Question

How does oxygen react with metals and non-metals?

Answer 1

Combustion:

• Combustion refers to the process where a substance burns in the presence of Oxygen, giving off heat and light in the process.
• Reaction of Oxygen (${\mathrm{O}}_2$) with metals and non-metals results in the formation of its oxide.
• When a metal oxide will be basic in nature and non-metal oxide are acidic in nature.

For example:

• The reaction of Metal with Oxygen :
  $\underset{\mathrm{Magnesium}}{\mathrm{Mg}\left(\mathrm{s}\right)}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Magnesium}\mathrm{oxide}}{\mathrm{MgO}\left(\mathrm{s}\right)}$
• The reaction of nonmetals with Oxygen :
  $\underset{\mathrm{Sulfur}}{\mathrm{S}\left(\mathrm{s}\right)}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Sulphur}\mathrm{dioxide}}{{\mathrm{SO}}_2\left(\mathrm{g}\right)}$
