==Key Stage 3==
===Meaning===
[[Thermal Decomposition]] is a type of [[Chemical Reaction|chemical reaction]] in which a large [[compound]] is broken down into smaller [[molecule]]s due to high [[temperature]]s.
===About Thermal Decomposition===
: When [[material]]s are heated the [[particle]]s inside [[vibrate]] and move more quickly, colliding with one another. For large [[molecule]]s this can cause them to [[collide]] with enough [[force]] to break the [[molecule]] apart into smaller [[molecule]]s. This is '''thermal decomposition'''.
: '''Thermal Decomposition''' happens to certain types of [[compound]] more than others. At this stage the '''thermal decompositions''' you should know have the general [[Chemical Equation|equation]]: Metal Carbonate → Metal Oxide + Carbon Dioxide
===Examples===
'''Metal Carbonate → Metal Oxide + Carbon Dioxide'''
: Calcium Carbonate → Calcium Oxide + Carbon Dioxide
: Copper Carbonate → Copper Oxide + Carbon Dioxide
: Zinc Carbonate → Zinc Oxide + Carbon Dioxide
