When fossil fuels are burnt, what 2 gases are given off?
When fossil fuels are burnt, the following are one of the two gases when they are given off:
→ Carbon dioxide: Carbon dioxide is a green house gas, and plays a major role in the global warming.
→ Carbon Monoxide: Carbon monoxide is a gas that is dangerous to human beings when released.
Hope I helped (:
Have a great day!
