Question

CoO(S)+H2O....... Ca(OH).
Here calcium oxide and water react to form................................

Answer 1

Firstly you have typed a wrong symbol because CoO means

cobalt oxide

So calcium oxide reacts with water to form calcium hydroxide

CaO + H2O= Ca(OH)2

Answer 2

.CaO + H2O → Ca(OH)22.CaO + CO + H2O → H2 + CaCO33.CaO + H2O → Ca(OH)2H2O4.CaO + H2O → OH + Ca5.CaSO4 + CaO + H2O → CaSO4*2H2O + Ca(OH)26.CaO + H2O → (OH)2 + Ca7.CaO + H2O → CaO2H28.Na2HPO4 + CaO + H2O → Na2CaO2 + H3PO49.CaO + H2O → CaOH + O2
