The question is incomplete, here is the complete question:
Classify the type of the reaction (check all that apply)
1. Combination
2. Precipitation
3. Single replacement
4. Combustion
5. Double replacement
6. Acid-base
7. Decomposition
<u>Answer:</u> The given reaction is a type of precipitation and double displacement reaction.
<u>Explanation:</u>
Combination reaction is defined as the reaction in which smaller substances combine to form a larger substance.
Precipitation reaction is defined as the reaction in which an insoluble salt is formed when two solutions are mixed containing soluble substances. The insoluble salt settles down at the bottom of the reaction mixture.
Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element from its chemical reaction.
Combustion reaction is defined as the reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide gas and water molecule.
Double displacement reaction is defined as the reaction in which exchange of ions takes place.
An acid-base reaction is known as neutralization reaction. This reaction is defined as the reaction in which an acid reacts with a base to produce a salt and water molecule.
Decomposition reaction is defined as the reaction in which a large substance breaks down into smaller substances.
For the given chemical equation:
As, ions are getting exchanges and also a solid salt is getting formed. The above reaction is a type of double displacement and precipitation reaction.
Hence, the given reaction is a type of precipitation and double displacement reaction.
