Type of Reaction for Cu(OH)2 = CuO + H2O

In this video we determine the type of chemical reaction for the equation Cu(OH)2 = CuO + H2O (Copper (II) hydroxide ).

Since we one substance breaking apart into two (or more) substances, Cu(OH)2 = CuO + H2O is a decomposition reaction. Decomposition reactions follow the general form of:

AB → A + B

An example of a decomposition reaction is CaCO3 = CaO + CO2 .

There is no specific number of products in a decomposition reaction.

--Type of Reactions--

Synthesis (Combination): A + B → AB
Decomposition: AB → A + B
Single Replacement : A + BC → B + AC
Double Replacement: AB + CD → AD + BC
Combustion: CxHy + O2 → CO2 + H2O
Neutralization: HX + MOH → MX + H2O
Reduction-Oxidation (Redox): Electrons are exchanged. Many of the above reactions are redox.
Endothermic and Exothermic: Reactions that take in (endo) or give off heat (exo).
It is not necessary to balance Cu(OH)2 = CuO + H2O in order to determine the type of reaction, although it makes more sense with the equation is balanced.

Being able to determine the type of reaction by looking at reactants can help in predicting the outcome of the chemical reaction.
