Develop a model to show the chemical potential energy of wood and how that energy is transformed.

Explanation:

Chemical potential energy is the chemical energy stored (or property) of a substance. One chemical potential energy of wood is combustion. Combustion involves the burning of a substance in excess oxygen (in this case open air). The chemical energy stored here is transformed to thermal/heat energy after combustion due to the large amount of heat evolved/produced.

NOTE:

The model above also that combustion is an exothermic reaction because it involves the release of heat into it's surrounding.

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

hope this : -)
