Consider the reaction: KBr (aq) + AgNO3 (aq) → KNO3 (aq) + AgBr (s) This is an example of: (a) Decomposition reaction (b) Combination reaction (c) Double displacement reaction Displacement reaction

Option (c) is the answer. Double displacement reaction is the given reaction that is exchange of ions takes place between both the reactants.

• You are given the following chemical equation: Mg(s) + CuO(s) →MgO(s) + Cu (s)
