Question

Write the balanced chemical equations for the following word equations:
$\left(b\right).\text{Magnesium}+\text{Sulphuric acid}\to \text{Magnesium sulphate}+\text{hydrogen}$

Answer 1

The skeletal equation is:
$Mg+H_{2}S{O}_4\to MgS{O}_4+H_2$

Count the number of atoms of each element on either side of the reaction

• Number of atoms on reactant side:

$Mg=1,H=2,S=1,O=4$

• Number of atoms on the product side:

$Mg=1,H=2,S=1,O=4$

As there are equal number of atoms on reactant and product side
So, the balanced chemical equation for the reaction is:

$Mg+H_{2}S{O}_4\to MgS{O}_4+H_2$
