4, and -241.8 kj/mol for h2o (g)
