Consider the following chemical reaction:
jolli1 [7]

From the calculation, the moles of water produced is 18 moles of water.

<h3>What is a decomposition reaction?</h3>

A decomposition reaction is one in which a substance is split up into smaller parts.

We have the reaction; 2 Cr(OH)3(aq) ------------> Cr2O3(s) + 3H2O(l)

From this reaction;

2 moles of  Cr(OH)3 produced 3 moles of water

12 moles of  Cr(OH)3 will produce;

12 moles  *  3 moles / 2moles

= 18 moles of water

Hence, 12 moles of chromium (III) hydroxide produces 18 moles of water.
