Question

Са --->Са(ОН)2--->СaCO3--->CaO--->Са(ОН)2--->СaCl2 Всем привет) Кто-нибудь умеет решать эту хрень? Помогите пожалуйста...

Answer 1

1. Ca+2H20=Ca(OH)2 + H2 ; 2. Ca(OH)2 +Na2CO3= CaCO3+2NaOH ; CaCO3= CO2 + CaO ; CaO + H-OH = Ca(OH)2 ; Ca(OH)2 + CuCl2 = CaCl2 + Cu(OH)2 

это называется цепочка превращений:))

Answer 2

Reaction Steps

The chemical reaction you described can be broken down into the following steps:

Ca(OH)2 → CaCO3 + H2O Calcium hydroxide (slaked lime) reacts with carbon dioxide in the air to form calcium carbonate (limestone) and water. This reaction is commonly seen in the formation of stalactites and stalagmites in caves.

CaCO3 → CaO + CO2 Calcium carbonate decomposes when heated to form calcium oxide (quicklime) and carbon dioxide. This reaction occurs at temperatures above 825°C.

CaO + H2O → Ca(OH)2 Calcium oxide reacts vigorously with water to form calcium hydroxide and release heat. This reaction is called slaking of lime and is used to prepare slaked lime.

Ca(OH)2 + 2HCl → CaCl2 + 2H2O Calcium hydroxide reacts with hydrochloric acid to form calcium chloride and water.

Let me know if you need help understanding or working through any part of this chemical reaction sequence. I'm happy to explain further.
