What Are The Physical And Chemical Properties Of ZnH2?

ZnH2, or zinc hydride, is a binary compound consisting of zinc and hydrogen. It is a white crystalline solid that is insoluble in water but can react with acids to release hydrogen gas.

Physically, ZnH2 has a melting point of approximately 200°C and a boiling point of around 350°C. It is relatively stable and can be stored under normal conditions without significant decomposition.

Chemically, ZnH2 is a reducing agent and can react with various oxidizing agents such as halogens, oxygen, and acids. When heated, it can decompose into its constituent elements, zinc and hydrogen. ZnH2 can also react with water to generate zinc hydroxide and hydrogen gas.

Overall, ZnH2 exhibits typical properties of a binary metal hydride and can find applications in various chemical reactions and hydrogen storage technologies.
