Polyesters are a type of condensation polymer. They can be made by reacting a dicarboxylic acid with a diol.

Figure 1 shows a simplified representation of the repeating unit of a polyester chain.

A schematic of a polyester repeating unit: an open bond connects to an oxygen atom, then a rectangular block representing the diol residue, then an oxygen atom, which is connected to a carbonyl group (C=O), then a circular block representing the dicarboxylic acid residue, then another carbonyl group (C=O), ending with an open bond. The whole structure is enclosed in square brackets with a subscript n.

Give the chemical formula of the other substance produced in this condensation polymerisation reaction.
