When we balance this equation

SnO₂(s) + H₂(g) ⇄ Sn(s) + H₂O(g)

We will get

SnO₂(s) + 2H₂(g) ⇄ Sn(s) + 2H₂O(g)

Solution:

Balancing this equation

SnO₂(s) + H₂(g) ⇄ Sn(s) + H₂O(g)

We have to balance the number of O

SnO₂(s) + H₂(g) ⇄ Sn(s) + 2H₂O(g)

We have to balance the number of H

SnO₂(s) + 2H₂(g) ⇄ Sn(s) + 2H₂O(g)

We will get the balanced equation

SnO₂(s) + 2H₂(g) ⇄ Sn(s) + 2H₂O(g)

The reaction quotient will be

Qc = [product] / [reactant]

Qc = [Sn(s) + H₂O(g)] / [SnO₂(s) + H₂(g)]
