Temperature: 800 - 1000°C
Explanation: The ideal environmental conditions for a reaction, such as temperature, pressure, catalysts, and solvent. Catalysts are substances that speed up the pace (velocity) of a chemical reaction without being consumed or becoming part of the end product. Catalysts have no effect on equilibrium situations.

Zn is oxidized by oxygen
This equation does not have any specific information about phenomenon.
In this case, you just need to observe to see if product substance ZnO (zinc oxide), appearing at the end of the reaction.
Or if any of the following reactant substances Zn (zinc), disappearing
