1) When a metallic element reacts with a non-metallic element, a compound is produced. The name of the compound contains the name of the metal and the changed name of the non-metal.
metal+non-metal ---- metal non-metalIDE iron + sulphur ------- iron sulphIDE
2) When an alkali metal reacts with water, a soluble base (an alkali) and hydrogen are produced. alkali alkali metal + water ----------metal hydroxide + hydrogen lithium + water -------- lithium hydroxide + hydrogen
The hydroxide produced depends on the metal used.
3) When an alkali metal reacts with oxygen in air, an oxide is produced:
alkali metal + oxygen (in air) ------metal oxide sodium + oxygen ------sodium oxide
The oxide produced depends on the metal used.
4) When an acid reacts with an alkali, a salt and water is produced:
acid (ph 1-6.5) + alkali (ph 7.5-14) ------------------salt + water hydrochloric acid + potassium hydroxide ------potassium chloride + water
The salt that is produced depends upon which acid and alkali react.
5) When an acid reacts with a metal carbonate, a salt, water and carbon dioxide are produced:
acid + metal carbonate ------- salt + water + carbon dioxide nitric acid + calcium carbonate ------- calcium nitrate + water + carbon dioxide The salt that is produced depends upon which acid and metal react. 6) When an acid reacts with metal, a salt and hydrogen are produced: acid + metal --------------- salt + hydrogen sulphuric acid + magnesium ------- magnesium sulphate + hydrogen
The salt that is produced depends upon which acid and which metal react.
