Question

Balance the following equation: CuSO4 (aq) + K2Cr2O7 (aq) -->

Please explain the answer

Answer 1

Answer #1

The balanced reaction is

CuSO4 + K2Cr2O7 = CuCr2O7 + K2SO4

It is a double replacement reaction.

To balance the reaction make sure the number of atoms of different elements in the reactants side is equal to that in products side .

Here copper is 1 on left , so must be 1 on right too.

Likewise sulfur 1 on left , and 1 on right

Potassium 2 atoms on left, so 2 atoms on right

Then oxygen is 11 on left side, so 11 on right side too

Chromium has 4 atoms on left so must be 4 on right too
