Reactivity series of metals an order of reactivity, giving the most reactive metal first, based on results from a range of experiments involving metals reacting with oxygen, water, dilute hydrochloric acid and metal salt solutions Extraction of metals Most reactive metals are extracted from their ores by electrolysis of a molten compound. Iron ore blast furnace Fe2O3 + 3CO → 2Fe + 3CO2 - Carbon is higher in the reactivity series than iron and is therefore able to remove the oxygen from ...

AQA GCSE Chemistry What is a mixture? - ANS Two or more elements not chemically bonded What is the difference between a compound and a mixture? - ANS Compounds have a fixed composition whereas mixtures do not. Mixtures are not chemically bonded but compounds are. Describe the process of filtration - ANS Pour the mixture onto the filter paper, the liquid simply passes through the filter paper into the flask. The insoluble solid cannot pass through and so it stays on the paper...
