Answer:

D - sulfuric acid

Explanation:

Sulfuric acid is the chief offender in the acid precipitation formation. Sulfur dioxide is delivered from nitrogen oxides and power plants which come from car exhaust. When this pollution enters the atmosphere, they can explore hundreds of miles until they combine with the moisture in the environment which further forms the acids that ultimately reach the surface of the earth and cause damage.

No unpaired electrons → diamagnetic

O→ Group 6A → 6 valence electrons

12 valence electrons TOTAL.

2 unpaired electrons → paramagnetic

N→ Group 5A → 5 valence electrons

O→ Group 6A → 6 valence electrons

11 valence electrons TOTAL.

1 unpaired electron → paramagnetic

500 because of the 10% rule when moving up in food chains, for example; patch of grass-200J rabbit eats some of it but doesn’t eat all - 150J the rabbit runs around for a bit and loses energy, the fox doesn’t eat all of the rabbit - 50J ( just a rough example may not be completely right but the concept of the rule is there and the energy).
