        While they share the similarity of being made of more than one element, they are clear differences between compounds and mixtures. The main differences between them are as follows:<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n

        <\/div>\n<\/div>\n
        \n

        \n

        1 – The proportion <\/strong>or ratio of compound’s constituents<\/strong> (what they are made of) is fixed<\/strong>. <\/p>\n

        <\/p>\n

        For example water is a compound that is always consists of two hydrogen and one oxygen. By changing the proportion, it becomes a different compound, e.g. hydrogen peroxide consists of two hydrogen and two oxygen. <\/p>\n<\/div>\n<\/div>\n<\/div>\n

        \n
        \n
        \n

        2 – Compounds are <\/span>formed by a chemical reaction<\/strong>.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n

        \n
        \n
        \n

        3 – Compounds <\/span>cannot be broken down by physical methods<\/strong> but can be broken down using <\/span>electrolysis<\/strong>.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

        \n

        1 – The proportion <\/strong>or ratio of mixture’s constituents <\/strong>(what they are made of) is not fixed<\/strong>. <\/p>\n

        <\/p>\n

        For example sea water from Brunei and sea water from France are mixtures but the amount of water and the other salts will not be the same.<\/p>\n

        \n
        \n

        3 – Mixtures <\/span>can be broken down by physical methods <\/strong>such as filtration, evaporation, <\/span>distillation, chromatography, or using magnets.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n
