Lecturer and Coach (School Edu. Dept.) Comp. The question tests the understanding of basic chemical reaction types: combination, decomposition, displacement, and double displacement. Recognizing the pattern of reactants and products is key to identifying the type of reaction.
Match the following reactions with their types and choose the correct option : Reaction Type of Reaction a. Decomposition CaO + H2O → Ca(OH)2 (i) reaction CaCO3 $\xrightarb. Displacement (ii) row{\Delta}$ CaO + reaction CO2 Pb + CuCl2 → PbCl2 + c. Combination (iii) reaction Cu d. Double dis‐ Na2SO4 + BaCl2 → (iv) placement reac‐ BaSO4 + 2NaCl tion Codes : (i) (ii) (iii) (iv) (1) a b c d (2) a c b d (3) c a b d (4) c b d a (5) Question not attempted
