Question

directions: drag a coefficient to each box. each box must have a coefficient. each coefficient may be used more than one time. use the lowest possible coefficients to balance this chemical equation. al + niso₄ → ni + al₂(so₄)₃

Explanation:

Step1: Balance the sulfate ions

In \(NiSO_4\) and \(Al_2(SO_4)_3\), to balance the sulfate \((SO_4)\) ions, since there are 3 sulfate ions in \(Al_2(SO_4)_3\) and 1 in \(NiSO_4\), we put a coefficient of 3 in front of \(NiSO_4\).

Step2: Balance the nickel atoms

After putting a 3 in front of \(NiSO_4\), there are 3 nickel \((Ni)\) atoms on the left - hand side. So we put a coefficient of 3 in front of \(Ni\) on the right - hand side.

Step3: Balance the aluminum atoms

There are 2 aluminum \((Al)\) atoms in \(Al_2(SO_4)_3\). So we put a coefficient of 2 in front of \(Al\) on the left - hand side.

The balanced equation is \(2Al + 3NiSO_4=3Ni + 1Al_2(SO_4)_3\)

Answer:

2, 3, 3, 1
