NH3 (g) + O2 (g) ---> NO2 (g) + H2O (g)

a. 1,1,1,1
b. 4,7,4,6
c. 2,3,2,3
d. 1,3,1,2
e. 4,3,4,3

Answer 1

B

Step-by-step explanation:

Option B is the correct answer. When you add 7 in front of the O2 in the left side, and then you add 4 and 6 in front of NO2 and H2O respectively, the number of oxygen atoms is the same in both sides.
