The cards Question Are metals good or poor conductors of electricity? Tap to flip Answer Good: metals are good thermal and electrical conductors. Question Which two words describe a ceramic material? Tap to flip Answer Hard and brittle. Question How do ceramics become hard? Tap to flip Answer They are made from soft substances that become hard and brittle when heated. Question What are plastics made from? Tap to flip Answer Polymers. Question What is a polymer? Tap to flip Answer Long-chained molecules formed by joining together monomers. Question What is an alloy? Tap to flip Answer A mixture of two or more elements, at least one of which is a metal. Question Is an alloy a mixture or a compound? Tap to flip Answer A mixture. Question What is a composite material? Tap to flip Answer A material made by combining two or more different types of material, creating a new material with improved properties. Question What are the small molecules that join together to form polymers called? Tap to flip Answer Monomers. Question Why do some polymers have high melting points? Tap to flip Answer Because their molecules are hard to separate. Question Are all polymers synthetic? Tap to flip Answer No: polymers can be made synthetically, but some also exist naturally. Question What does a plasticiser do to a polymer? Tap to flip Answer It gets between the polymer molecules so they move over each other more easily, increasing flexibility. Question What is a cross-link in a polymer? Tap to flip Answer A chemical bond between different chains of atoms. Question How can cross-links change a polymer's properties? Tap to flip Answer They can make it harder and less flexible. Question What do some metals produce when they react with water? Tap to flip Answer A metal hydroxide and hydrogen gas. Question What do some metals form when they react with oxygen? Tap to flip Answer A metal oxide. Question What does the reactivity series for metals show? Tap to flip Answer Metals in order of reactivity, with the most reactive metal at the top. Question What does a higher position in the reactivity series tell you about a metal? Tap to flip Answer It is likely to react more vigorously. Question What is an exothermic reaction? Tap to flip Answer A reaction in which energy is transferred from the reactants to the surroundings. Question Do metals less reactive than hydrogen react with acid? Tap to flip Answer No. Question What is a displacement reaction? Tap to flip Answer A reaction in which a more reactive element takes the place of a less reactive element in a compound. Question What forms when magnesium reacts with copper sulfate solution? Tap to flip Answer Magnesium sulfate solution and copper. Question When can one metal displace another metal from its salt in solution? Tap to flip Answer When it is more reactive than the other metal. Question How can displacement reactions be used with the reactivity series? Tap to flip Answer To confirm the position of a metal in the reactivity series. Question What is an ore? Tap to flip Answer A rock that contains metals or metal compounds, from which metal can be extracted. Question When can carbon be used to extract a metal from its ore? Tap to flip Answer When carbon is more reactive than the metal. Question What is a catalyst? Tap to flip Answer A chemical that speeds up a reaction without being used up or chemically changed. Question Can one catalyst be used for every reaction? Tap to flip Answer No: catalysts are specific, and different reactions need different catalysts. Question What is an enzyme? Tap to flip Answer A biological catalyst that speeds up reactions in living cells. Question Does a reaction still happen without its catalyst? Tap to flip Answer Yes, but at a very slow rate.

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. Flash Feed is not affiliated with any source named here.
