Reactivity	Reacts with acids to produce hydrogen gas. Forms oxides when heated in air.
Corrosion Resistance	Zinc exhibits excellent corrosion resistance and is commonly used as a protective coating.
Alloy Formation	Forms alloys with other metals such as copper (brass) and aluminum (zinc-aluminum alloy).
Reducing Agent	Can act as a reducing agent in certain chemical reactions, such as with copper oxide.
Formation of Compounds	Forms various compounds such as zinc chloride (ZnCl2), zinc sulfate (ZnSO4), and zinc oxide (ZnO).
Amphoteric Nature	Exhibits an amphoteric nature, meaning it can react with both acids and bases.

Now before let's check out the reaction:

zinc (zn) Chemical Reactions

Reaction Description	Chemical Equation	Interpretation
Zinc and Hydrochloric Acid (HCl)	$\text{Zn}+2\text{HCl}\to {\text{ZnCl}}_2+{\text{H}}_2$	Zinc reacts with hydrochloric acid to produce zinc chloride and hydrogen gas.
Zinc and Sulfuric Acid (H2SO4)	$\text{Zn}+{\text{H}}_2{\text{SO}}_4\to {\text{ZnSO}}_4+{\text{H}}_2$	Zinc reacts with sulfuric acid to form zinc sulfate and hydrogen gas.
Zinc Oxide (ZnO) and Hydrogen Gas (H2)	$\text{ZnO}+{\text{H}}_2\to \text{Zn}+{\text{H}}_2\text{O}$	Zinc oxide reacts with hydrogen gas to produce zinc and water vapor.
Zinc and Copper(II) Sulfate (CuSO4) Solution	$\text{Zn}+{\text{CuSO}}_4\to {\text{ZnSO}}_4+\text{Cu}$	Zinc displaces copper from copper sulfate solution to form zinc sulfate and copper metal.
Zinc and Nitric Acid (HNO3)	$3\text{Zn}+8{\text{HNO}}_3\to 3\text{Zn}({\text{NO}}_3{)}_2+2\text{NO}+4{\text{H}}_2\text{O}$	Zinc reacts with nitric acid to produce zinc nitrate, nitrogen dioxide gas, and water.
Zinc and Oxygen (Combustion Reaction)	$2\text{Zn}+{\text{O}}_2\to 2\text{ZnO}$	Zinc reacts with oxygen in the air during combustion to form zinc oxide.
