Chemical Reactions
What you should know.
- A manufacturing process
changes raw material into a useful product.
- A change which makes a
new substance is a chemical change (reaction).
- Things which can happen
when a chemical reaction takes place.
- The blast furnace gets
iron from iron ore.
- Reduce means take oxygen
away.
- Burning is a chemical
reaction. It is also called combustion.
- When a fuel burns in air
it makes oxides.
- Exothermic reactions give
out heat (energy).
- Oxidation happens when
substances gain oxygen.
- Respiration is an
exothermic reaction.
- Yeast is used to make
alcohol.
- Fermentation is a process
used to make alcohol.
- It is dangerous to drink
and drive.
- Air and water are needed
for iron to rust.
- Salt speeds up rusting.
- Rusting is an oxidation
reaction.
- Virtually all materials
are made through chemical reactions.
- Some chemical reactions,
e.g. rusting, are not useful.
- Acid rain affects the
environment.
What you should be able to
do.
- List 4 substance we get
from crude oil.
- Observe whether a
chemical reaction is taking place.
- List the properties of
iron.

- Collect a gas over water.
- Plan an investigation to
see which carbonate changes fastest.
- Draw and label a fire
triangle.
- Burn a fuel safely.
- Discuss the similarities
between respiration and burning.
- Make a sample of alcohol.
- Write a word equation for
fermentation.
- Plan an investigation on
rusting.
