To classify the types of chemical reactions, you can use some common classification schemes. Below are the explanations for each reaction:
1. Al + GaP → Ga + AlP:
This is an example of a single replacement reaction (d). In this reaction, aluminum (Al) replaces gallium (Ga) in the compound GaP, resulting in the formation of Ga and AlP.
2. 2 Mg + O2 → 2 MgO:
This reaction represents a combustion reaction (e). In a combustion reaction, a substance reacts with oxygen to produce carbon dioxide and water. In this case, magnesium (Mg) reacts with oxygen (O2) to form magnesium oxide (MgO).
3. MgO + BeSe → BeO + MgSe:
This is an example of a double replacement reaction (c). Double replacement reactions occur when the cations and anions of two different compounds switch places, leading to the formation of two new compounds. In this reaction, magnesium oxide (MgO) reacts with beryllium selenide (BeSe), resulting in the formation of beryllium oxide (BeO) and magnesium selenide (MgSe).
4. CH4 + 2O2 → CO2 + 2H2O:
This reaction is a combustion reaction (e) as well. Methane (CH4) reacts with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O).
5. 2NaCl → Na + Cl2:
This is an example of a decomposition reaction (b). In a decomposition reaction, a compound breaks down into two or more simpler substances. Here, sodium chloride (NaCl) breaks down into sodium (Na) and chlorine gas (Cl2).
Al + GaP → Ga + AlP: Single Replacement (d)
2 Mg + O2 → 2 MgO: Combustion (e)
MgO + BeSe → BeO + MgSe: Double Replacement (c)
CH4 + 2O2 → CO2 + 2H2O: Combustion (e)
2 NaCl → Na + Cl2: Decomposition (b)
