उत्तर

Zinc Oxide is an inorganic compound with formula ZnO. It is insoluble in water. When Zinc oxide reacts with hydrochloric acid it forms zinc chloride and water. It also leads to the formation of small bubbles of hydrogen. This is a double displacement reaction.

Chemical Equation: 

\[\ce{ZnO + 2HCl -> ZnCl2 + H2O}\]
