The reaction KClO3 (s) → KCl (s) + O2 (g) is an example of which of the following reaction types?

Question

(Choose that all apply)

	Acid-Base (Neutralization)
	Combination (Synthesis)
	Combustion
	Decomposition
	Double Displacement (Double Replacement, Exchange)
	Oxidation-Reduction (Redox)
	Precipitation
	Single Displacement (Single Replacement)

Answer 1

Decomposition because KClO3 is decomposing into KCl an O2

Redox because oxidation number of Cl goes from 5+ to 1- and oxidation number of O goes from 2- to zero
