2 NH3(g) - N2(g) + 3 Hz(8) The reaction for the decomposition of ammonia (NH3) can be written as shown. If a student starts with
95.7 g of NH3, how many grams of
hydrogen (H2) gas will be produced by the reaction

Describe the difference between a. a hypothesis and a theory and b. an observation and an experiment.

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)
