What types of chemical reactions are the following?
Column A
1. AI + + GaP → Ga + AIP
2. 2 Mg + O2 → 2 MgO
3. MgO + BeSe → BeO + MgSe
4. Ch4 + 2O2 → CO2 + 2H2O
5. 2 NaCI → Na + CI2
Column B
a. Double Replacement
b. Synthesis
c. Combustion
d. Single Replacement
e. Decomposition
Column A
1. AI + + GaP → Ga + AIP - d. Single Replacement
2. 2 Mg + O2 → 2 MgO - c. Combustion
3. MgO + BeSe → BeO + MgSe - a. Double Replacement
4. CH4 + 2O2 → CO2 + 2H2O - c. Combustion
5. 2 NaCI → Na + CI2 - b. Synthesis
To determine the types of chemical reactions in Column A and Column B, we need to understand the different types of reactions.
1. Double Replacement (also called metathesis) reaction: It occurs when the positive ions or cations of two compounds switch places. The general formula is AB + CD → AD + BC.
2. Synthesis (also called combination) reaction: It occurs when two or more simple substances combine to form a more complex substance. The general formula is A + B → AB.
3. Combustion reaction: It occurs when a substance reacts with oxygen, usually releasing heat and light energy. The general formula is fuel + oxygen → carbon dioxide + water.
4. Single Replacement (also called displacement) reaction: It occurs when one element replaces another element in a compound. The general formula is A + BC → AC + B.
5. Decomposition reaction: It occurs when a compound breaks down into simpler substances. The general formula is AB → A + B.
Now, let's match each reaction in Column A with the corresponding type of reaction in Column B:
1. AI + + GaP → Ga + AIP
This is a Single Replacement reaction (d). AI replaces Ga in the compound GaP.
2. 2 Mg + O2 → 2 MgO
This is a Synthesis reaction (b). Two atoms of Mg combine with one molecule of O2 to form MgO.
3. MgO + BeSe → BeO + MgSe
This is a Double Replacement reaction (a). The positive ions of MgO and BeSe switch places to form BeO and MgSe.
4. CH4 + 2O2 → CO2 + 2H2O
This is a Combustion reaction (c). CH4 (methane) combines with oxygen to produce carbon dioxide and water.
5. 2 NaCl → Na + Cl2
This is a Decomposition reaction (e). Two molecules of NaCl break down into sodium (Na) and chlorine (Cl2).
So, the types of chemical reactions in Column A are:
1. Single Replacement
2. Synthesis
3. Double Replacement
4. Combustion
5. Decomposition
And their corresponding letters in Column B are:
a. Single Replacement
b. Synthesis
c. Double Replacement
d. Combustion
e. Decomposition
Column A
1. AI + + GaP → Ga + AIP - d. Single Replacement
2. 2 Mg + O2 → 2 MgO - c. Combustion
3. MgO + BeSe → BeO + MgSe - a. Double Replacement
4. Ch4 + 2O2 → CO2 + 2H2O - c. Combustion
5. 2 NaCI → Na + CI2 - e. Decomposition
