8Eb/8Ec Oxidation and Fire Safety

What is a fire triangle?

• A way of showing in a diagram that heat, fuel and oxygen are needed for fire.

• Changes that will happen to patterns of weather as a result of global warming.

• A warning symbol that shows why something is dangerous.

• Something that is used to put out a fire, such as a canister of carbon dioxide, powder, water or foam.

What is a fire extinguisher?

• A reaction that gives out energy that can be felt as it heats the surroundings, such as combustion.

• Something that is used to put out a fire, such as a canister of carbon dioxide, powder, water or foam.

• Anything, such as cloth, paper or a layer of sand, through which a fluid is passed to remove suspended pieces of solid.

• Something that only lets certain colours through and absorbs the rest.

What is oxidation?

• Something that is used to put out a fire, such as a canister of carbon dioxide, powder, water or foam.

• Rainwater that is more acidic than usual due to air pollution, usually caused by sulfur dioxide and nitrogen oxides dissolved in it.

• A substance that scientists once thought explained why things burn; it has since been proved that it does not exist.

• Reacting with oxygen. For example, when a fuel combusts or when a metal reacts with oxygen to form a metal oxide.

What is an oxide?

• A substance that supplies oxygen for a reaction.

• Any element that is not shiny and does not conduct heat and electricity well.

• A compound of a metal or non-metal with oxygen, such as magnesium oxide or carbon dioxide.

• A form of carbon, which is produced as very fine particles when hydrocarbon fuels undergo incomplete combustion.

Any element that is shiny when polished, conducts heat and electricity well, is malleable and flexible and often has a high melting point.

• Oxide

• Metal

• Fuel

• Exothermic

What is a metal oxide?

• A metal that has combined with oxygen in a chemical reaction, e.g. magnesium oxide.

• Rainwater that is more acidic than usual due to air pollution, usually caused by sulfur dioxide and nitrogen oxides dissolved in it.

• Any element that is shiny when polished, conducts heat and electricity well, is malleable and flexible and often has a high melting point.

• Acidic gas formed when nitrogen reacts with oxygen at high temperatures, such as in a car engine. There are different types of nitrogen oxide.

What is a non-metal?

• A substance that can harm the environment or the organisms that live there.

• A substance that can harm the environment or the organisms that live there.

• Any element that is not shiny and does not conduct heat and electricity well.

• Any element that is shiny when polished, conducts heat and electricity well, is malleable and flexible and often has a high melting point.

What is phlogiston?

• A substance that supplies oxygen for a reaction.

• Reacting with oxygen. For example, when a fuel combusts or when a metal reacts with oxygen to form a metal oxide.

• The substances that are formed in a chemical reaction

• A substance that scientists once thought explained why things burn; it has since been proved that it does not exist.
