This chemical equation represents one of the reactions that form acid rain. Which two options list the bonds that break in the reaction?,

A. The bonds between H and O in H20

B. The bonds between N and O in NO2

C. The bonds between N and O and between Hand O in HNO2

D. The bonds between N and O and between Hand O in HNO3

A and B

Explanation:

Acid rain is formed when rain water has a pH of about 5.2 or below. It is caused by the presence of the oxides of nitrogen or sulphur in air. These oxides dissolve in rain water to form the corresponding mineral acids thereby decreasing the pH of rainwater.

If we look at the reaction;

2NO2 + H2O ---> HNO2 + HNO3

We will discover that the bonds broken are the bonds between;

I) H and O in H20

ii) N and O in NO2
