Here's the classification of the given chemical reactions based on the information provided:

  1. Al + GaP → Ga + AlP

    • Type: Single displacement (or single replacement) reaction. In this reaction, aluminum displaces gallium in gallium phosphide (GaP).
  2. 2 Mg + O2 → 2 MgO

    • Type: Combustion reaction. This is a reaction of magnesium with oxygen to form magnesium oxide, which is characteristic of combustion reactions.
  3. MgO + BeSe → BeO + MgSe

    • Type: Double displacement (or double replacement) reaction. In this reaction, magnesium oxide and beryllium selenide exchange constituents to form beryllium oxide and magnesium selenide.
  4. CH4 + 2O2 → CO2 + 2H2O

    • Type: Combustion reaction. In this reaction, methane (CH4) combusts in the presence of oxygen (O2) to produce carbon dioxide (CO2) and water (H2O).
  5. 2 NaCl → Na + Cl2

    • Type: Decomposition reaction. This reaction involves the decomposition of sodium chloride into sodium (Na) and chlorine gas (Cl2).

In summary:

  1. Single displacement
  2. Combustion
  3. Double displacement
  4. Combustion
  5. Decomposition
