9/18/2021 Reactions of metals with oxygen When a metal reacts with oxygen it will form a METAL OXIDE. This is what happens when a metal rusts. We can make this reaction happen quicker by burning the metal. METAL + OXYGEN METAL OXIDE Copy and complete the following reactions: 1) Magnesium + oxygen 2) Copper + oxygen 3) Calcium + oxygen 4) Iron + oxygen

9/18/2021 Reactions of metals with water When a metal reacts with water hydrogen is always given off. The other product will be either a metal hydroxide or a metal oxide. METAL + WATER METAL OXIDE + HYDROGEN METAL HYDROXIDE + HYDROGEN Copy and complete the following reactions: 1) Sodium + water 2) Potassium + water 3) Calcium + water 4) Iron + steam

9/18/2021 Reactions of metals with acids When a metal reacts with an acid it gives off hydrogen (which can be “popped” using a lit splint). The other product is a salt. METAL + ACID e. g. magnesium + hydrochloric acid SALT + HYDROGEN magnesium chloride + hydrogen Copy and complete the following reactions: 1) Calcium + hydrochloric acid 2) Zinc + hydrochloric acid 3) Iron + hydrochloric acid 4) Lithium + sulphuric acid

9/18/2021 Complete the following reactions: 1) Lithium + water Lithium hydroxide + hydrogen 2) Lithium + hydrochloric acid Lithium chloride + hydrogen 3) Silver + oxygen Silver oxide 4) Magnesium + sulphuric acid Magnesium sulphate + hydrogen 5) Potassium + oxygen Potassium oxide 6) Aluminium + oxygen Aluminium oxide 7) Manganese + water Manganese oxide + hydrogen 8) Sodium + sulphuric acid Sodium sulphate + hydrogen 9) Lithium + oxygen Lithium oxide 10) Nickel + hydrochloric acid Nickel chloride + hydrogen
