Calculate the resulting ph if 365 ml of 2.88 m hno3 is mixed with 335 ml of 1.10 m ca(oh)2 solution.

How many grams of aluminum will there be in 98g of al2o3?

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)
