Question

3) Вода вступает в реакции соединения с веществами: а) Ca(OH)2 и Fe; в) N2 и SO3; б) CaO и CuSO4; г) Са и CO. Напишите уравнения возможных реакций.

Answer 1

Б) CaO +H2O => Ca(OH)2 (в осадок)
СuSO4 + H2O = (CuOH)2SO4+ H2SO4

Answer 2

CaO + H2O = Ca(OH)2

CO + H2O = CO2 + H2

Answer 3

Chemical Reactions of Water with Compounds

a) Ca(OH)2 and Fe: The possible reaction between Ca(OH)2 and Fe can be represented by the following equation: ``` Ca(OH)2 + Fe → Ca + Fe(OH)2 ``` This reaction results in the formation of calcium and iron(II) hydroxide.

b) N2 and SO3: The reaction between N2 and SO3 can be represented as: ``` N2 + SO3 + H2O → 2HNO3 ``` This reaction leads to the formation of nitric acid.

c) CaO and CuSO4: The potential reaction between CaO and CuSO4 is given by: ``` CaO + CuSO4 → CaSO4 + CuO ``` This reaction yields calcium sulfate and copper(II) oxide.

d) Ca and CO: The reaction between Ca and CO can be represented as: ``` Ca + CO2 + C → CaCO3 ``` This reaction results in the formation of calcium carbonate.

These equations illustrate the possible reactions of water with the specified compounds.
