Making Compounds Test Burning magnesium Heating Copper carbonate Magnesium + hydrochloric acid Potassium iodide + lead nitrate Observations Before After

Making Compounds Burning Magnesium. Burn a small piece of magnesium ribbon in a blue Bunsen flame.

Making Compounds Heating Copper carbonate. Add 2 spatulas of copper carbonate to a boiling tube. Heat strongly over a Bunsen.

Making Compounds Potassium iodide mixed with lead nitrate. Place 5 ml of one solution into a test tube, and 5 ml of the other solution into another test tube. Mix, then filter the resulting mixture.

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

Making a Compound: Combustion Joining an element with oxygen is called combustion. How do you know a chemical reaction has taken place?

Naming compounds When elements react they produce a compound What are elements?

Naming compounds The 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
