Fossil fuel combustion increases the acidity of rain because
a. sulfuric acid and nitric acid dissolve in rainwater
b. tiny particles of carbon dissolve in rainwater
c. carbon dioxide dissolves in rainwater
d. sulfur dioxide and nitrogen oxides dissolve in rainwater

D. sulfur dioxide and nitrogen oxides dissolve in rainwater

Explanation:

Sulfur dioxide and nitrogen oxides are by products of fossil fuel combustion. The bulk of these gases are released into the atmosphere. When these gases gets to the atmosphere, they combine with rain water to form acid rain.

The oxides, sulfur dioxde and nitrogen oxides are non-metallic oxides. They are acid oxides that combines with water to produce an acid.

Burning of fossil fuels release these gases and they combine with rain water to form acid rain.

Acid rain is very corrosive and greatly affects the ecosystem.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
