WebA lot of metals used day-to-day are alloys. This means that they are a mixture of two or more metals. GCSE Chemistry – Metal Alloys Alloys have different properties. Since alloys are mixtures of metals, this means that they will have different properties depending on the metals that they contain. WebWhen a metal reacts with acid, it produces a salt and hydrogen gas. The more reactive the metal, the more hydrogen gas is produced per second. Therefore the more reactive the …

WebMetals that are placed high on the reactivity series such as potassium and sodium are very dangerous and react explosively with acids When acids react with metals they form a salt and hydrogen gas: The general equation is: metal + acid salt + hydrogen Some examples of metal-acid reactions and their equations are given below: WebSome very reactive metals, such as calcium and potassium can react with water to form a metal hydroxide and hydrogen. Metals that are lower down on the reactivity series, such as zinc, iron, lead and copper won’t react with water. This is why it’s safe to have copper water pipes!

WebExtraction of Metals (GCSE Chemistry) Extraction of Metals from their Ores Metals are found in the earth as ores. In the earth, metals are not found as ‘pure metals’. Instead, they are found as metal ores, which are oxidised metals. Unreactive metals are found in the earth’s crust as uncombined metals. Metals must be extracted from their ores.

WebMetals react with oxygen. When metals are in the presence of oxygen, they gain oxygen, forming substances called metal oxides. For example, when we react iron with oxygen, we can form iron (III) oxide. This is the equation: 4Fe + 3O 2 → 2Fe 2 O 3 Iron + Oxygen → Iron (III) oxide These reactions are oxidation reactions.
