Combustion Flashcards
Combustion
a reaction in which a substance reacts with oxygen, releasing energy in the form of light and heat
What does combustion usually result in
burning or explosion
Complete combustion
when all the oxygen in reactions are used up
Why are fuels combustion reactions
they have enough oxygen to make carbon dioxide.
what does the release of carbon dioxide do
adds to the
greenhouse effect and global warming
combustion reaction equation
fuel + oxygen 🡪 carbon dioxide + water
Incomplete combustion
When the air supply is limited, carbon monoxide can be produced instead of
carbon dioxide.
Incomplete combustion equation
Fuel + limited oxygen 🡪 carbon monoxide+carbon+water
How is carbon released in an incomplete combustion reaction
as a soot(black powder)
How does carbon monoxide affect humans
poisonous
products of a complete combustion
Carbon dioxide and water
products of an incomplete combustion
Carbon monoxide + carbon + water
hydrocarbon
type of compound that combust extremely well.
hydrocarbon examples
Coal, petrol, natural gas
how are exothermic reactions related to combustion reactions
both reactions release heat
why do some fires produce smoke
when there is an incomplete combustion(not enough oxygen to burn the fuel completely)
example of complete combustion
Burning candle wax
example of an incomplete combustion
burning paper
corrosive
the ability of a substance to destroy every material it comes in contact with
concentration
measure of the amount pf hydrogen ions in an acid or hydrozide ions in a base
