I thought equations were only used in Maths? 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

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

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.

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

Carbon dioxide + water Glucose + oxygen TRY… Green leaves during daylight turn carbon dioxide and water into glucose and oxygen. Carbon dioxide + water Glucose + oxygen Olive oil and sodium hydroxide react together to form soap and glycerol. Olive oil + sodium hydroxide soap + glycerol
