        Word Definition Topic
        base A substance with a pH higher than 7, and which has a high concentration of hydroxyl ions. Bases react with acids to form a salt and water (called neutralisation). Metal hydroxides, oxides and carbonates are all bases. Useful products from air
        catalyst A catalyst changes the rate of a chemical reaction without being changed by the reaction itself. Useful products from air
        compound A compound is a substance formed by the chemical union (involving bond formation) of two or more elements. Useful products from air
        cracking Cracking is the breaking down of large hydrocarbon molecules into smaller, more useful hydrocarbon molecules by vapourizing them and passing them over a hot catalyst. Useful products from air
        equilibrium If the rate of the forward reaction and the rate of the back reaction in a reversible reaction are equal, the reaction is in equilibrium. Useful products from air
        eutrophication Eutrophication is the enrichment of a water body with nutrients - such as nitrates - which results in excessive growth of algae and other aquatic plants, leading to depletion of oxygen. Useful products from air
        exothermic Heat energy is released in an exothermic reaction. We know this because the surroundings get warm. Useful products from air
        liquefy To liquefy means to become liquid, for example through heating a solid or cooling a gas. Useful products from air
        molecule A molecule is a collection of two or more atoms held together by chemical bonds. It is the smallest part of a substance that displays the properties of the substance. Useful products from air
        neutralisation Neutralisation is the reaction between an acid and a base to form a salt plus water. Useful products from air
        oxidation Oxidation is a reaction in which oxygen combines with a substance. Oxidation also means a loss of electrons. Useful products from air
        product A product is a substance formed in a chemical reaction. Useful products from air
        reactant A reactant is a substance put together with another substance/substances to undergo a chemical reaction. Useful products from air
        reversible reactions Reversible reactions are chemical reactions which can go both ways. The direction of the reaction depends on the condition of the reactants. Useful products from air
