Question

Mg + H²SO⁴ = Mgso⁴ + H² which reaction is this?​

Answer 1

Answer:

=MgSO4+H2

In the above given reaction magnesium is added to sulphuric acid to form "magnesium sulphate and hydrogen gas".

Now the basic requirement for  and equation to be balanced is that the number of molecules of metal or nonmetal or gas that is present on the left side of the equation is equal to the No. of molecules of the "same on the right side".

The four elements present in the reaction that is magnesium hydrogen Sulphur and oxygen have equal number of molecules on the left and right side hence the equation that we are given is already balanced.

Explanation:

it is already balanced equation
