Reactivity Series Flashcards
What gas causes acid rain?
Sulphur dioxide
What is oxidation?
The gain of oxygen by a substance
Example of oxidation
Magnesium+oxygen->magnesium oxide
What is reduction
The loss of oxygen from a substance
Example of reduction
Copper oxide + hydjrogen -> copper + water
What three things are needed to start a fire
Oxygen
Heat
Fuel
What is complete combustion
When a fuel burns with plenty of air
What is incomplete combustion
When the supply of air is poor
What is produced from combustion
Carbon dioxide
What is produced from incomplete co,bastion
Carbon monoxide
Carbon
What is thermal decomposition
Same comping break down when heated, forming two or more products from one reactant
Example of thermal decomposition
Copper carbonate -> copper oxide + carbon dioxide
What is a catalyst (3)
Speeds up reactions
Is not used up during the reaction
Stays chemically unchanged
Example of catalyst
Exhaust systems of cars (help reduce the release of toxic gases)
Reactions in catalyst is converters
Covert carbon monoxide into carbon dioxide
Convert nitrogen oxides into nitrogen and oxygen
