#A+BrarrAB#

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:

#2H_2+O_2rarr2H_2O#

#CaO+CO_2rarrCaCO_3#
