All 5 cards in this deck

What are the products of the complete combustion of a hydrocarbon?: Carbon dioxide and water.
Energy is given out.
Why does incomplete combustion of a hydrocarbon occur?: A limited supply of oxygen.
Which two extra products can be formed by the incomplete combustion of a hydrocarbon?: Carbon (soot) and carbon monoxide.
How does carbon monoxide act as a toxic gas?: It binds to haemoglobin in red blood cells, so the blood carries less oxygen.
Give two problems caused by incomplete combustion in appliances such as gas boilers.: Carbon monoxide is toxic and can kill (it has no smell or colour); soot blackens surfaces, blocks pipes and can cause fires.
