Question

Compounds that are formed by the chemical combination of a substance with Oxygen _____________________

Answer 1

• Oxidation reaction involving the addition of Oxygen to substance and removal of Hydrogen.
• Oxides are compounds formed by the chemical combination of a substance with oxygen.
• Example: Lithium($\mathrm{Li}$) combine with Oxygen(${\mathrm{O}}_2$) to form Lithium oxide(${\mathrm{Li}}_2\mathrm{O}$).
• Chemical equation: $\underset{\mathrm{Lithium}}{4\mathrm{Li}\left(\mathrm{s}\right)}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Lithium}\mathrm{oxide}}{2{\mathrm{Li}}_2\mathrm{O}\left(\mathrm{s}\right)}$

Therefore, compounds that are formed by the chemical combination of a substance with Oxygen are called oxides.
