This is a series of chemical reactions involving the compounds HCL (hydrochloric acid), ZnCl2 (zinc chloride), Zn(OH)2 (zinc hydroxide), ZnO (zinc oxide), and Zn(NO3)2 (zinc nitrate). The reactions can be described as follows:

HCL + ZnCl2 -> Zn(OH)2 + 2HCl
This reaction involves the neutralization of hydrochloric acid with zinc chloride to form zinc hydroxide and hydrochloric acid.

Zn(OH)2 + heat -> ZnO + H2O
Zinc hydroxide decomposes under heat to form zinc oxide and water.

ZnO + 2HNO3 -> Zn(NO3)2 + H2O
Zinc oxide reacts with nitric acid to form zinc nitrate and water.

Overall, the reactions result in the formation of zinc nitrate from the starting compounds of hydrochloric acid, zinc chloride, zinc oxide, and nitric acid.
