Which description best matches complete combustion?

Carbon dioxide and water are produces and energy is given out
Carbon monoxide and carbon are produces as well as water and some energy is given out
Carbon dioxide only is given out
Water and carbon trioxide is given out and some energy

[question number = 05.2] Why is carbon monoxide produced during incomplete combustion?

Not enough oxygen is present to form carbon dioxide
Oxygen expands rapidly and escapes the reaction before forming carbon dioxide
Incomplete combustion involves burning sulfur and sulfur dioxide is made instead of carbon dioxide
Carbon monoxide is made in both complete and incomplete combustion

What toxic effects does carbon monoxide have on the body?

What is a common issue with soot (carbon) produced during combustion?

How do sulfur compounds get into hydrocarbon fuels like petrol and diesel?

Which gas that leads to acid rain is produced when hydrocarbons containing sulfur are burned?

[question number = 05.3] Which of the following are causes of acid rain?

Why does burning of fuel inside an internal combustion engine lead to the production of oxides of nitrogen?

Very high temperatures are required for oxygen to react with nitrogen
High pressures inside the engine causes the reaction
Nitrogen is present in the combustion chamber metal since it is an alloy
Nitrogen is injected by turbochargers to increase the speed of cars on motorways
