Question

what type of reaction is shown below? 2kclo₃(s)→2kcl(s)+3o₂(g) synthesis combustion decomposition single replacement

Explanation:

• Synthesis reaction: A synthesis reaction is when two or more reactants combine to form a single product. For example, \(A + B

ightarrow AB\). In the given reaction \(2KClO_{3}(s)
ightarrow 2KCl(s)+3O_{2}(g)\), there is one reactant and two products, so it is not a synthesis reaction.

• Combustion reaction: A combustion reaction is a reaction of a substance with oxygen (usually from the air) that releases energy in the form of heat and light. The general form is \(Fuel + O_{2}

ightarrow products\). The given reaction does not involve reacting with oxygen from the air in the sense of a combustion process (e.g., burning), so it is not a combustion reaction.

• Decomposition reaction: A decomposition reaction is a reaction in which a single compound breaks down into two or more simpler substances. The general form is \(AB

ightarrow A + B\). In the reaction \(2KClO_{3}(s)
ightarrow 2KCl(s)+3O_{2}(g)\), \(KClO_{3}\) (a single compound) breaks down into \(KCl\) and \(O_{2}\) (simpler substances), which matches the form of a decomposition reaction.

• Single - replacement reaction: A single - replacement reaction is a reaction in which one element replaces another element in a compound. The general form is \(A+BC

ightarrow AC + B\). In the given reaction, there is no element replacing another element in a compound in the way described by the single - replacement reaction formula.

Answer:

decomposition
