Problem

When calcium oxide is mixed with water, the name of the chemical reaction and product formed is- (1) (A) Decomposition reaction, Ca2OH\text{Ca}_2\text{OH} (B) Combination reaction, Ca(OH)2\text{Ca(OH)}_2 (C) Displacement reaction, Ca(OH)3\text{Ca(OH)}_3 (D) Double Displacement reaction, Ca(OH)2\text{Ca(OH)}_2
Intuitive explanation

Calcium oxide reacting with water is a synthesis reaction where a new compound forms from two simpler substances. The key insight is recognizing that this is an exothermic reaction—it releases significant heat—and produces calcium hydroxide, a strong base. Understanding this reaction helps you see how oxides can transform into hydroxides by simply adding water, a pattern that repeats across many metal oxides in chemistry.
