MnO₂(s) + 4 HCl(aq)→ MnCl₂(aq) + 2 H₂O(l) + Cl₂(g)
Step-by-step explanation:
When aqueous solution of hydrochloric acid (HCl) reacts with solid Manganese(IV)oxide to form manganese(II)chloride in aqueous form, liquid water and then chlorine gas. The equation is given as,
MnO₂(s) + HCl(aq)→ MnCl₂(aq) + H₂O(l) + Cl₂(g)
It can be balanced by writing 2 in front of water and then writing 4 in front of HCl as,
MnO₂(s) + 4 HCl(aq)→ MnCl₂(aq) + 2 H₂O(l) + Cl₂(g)
So the balanced equation was found.
