Nitrogen reacts with hydrogen to produce ammonia. The chemical equation for this reaction, located below, indicates all of the following information except... N2(g) + 3 H2(g) ---> 2 NH3(g)

Select one:
a. All substances are in the same physical state.
b. One molecule of ammonia is composed of two atoms of nitrogen and three atoms of hydrogen.
c. Two molecules of ammonia are produced.
d. Three molecules of hydrogen react with one molecule of nitrogen.

I think the answer is:

C. two molecules of ammonia are produced.

b. One molecule of ammonia is composed of two atoms of nitrogen and three atoms of hydrogen.

Explanation:

N2(g) + 3 H2(g) ---> 2 NH3(g)

reason its b.
1 molecule of ammonia would be NH3 , there is 1 atom of nitrogen and 3 atoms of hydrogen. There is not 2 atoms of nitrogen in one molecule of ammonia therefore the reaction does not indicate B.

Reasons its not a, c or d

A. The g means "gas". Each compound and element in this reaction has a g therefore they are all gases. Because all substances in the reaction are gases (or in the same physical state) the reaction indicates answer choice A.

C. That two molecules of ammonia are produced, the product of the reaction is 2NH3. NH3 is ammonia and there is a coefficient of 2 before the NH3 so 2 molecules of ammonia is produced during the reaction.

D. 1 molecule of nitrogen ( N2 ) reacts with 3 molecules of hydrogen ( 3H2 ). This is true looking at the reaction. N2(g) + 3 H2(g)
