About This Quiz

This quiz challenges learners to identify types of chemical reactions, such as single replacement, double replacement, and combination. By analyzing reaction equations, participants enhance their understanding of chemical reaction classifications and their practical implications.

2.

PbO2 + 4KI ---> 2K2O + PbI4 is what type of reaction?
- Combination
- Decomposition
- Single Replacement
- Double Replacement
- Combustion
Correct Answer

A. Double Replacement

Explanation

The given reaction is a double replacement reaction because the positive ions in the reactants (Pb and K) exchange places to form new compounds (K2O and PbI4) in the products.

AgNO3 + NaCl ---> AgCl + NaNO3 is what type of reaction?
- Combination
- Decomposition
- Single Replacement
- Double Replacement
- Combustion
Correct Answer

A. Double Replacement

Explanation

The given reaction, AgNO3 + NaCl → AgCl + NaNO3, is a double replacement reaction. In this type of reaction, the positive ions of two compounds switch places to form two new compounds. In this case, the silver ion (Ag+) from silver nitrate (AgNO3) combines with the chloride ion (Cl-) from sodium chloride (NaCl) to form silver chloride (AgCl), while the sodium ion (Na+) from sodium chloride combines with the nitrate ion (NO3-) from silver nitrate to form sodium nitrate (NaNO3).

2H2 + O2 ---> 2H2O is what type of reaction?
- Combination
- Decomposition
- Single Replacement
- Double Replacement
- Combustion
Correct Answer

A. Combination

Explanation

The given chemical equation, 2H2 + O2 --> 2H2O, represents a combination reaction. In this reaction, two molecules of hydrogen gas (H2) combine with one molecule of oxygen gas (O2) to form two molecules of water (H2O). Combination reactions involve the merging of two or more substances to form a single compound.

5.

Mg + 2HCl ---> MgCl2 + H2 is what type of reaction?
- Combination
- Decomposition
- Single Replacement
- Double Replacement
- Combustion
Correct Answer

A. Single Replacement

Explanation

The given reaction, Mg + 2HCl -> MgCl2 + H2, is a single replacement reaction. In this type of reaction, one element replaces another element in a compound. Here, magnesium (Mg) replaces hydrogen (H) in hydrochloric acid (HCl) to form magnesium chloride (MgCl2) and hydrogen gas (H2).

6.

2H2O ---> 2H2 + O2 is what type of reaction?
- Combination
- Decomposition
- Single Replacement
- Double Replacement
- Combustion
Correct Answer

A. Decomposition

Explanation

The given chemical equation represents a decomposition reaction. In this type of reaction, a compound breaks down into simpler substances. In this case, water (H2O) decomposes into hydrogen gas (H2) and oxygen gas (O2).

7.

2Na + Cl2 ---> 2NaCl is what type of reaction?
- Combination
- Decomposition
- Single Replacement
- Double Replacement
- Combustion
Correct Answer

A. Combination

Explanation

The given reaction 2Na + Cl2 -> 2NaCl is a combination reaction. In a combination reaction, two or more substances combine to form a single product. In this case, sodium (Na) reacts with chlorine (Cl2) to form sodium chloride (NaCl).

Rate this question:
8.

F2 + BaCl2 ---> BaF2 + Cl2 is what type of reaction?
- Combination
- Decomposition
- Single Replacement
- Double Replacement
- Combustion
Correct Answer

A. Single Replacement

Explanation

In the given reaction, F2 (fluorine gas) is replacing Cl2 (chlorine gas) in the compound BaCl2 (barium chloride), resulting in the formation of BaF2 (barium fluoride). This type of reaction, where one element replaces another in a compound, is known as a single replacement reaction.

9.

C6H12O6 + 6O2 ---> 6CO2 + 6H2O is what type of reaction?
- Combination
- Decomposition
- Single Replacement
- Double Replacement
- Combustion
Correct Answer

A. Combustion

Explanation

The given chemical equation represents a combustion reaction. In a combustion reaction, a substance reacts with oxygen to produce carbon dioxide and water. In this equation, glucose (C6H12O6) reacts with oxygen (O2) to form carbon dioxide (CO2) and water (H2O). The presence of oxygen and the formation of carbon dioxide and water are characteristic of a combustion reaction.

10.

CH4 + 2O2 ---> CO2 + 2H2O is what type of reaction?
- Combination
- Decomposition
- Single Replacement
- Double Replacement
- Combustion
Correct Answer

A. Combustion

Explanation

The given chemical equation represents a combustion reaction. In a combustion reaction, a fuel (in this case, CH4) reacts with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). This reaction is characterized by the release of a large amount of heat and light energy.
