sulphur dioxide reacts with oxygen to produce sulphur trioxide, balance the chemical equation using lcm method?​

2SO2 + O2 → 2SO3

Explanation:

According to this question, sulphur dioxide (SO2) reacts with oxygen to produce sulphur trioxide (SO3). The equation is as follows:

SO2 + O2 → SO3

The above equation is unbalanced because there are unequal number of atoms of each element in the both reactants and products. To balance the equation, we use coefficients to make the number of atoms equal. The balanced equation is as follows:

2SO2 + O2 → 2SO3

- There are 2 moles of S on both sides of the equation.

- There are 4 moles of Oxygen on both sides of the equation.
