Your friend offers to show you an intrusive igneous rock. which of the following would you expect to see?

How many moles of oxygen gas are produced from the decomposition of six moles of potassium chlorate

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)
