Burning magnesium

Heating Copper carbonate

Magnesium + hydrochloric acid

Potassium iodide + lead nitrate

Making Compounds

Burning Magnesium.Burn a small piece of magnesium ribbon in a

blue Bunsen flame.

Making CompoundsHeating Copper carbonate.

Add 2 spatulas of copper carbonate to a boiling tube. Heat strongly over a Bunsen.

Making CompoundsPotassium iodide mixed with lead nitrate.

Place 5ml of one solution into a test tube, and 5ml of the other solution into another test tube.

Mix, then filter the resulting mixture.

Making CompoundsMagnesium and hydrochloric acid

Add 10ml of hydrochloric acid to a boiling tube, then drop in a piece of magnesium ribbon.

Making a Compound: CombustionJoining an element with oxygen is called

combustion.

How do you know a chemical reaction has taken place?

Naming compoundsWhen elements react they produce a compound

What are elements?

Naming compoundsThe Rules

1. The names of the elements are written from left to right as they appear on the periodic table e.g. Sodium chloride

2. If there are only 2 elements forming the compound then the ending of the second name is “ide” e.g. Copper and sulphur is called copper sulphide

3. If the compound contains oxygen and 2 other elements the ending of the second name is usually “ate” e.g. Copper, sulphur and oxygen is called copper sulphate
