12) Most nitrogen exists in a gaseous state. Plants require a soluble form of nitrogen so they can absorb it from the ground. Ammonia is a good fertilizer, as the mass
percent of nitrogen in ammonia is very high. The following reaction is used to
convert gaseous nitrogen into ammonia, which can be used as fertilizer.
N2(g) + 3 H2(g) → 2 NH;
Suppose 186.3 g of N2(g) react with 289.8 g of H2(g).
a. Which reactant is limiting? Justify your answer.
b. What mass of ammonia can be produced in theory?
c. If this reaction is know to have a 73.8% yield, what mass of ammonia
could you expect to produce?

What is the mass of each element in a 324.8 sample of co2

What term is applied to a scientist who studies ancient life, including animal and plant fossils a. anthropologist b. dendroclimatologist c. geophysicist d. paleontologist

Answer the questions about this reaction: nai(aq) + cl2(g) → nacl(aq) + i2(g) write the oxidation and reduction half-reactions: oxidation half-reaction: reduction half-reaction: based on the table of relative strengths of oxidizing and reducing agents (b-18), would these reactants form these products? write the balanced equation: answer options: a. 0/na -> +1/na+1e- b. nai(aq) + cl2(g) → nacl(aq) + i2(g) c. +1/na+1e- -> 0 /na d. -1/2i -> 0/i2+2e- e. no f. 4nai(aq) + cl2(g) → 4nacl(aq) + i2(g) g. 2nai(aq) + cl2(g) → 2nacl(aq) + i2(g) h. 4nai(aq) + 2cl2(g) → 4nacl(aq) + 2i2(g) i. nai(aq) + cl2(g) → nacl(aq) + i2(g) j. 0/cl2+2e -> -1/2cl- k. yes
