Question

Complete and balance the following equation:

Zn+ dil. H₂​SO₄​​ → ________

Answer 1

The complete balance equation is given below:

$\underset{\mathrm{zinc}}{\mathrm{Zn}\left(\mathrm{s}\right)}+\underset{\mathrm{dil}.\mathrm{sulphuric}\mathrm{acid}}{\mathrm{dil}{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)}\to \underset{\mathrm{zinc}\mathrm{sulphate}}{{\mathrm{ZnSO}}_4\left(\mathrm{aq}\right)}+\underset{\mathrm{hydrogen}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}$

• Zinc reacts with dilute sulphuric acid to produce hydrogen gas (H₂) and zinc sulphate solution.
• This is an example of a displacement reaction.
• The reaction is already balanced as the number of zinc, sulfur, oxygen and hydrogen atoms are equal on both reaction sides.
