Question

Which is the properly balanced equation that shows the synthesis of limewater, Ca(OH)2, from calcium oxide and water?

A.
CaO + H2O → Ca(OH)2

B.
Ca(OH)2 → CaO + 2H2O

C.
CaO + 2H2O → Ca(OH)2

D.
Ca(OH)2 → CaO + H2O

Answer 1

The answer is (A) calcium oxide CaO and water H₂O react to form Ca(OH)₂

Step-by-step explanation:

Answer 2

calcium oxide CaO and water H₂O react to form Ca(OH)₂


`CaO + H_2O \to Ca(OH)_2`

The answer is A.
