To determine the types of chemical reactions, we need to analyze the reaction equations and identify the changes in bonding and composition. Here's how we can figure it out:
1. Al + GaP → Ga + AlP:
This equation represents a single replacement reaction (d). Here, aluminum (Al) replaces gallium (Ga) in gallium phosphide (GaP) to form aluminum phosphide (AlP) and gallium.
2. 2 Mg + O2 → 2 MgO:
This equation represents a synthesis reaction (a). Synthesis reactions combine two or more substances to form a new compound. In this case, magnesium (Mg) reacts with oxygen (O2) to form magnesium oxide (MgO).
3. MgO + BeSe → BeO + MgSe:
This equation represents a double replacement reaction (c). Double replacement reactions occur between two compounds, where the positive ions (cations) and negative ions (anions) of the compounds switch places. In this case, magnesium oxide (MgO) reacts with beryllium selenide (BeSe) to form beryllium oxide (BeO) and magnesium selenide (MgSe).
4. CH4 + 2O2 → CO2 + 2H2O:
This equation represents a combustion reaction (e). Combustion reactions involve the reaction of a fuel (usually a hydrocarbon) with oxygen to produce carbon dioxide (CO2) and water (H2O). In this case, methane (CH4) reacts with oxygen (O2) to form carbon dioxide (CO2) and water (H2O).
5. 2 NaCl → Na + Cl2:
This equation represents a decomposition reaction (b). Decomposition reactions involve the breakdown of a compound into simpler substances. In this case, sodium chloride (NaCl) breaks down into sodium (Na) and chlorine (Cl2).
By analyzing the changes in substances and bonds, we can classify each reaction accurately.
