Which of the following happens when fossil fuels are burned? carbon dioxide and other pollutants are released into the air. carbon dioxide and other pollutants are removed from the air. radioactive waste is produced. iron, lead, and zinc are produced

A

Consider the burning of Methane which is one of the cleanest burning fuels that we use.

CH4 + 2O2 > CO2 + 2H2O

What is released is CO2 and water. Mind you, this is among the cleanest of the fossil fuels.

So both C and D are wrong. There are no radioactive substances released and nothing even remotely resembling iron, lead and zinc are released. Five decades or so ago, unleaded gasoline was introduced. Up until that time, lead was released into the atmosphere. No longer.

Methane does not act like a tree and our vehicles don't either. Our cars release CO2. They don't breathe it in.

The best answer is A

Carbon dioxide and other pollutants are released into the air.
