The cards Question Where are the transition metals placed in the periodic table? Tap to flip Answer In the block between Groups 2 and 3. Question How do the melting points of transition metals generally compare with those of Group 1 metals? Tap to flip Answer Transition metals generally have higher melting points. Question How does the density of transition metals generally compare with that of Group 1 metals? Tap to flip Answer Transition metals are generally more dense. Question How do transition metals react with water? Tap to flip Answer Slowly, or not at all. Question Are all metals equally good catalysts for a given reaction? Tap to flip Answer No. Each reaction is catalysed best by one catalyst. Question Can a transition metal form ions with more than one charge? Tap to flip Answer Yes. Transition metals can form ions with different charges. Question What appearance do compounds of transition metals often have? Tap to flip Answer They are often vibrantly coloured. Question What is rusting? Tap to flip Answer The corrosion of iron or steel in the presence of water and oxygen. Question What is corrosion? Tap to flip Answer The gradual deterioration of a substance as it reacts with substances in its environment, e.g. a metal oxidising in air. Question What is sacrificial protection? Tap to flip Answer Using a more reactive metal that corrodes in preference, so that another metal is protected from corrosion. Question Which metal is used to galvanise, giving sacrificial protection? Tap to flip Answer Zinc. Question What is electroplating? Tap to flip Answer Using electricity to deposit a thin layer of metal onto the surface of another conductive object. Question Give one reason for electroplating a metal object. Tap to flip Answer To improve its appearance or its resistance to corrosion. Question When can a metal oxide layer protect the metal underneath it? Tap to flip Answer When the oxide forms a physical barrier. Question Which arrow shows that a chemical reaction is reversible? Tap to flip Answer The double-headed arrow, ⇌. Question What colour is hydrated copper sulfate? Tap to flip Answer Blue. Question What colour is anhydrous copper sulfate? Tap to flip Answer White. Question What does a dot in the formula of a hydrated salt, as in CuSO₄·5H₂O, show? Tap to flip Answer That the salt contains water molecules within its crystal structure. Question Ammonium chloride breaks down reversibly into which two substances? Tap to flip Answer Ammonia and hydrogen chloride. Question Can the forward and backward reactions of a reversible reaction happen at the same time? Tap to flip Answer Yes, if the conditions allow it. Question What is dynamic equilibrium? Tap to flip Answer The state in a closed system when the forward and backward reactions of a reversible reaction occur at the same rate, so concentrations stay constant. Question Are the amounts of reactants and products equal at equilibrium? Tap to flip Answer Not necessarily. They stay constant, but they need not be equal. Question In what kind of system can equilibrium occur? Tap to flip Answer Only in a closed system. Question What is a closed system? Tap to flip Answer One that matter cannot enter or leave; only energy can transfer between it and its surroundings. Question What does the Haber process produce? Tap to flip Answer Ammonia, from nitrogen and hydrogen. Question Which gas makes up most of natural gas? Tap to flip Answer Methane. Question From what is the hydrogen for ammonia production made? Tap to flip Answer From natural gas and steam. Question What catalyst is used in the Haber process? Tap to flip Answer Iron. Question At what temperature is the Haber process typically run in industry? Tap to flip Answer 400–450 °C. Question At what pressure is the Haber process typically run in industry? Tap to flip Answer 150–300 atmospheres. Question Why is ammonia continuously removed in the Haber process? Tap to flip Answer Otherwise the equilibrium shifts back towards the reactants, reducing the yield. Question How is percentage yield calculated? Tap to flip Answer Actual yield divided by theoretical yield, as a percentage. Question What is atom economy? Tap to flip Answer The percentage, by relative mass, of reactants that are converted into useful products. Question Which industrial process produces sulfuric acid? Tap to flip Answer The Contact process. Question What does 'equilibrium position' refer to? Tap to flip Answer The relative concentrations of reactants and products in a reversible reaction at equilibrium. Question How can a high temperature affect the yield of an exothermic reversible reaction? Tap to flip Answer It can decrease the yield, by shifting the equilibrium towards the reactants. Question What is the formula of ammonia? Tap to flip Answer NH₃. Question What does ammonia gas do to moist red litmus paper? Tap to flip Answer Turns it blue. Question What forms when ammonia reacts with hydrogen chloride? Tap to flip Answer White fumes of ammonium chloride. Question Compounds of which three elements do fertilisers contain to promote plant growth? Tap to flip Answer Nitrogen, phosphorus and potassium. Question What is eutrophication? Tap to flip Answer Nutrients building up in bodies of water, increasing the growth of microorganisms that reduce oxygen in the water. Question What is a batch process? Tap to flip Answer A manufacturing method made up of discrete stages, rather than constant production. Question What is a continuous process? Tap to flip Answer A manufacturing method in which the product is constantly produced. Question Give one product that ammonia is a feedstock for. Tap to flip Answer E.g. fertilisers, explosives, plastics, dyes or cleaning products. Question What is a composite material? Tap to flip Answer A mixture of a matrix and a reinforcement, combined to give a material with properties of both.

How this deck was checked On 2026-11-02, every card was compared with its source: the lessons of Oak National Academy, a public body funded by England's Department for Education that publishes lessons for the national curriculum. Because the cards come from those lessons, no second source was sought. The comparison was done automatically, not by a teacher, so a card can still be wrong.
