Yes, that is true
carbon dioxide
Carbon monoxide and methane
Carbon monoxide (CO) is a substance that is uniquely a product of incomplete combustion of a fossil fuel. It is a colorless, odorless gas that can be harmful when inhaled in high concentrations.
No, carbon is in fossil fuels.
The main product is carbon dioxide. Aproximatlely 3 kg of carbon dioxide is produced by burning 1 kg of fossil fuel. The extra mass is from the oxygen taken from the atmosphere during burning.
The internal combustion engine ignites the fuel. That fuel then expands as it burns into carbon dioxide. Carbo ndioxide is what is left from the burning of fossil fuels.
Carbon dioxide
Yes, coal is a carbon based fossil fuel.
Fossil fuel
As fossil fuels are made up of Carbon and Hydrogen. This burns in oxygen (in air) to form Carbon dioxide and Water, so the carbon dioxide is released into the air
Fossil fuel and it burns
Fossil fuel (hydrocarbon) + oxygen -> carbon dioxide + water + energy
