The cards Question What is a renewable resource? Tap to flip Answer A resource that will not run out, because it is regenerated or replaced within our lifetime. Question What is a finite resource? Tap to flip Answer A resource that exists in limited quantities on Earth and will run out with use, because it cannot be regenerated or replaced within our lifetime. Question What are synthetic products? Tap to flip Answer Products made by humans from natural resources, e.g. plastic or glass. Question What is sustainable development? Tap to flip Answer Meeting the needs of today's generation without compromising the ability of future generations to meet their own needs. Question Give one example of a sustainable development strategy. Tap to flip Answer e.g. using renewable resources, reusing products or recycling products. Question What is crude oil? Tap to flip Answer A fossil fuel formed over millions of years from dead plankton; a mixture of different hydrocarbons and impurities. Question What is a hydrocarbon? Tap to flip Answer A covalent compound containing hydrogen and carbon atoms only. Question What does a higher viscosity mean for how a liquid flows? Tap to flip Answer The higher the viscosity, the less easily the liquid flows. Question Fractional distillation separates miscible liquids or gases using which difference between them? Tap to flip Answer Their different boiling points. Question What is a fraction of crude oil? Tap to flip Answer A group of hydrocarbon molecules of similar size, separated from crude oil by fractional distillation. Question Most of the hydrocarbon molecules in crude oil are of which type? Tap to flip Answer Alkanes. Question How do smaller hydrocarbon molecules compare with larger ones in boiling point, flammability and viscosity? Tap to flip Answer Smaller molecules have lower boiling points, are more flammable and are less viscous. Question Give one example of a fraction of crude oil. Tap to flip Answer e.g. petroleum gases, petrol, kerosene, diesel oil, heavy fuel oil or bitumen. Question Does fractional distillation produce new substances from crude oil? Tap to flip Answer No. Crude oil is a mixture, and fractional distillation only separates its hydrocarbons by their boiling points. Question What is cracking? Tap to flip Answer A thermal decomposition reaction that breaks larger alkanes down into smaller alkanes and alkenes. Question Why are larger hydrocarbons cracked? Tap to flip Answer To produce smaller, more useful molecules. Question Why are alkanes described as saturated hydrocarbons? Tap to flip Answer They contain only single bonds between carbon atoms. Question What makes a compound unsaturated? Tap to flip Answer It contains at least one carbon-carbon double covalent bond. Question Give one method of cracking. Tap to flip Answer e.g. catalytic cracking or steam cracking. Question What colour change does bromine water show in the presence of an alkene? Tap to flip Answer It changes from orange/brown to colourless. Question How does cracking differ from fractional distillation? Tap to flip Answer Fractional distillation separates hydrocarbons by boiling point; cracking changes the molecular formula of compounds. Question What is a polymer? Tap to flip Answer A long-chained molecule formed by joining monomers together. Question What is a monomer? Tap to flip Answer A small molecule that can join with others to form a polymer. Question Are polymers giant structures? Tap to flip Answer No. Polymers are very large covalent molecules, not giant structures. Question Why are polymers solid at room temperature? Tap to flip Answer The intermolecular forces between polymer molecules are relatively strong. Question When you draw a polymer's repeating unit, what must you include on each side? Tap to flip Answer Open bonds, showing how the repeating units are bonded to each other. Question What does the reactivity series show? Tap to flip Answer Metals placed in order of reactivity, with the most reactive metal at the top. Question What is displacement? Tap to flip Answer When a more reactive element takes the place of a less reactive element in a compound. Question How does the ease of forming a positive ion relate to a metal's reactivity? Tap to flip Answer The more easily a metal atom forms a positive ion, the more reactive the metal is. Question When a metal reacts with an acid, what are the products? Tap to flip Answer A metal salt and hydrogen gas (not water). Question When a metal reacts with water, what are the products? Tap to flip Answer A metal hydroxide and hydrogen gas. Question Where is carbon often placed in the reactivity series? Tap to flip Answer Between aluminium and zinc. Question What is an ore? Tap to flip Answer A rock that contains metals or metal compounds, from which metal can be extracted. Question What is oxidation, in terms of oxygen and electrons? Tap to flip Answer A gain of oxygen or a loss of electrons. Question What is reduction, in terms of oxygen and electrons? Tap to flip Answer A loss of oxygen or a gain of electrons. Question What is a redox reaction? Tap to flip Answer A reaction in which both reduction and oxidation occur. Question In what form are unreactive metals often found in the earth? Tap to flip Answer As the pure metal. Question Which metals can be extracted by heating their oxides with carbon? Tap to flip Answer Metals that are less reactive than carbon. Question Why is a metal oxide said to be reduced when heated with carbon? Tap to flip Answer Because the metal oxide loses oxygen. Question Why is carbon said to be oxidised when it reacts with a metal oxide? Tap to flip Answer It gains oxygen, forming carbon dioxide. Question What does a life cycle assessment (LCA) measure? Tap to flip Answer The environmental impact of a product throughout its manufacture, use and disposal. Question Give one thing that can happen to a product at the end of its useful life. Tap to flip Answer e.g. it can be repaired, recycled, incinerated or thrown away. Question Why is it important to consider the vested interests of those reporting LCA findings? Tap to flip Answer Because LCAs are often subjective. Question Does an LCA measure only a product's carbon footprint? Tap to flip Answer No. It also includes things such as energy use, water use and pollutants released.

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.
