Question

Ca – CaO + H2O =?Ba-BaO+H2O=Ca-CaO+H2O=​

Answer 1

Ответ:

2Ca + O2 → 2CaO

CaO + H2O → Ca(OH)2

2Ba + O2 → 2BaO

BaO + H2O → Ba(OH)2

Объяснение:

Answer 2

The given chemical equations involve the reactions of calcium (Ca), barium (Ba), and their respective oxides with water (H2O). Let's balance these equations:

1. For the reaction of calcium (Ca) and calcium oxide (CaO) with water: Ca + CaO + 2H2O → 2Ca(OH)2

2. For the reaction of barium (Ba) and barium oxide (BaO) with water: Ba + BaO + 2H2O → 2Ba(OH)2

In both reactions, the metal reacts with water to form their respective hydroxides. The equations are balanced, and the products are calcium hydroxide (Ca(OH)2) and barium hydroxide (Ba(OH)2).
