Question

CaCl > Ca > Cao>Ca(OH)2 CaCO3 > Ca(HCO3)2​

Answer 1

Ответ:

Объяснение:

CaCl2 -> Ca + Cl2

2Ca + O2 = 2CaO

CaO + H2O = Ca(OH)2

Ca(OH)2 + CO2 = CaCO3 + H2O

CaCO3 + CO2 + H2O = Ca(HCO3)2

Answer 2

It seems like you're trying to represent a series of chemical compounds involving calcium (Ca) in a specific order. Let me help you understand the order you've presented:

1. CaCl: This represents calcium chloride, which is an ionic compound made up of calcium (Ca) and chloride (Cl) ions.

2. Ca: This simply represents the element calcium, which exists in its elemental form.

3. CaO: This represents calcium oxide, also known as quicklime or burnt lime, which is a chemical compound of calcium and oxygen.

4. Ca(OH)2: This represents calcium hydroxide, which is a compound consisting of calcium, oxygen, and hydrogen.

5. CaCO3: This represents calcium carbonate, which is a common compound found in nature, such as in limestone and shells.

6. Ca(HCO3)2: This represents calcium bicarbonate, which is formed when carbon dioxide dissolves in water containing calcium ions.

The order you've listed these compounds seems to be based on various chemical properties, with the compounds generally becoming more complex as you move down the list. Calcium chloride (CaCl) is a simple ionic compound, while calcium bicarbonate (Ca(HCO3)2) is more complex and often found in aqueous solutions.

If you have any specific questions about these compounds or their properties, feel free to ask!
