What is the reactivity series
List of metals arranged from most reactive
What is a displacement reaction
reaction where a more reactive element takes the place of a less reactive element in a compound
What is an ore
A mineral that contains enough metal to extract economically
What is rusting
Where iron reacts with oxygen in the presence of water to form iron oxide
Give one way rusting can be prevented
Painting, Greasing, Galvanising , making an alloy, coating in plastic , sacrificial protection
What is an alloy
A mixture of metals
What is an exothermic reaction
A reaction where heat energy is released causing the surroundings to heat up
What is combustion
When fuel burns in oxygen to release energy in the form of heat
what is the word equation for complete Combustion of a hydrocarbon fuel
Fuel+ Oxygen->carbon dioxide+Water
what is the word equation for incomplete combustion for a hydrocarbon fuel
Fuel+oxygen->carbon monoxide+ water
Why is carbon dioxide a problem
Increases global warming which leads to climate change
Where is lipase produces
small intestines, pancrease
