$Mg + H_{2} {SO}_{4 \to}$

Open in App

Solution

Step 1: When Magnesium (Mg) reacts with Sulphuric acid $(H_{2} {SO}_{4})$ then it forms Magnesium sulphate $({MgSO}_{4})$ and Hydrogen gas $(H_{2})$ .
Step 2: $Mg + H_{2} {SO}_{4} \to {MgSO}_{4} + H_{2}$
Balancing by step method
1. Count the number of atoms in both the reactant and product sides.
Reactant Product
Mg - 1 Mg - 1
H - 2 H - 2
S - 1 S - 1
O - 4 O - 4
Here, Magnesium, Hydrogen, Sulphur, and Oxygen are balanced on both the sides.
Equation is balanced
Step 3: $Mg + H_{2} {SO}_{4} \to {MgSO}_{4} + H_{2}$
