What is the basic formula of a synthesis reaction?

Dec 21, 2016

$A + B \rightarrow A B$

Explanation:

It is common to represent two reacting elements or compounds as A and B. These could be anything formula from a single atom to a large molecule.

In a synthesis reaction, two (or more) substances join together to form a single substance, which we write as AB. By writing the letters together (with no + sign between them) we mean they have bonded together to make one substance.

Here are a couple of examples:

$2 {H}_{2} + {O}_{2} \rightarrow 2 {H}_{2} O$

$C a O + C {O}_{2} \rightarrow C a C {O}_{3}$
