types of chemical reactions assessment
2kclo₃ → 2kcl + 3o₂
□ synthesis/combination
□ decomposition
□ single replacement
□ double displacement
□ combustion
□ acid - base
□ precipitation
□ oxidation - reduction (redox)

Explanation:

Step1: Analyze Reaction Type

The reaction is \(2KClO_3
ightarrow 2KCl + 3O_2\). A decomposition reaction is when a single compound breaks down into two or more simpler substances. Here, \(KClO_3\) (one compound) breaks into \(KCl\) and \(O_2\) (two substances). Also, oxidation - reduction occurs (Cl in \(KClO_3\) has +5 oxidation state, in \(KCl\) it's -1; O in \(KClO_3\) has -2, in \(O_2\) it's 0), so it's also a redox reaction. But first, identify the main type.

Step2: Match with Options

• Synthesis: Combines substances, not here.
• Decomposition: Matches (one compound to two products).
• Single/Double Replacement: Involve element replacing in a compound, not here.
• Combustion: Requires fuel + \(O_2\), not here.
• Acid - Base: Involves acid and base, not here.
• Precipitation: Involves precipitate, not here.
• Redox: Also true, but the main type here is decomposition (and it's a redox reaction too). But for the options, we check each. The reaction is decomposition (and redox). But the first main type here is decomposition, and also redox. But let's check the options. The reaction \(2KClO_3

ightarrow 2KCl + 3O_2\) is a decomposition reaction (one reactant, two products) and also an oxidation - reduction (redox) reaction.

Answer:

Decomposition, Oxidation - Reduction (Redox) (the checkboxes for Decomposition and Oxidation - Reduction (Redox) should be selected)
