What type of reaction occurs when complex compounds are broken down into simpler substances?

Answer 1

Decomposition reaction

A decomposition reaction is a reaction where complex compounds or molecules are broken down into simpler molecules. Usually, these reactions take a lot of activation energy to start the reaction, and that energy takes in the form of heat, thus making the reaction endothermic.

An example would be the thermal decomposition of limestone (calcium carbonate). The reaction for that is:

#CaCO_3(s)stackrel(Delta)->CaO(s)+CO_2(g)uarr#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
