# Problem: Balance the following equations1. (NH4)2Cr2O7 (aq) -&gt; NH3 (aq) + H2O (l) + Cr2O3 (s) + O2 (g)

###### FREE Expert Solution

We’re being asked to balance the given equations.

Recall that when balancing chemical equations, we have to make sure that the number of elements on both sides is equal with the lowest whole number coefficients.

Reaction:

 (NH4)2Cr2O7 (aq) → NH3 (aq) + H2O (l) + Cr2O3 (s) + O2 (g) N            2H            8Cr          2O           7 N            1H            3 + 2 = 5Cr          2O           1 + 3 + 2 = 6
