# What kind of reaction is represented by H_2O + ZnO -> Zn(OH)_2?

Jul 25, 2016

This is a synthesis reaction, also called a combination reaction.

#### Explanation:

A synthesis reaction occurs when two or more reactants produce a single product. The general equation is A+B$\rightarrow$C.

In your question, the reactants (A and B) are water and zinc oxide, and the product (C) is zinc hydroxide.

Note: I don't believe that the reaction in your question actually occurs, but the equation in your question is set up as a synthesis reaction.

To denote a reaction that does not occur, you would write A+B$\rightarrow$no reaction
