Chemical Equations
These are what chemists use to describe a chemical reaction
Three types of chemical equation:
WORD EQUATION
FORMULA EQUATION
I thought equations were only used in Maths?
BALANCED EQUATION

2. Chemicals which are Formed
REACTANTS PRODUCTS
Chemicals which React
Chemicals which are Formed
Means “Changes into”
Chemical names can be on two lines to make the whole equation fit from left to right across the page

3. In the flame methane and oxygen change into carbon dioxide and water
WORD EQUATIONS
In the flame methane and oxygen change into carbon dioxide and water
Methane + Oxygen Water + Carbon dioxide
Methane and oxygen are the reactants. They must go on the left.
Water and carbon dioxide are the products. They must go on the right.

4. Kerosine + oxygen carbon dioxide + water
In a plane engine kerosine and oxygen change into carbon dioxide and water.
Kerosine + oxygen carbon dioxide + water
REACTANTS
PRODUCTS

5. Carbon dioxide + water Glucose + oxygen
