Which of the following numbers represent a subscript in this equation? 4NH3 + 5O2?4NO + 6H2O Check all that apply. A. 2 B. 3 C. 4 D. 6

Ok, first of all, this is in the wrong subject, but I'll answer it anyways.

4NH3 is 4 molecules of NH3, which is ammonia.

So the 3 in NH3 would be the subscript since there are three hydrogen molecules in one ammonia molecule.

5O2 is 5 molecules of O2, which is oxygen.

The subscript would be 2 since there are 2 oxygen molecules in oxygen.

6H2O is 6 molecules of H2O, which is water.

The subscript would be 2 since there are 2 hydrogen molecules in water.

So the subscripts are 3, 2, 2 or answer choices A and B.
