(Quizs) KS3 Yr 7 Reactions

Conduct

• The ability of a material to allow the flow of energy or electricity.

• The process of combining different materials to create a new one.

• The measure of how much energy a material can store.

• The ability of a material to resist the flow of energy or electricity.

Metal

• A substance that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity.

• A soft, non-malleable substance that is a poor conductor of heat and electricity.

• A liquid at room temperature that is highly reactive and corrosive.

• A solid that is brittle and lacks luster, often used as an insulator.

Sonorous

• A property of a material that allows it to produce a deep or ringing sound when struck.

• A characteristic of a material that makes it lightweight and easy to handle.

• A quality of a material that prevents sound from passing through it.

• A feature of a material that makes it resistant to heat.

Metal + Acid Reaction

• A chemical reaction where a metal reacts with an acid to produce a salt and hydrogen gas.

• A process where metals are oxidized without any acid involvement.

• A reaction that only occurs with non-metal substances.

• A method to create electricity using metals and acids.

Acid

• A substance that donates hydrogen ions and typically has a pH less than 7.

• A substance that accepts hydrogen ions and typically has a pH greater than 7.

• A neutral substance with a pH of 7.

• A substance that increases the concentration of hydroxide ions in a solution.

Metal Oxidation Reaction

• A reaction where a metal reacts with oxygen to form an oxide.

• A reaction where a metal combines with another metal to form an alloy.

• A reaction where a metal is reduced by a non-metal.

• A reaction where a metal dissolves in acid to produce hydrogen gas.

Ductile

• A property of a material that allows it to be drawn out into a thin wire.

• A characteristic of a material that makes it resistant to deformation.

• A measure of a material's ability to conduct electricity.

• A term used to describe materials that are brittle and break easily.

Indicator

• A substance that changes color to indicate the presence of an acid or a base.

• A type of chemical that neutralizes acids.

• A solution that has a pH of 7.

• A compound that increases the temperature of a solution.

Metal Displacement Reaction

• A reaction where a more reactive metal displaces a less reactive metal from its compound.

• A reaction where two metals combine to form a new compound.

• A reaction that occurs only in the presence of water.

• A reaction that involves the oxidation of a metal without any displacement.

Alkaline

• A substance that has a pH greater than 7 and can neutralize acids.

• A substance that has a pH less than 7 and can neutralize bases.

• A substance that has a pH of exactly 7 and is neutral.

• A substance that is always a solid at room temperature.
