(a)
Interpretation:
Whether the given reaction, 2KClO3(s) Δ→ 2KCl(s) + 3O2(g) is a decomposition (D), combination (C), single-replacement (SR) or double-replacement (DR) reaction has to classified.
Concept Introduction:
Combination reaction (C) is a reaction in which two or more elements or compounds join together producing a product of different composition. The general form of a combination reaction is A + B → AB.
Decomposition reaction (D) is a reaction in which a single reactant undergoes decomposition and gives two or more products. The general form of a decomposition reaction is AB → A + B.
Single-replacement reaction (SR) is a reaction in which one atom replaces another in the compound and produces a new compound. The general form of a single-replacement reaction is A + BC → AC + B.
Double-replacement reaction (DR) is a reaction in which two compounds undergoes “change of partners”. That is, two compounds react by exchanging atoms to produce two new compounds. The general form of a double-replacement reaction is AB + CD → AD + CB.
(b)
Interpretation:
Whether the given reaction, K2CO3(aq) + Ca(OH)2(aq) → CaCO3(s) + 3KOH(aq) is a decomposition (D), combination (C), single-replacement (SR) or double-replacement (DR) reaction has to classified.
