Question

______ gas is released by the burning of fuels in vehicles and factories​

Answer 1

Carbondioxide (CO2) is released by the burning of fuels in vehicles and factories.

Answer 2

Explanation:

Gases released into the atmosphere by fuel combustion process are: CO2, SO2, H2O, N2, O2, CO, NOx, PAHs (polycyclic aromatic hydrocarbons), VOCs (volatile organic compounds), dioxins, furans.

The vapors given off when gasoline evaporates and the substances produced when gasoline is burned (carbon monoxide, nitrogen oxides, particulate matter, and unburned hydrocarbons) contribute to air pollution. Burning gasoline also produces carbon dioxide, a greenhouse gas.
