Chemical Changes

Carbon dioxide

and Water are produced.

Alkali

- substance that dissolves in water and dissociates (break up) to give hydroxide ions (OH)- which is responsible for the properties of a(n) .

Acids

- substance that dissolves in water and dissociates (break up) to give hydrogen ions (h+) which is responsible for the properties of a(n) .

Charcoal

(carbon) in a barbecue pit burns in oxygen to form carbon dioxide.

Copper

(II) carbonate is heated to form (II) oxide and carbon dioxide.

Combustion of methane

gas (natural) to generate electricity in power plants which forms carbon dioxide and water- If combustion is incomplete, produces carbon monoxide, carbon dioxide and water.

Hydrochloric acid

(acid) reacts with sodium hydroxide (alkali) to form sodium chloride and water.

Acids

substance that dissolves in water and dissociates (break up) to give hydrogen ions (h+) which is responsible for the properties of an acid

Alkali

substance that dissolves in water and dissociates (break up) to give hydroxide ions (OH-) which is responsible for the properties of an alkali
