Question

Осуществите следующие превращения кальций стрелка кальций O стрелка хлорид кальция стрелка аргентум хлор

Answer 1

Ca  → CaO → CaCl2 → AgCl

2Ca + O2 → 2CaO

CaO + 2HCl → CaCl2 +H2O

CaCl2 + 2AgNO3 → 2AgCl ↓ + Ca(NO3 )2

Answer 2

Transformation of Calcium to Calcium Chloride and Silver Chloride

To transform calcium into calcium chloride and silver chloride, we can use the following chemical reactions:

1. Calcium to Calcium Chloride: - The transformation of calcium to calcium chloride involves the reaction of calcium with hydrochloric acid. - The balanced chemical equation for this reaction is: ``` Ca + 2HCl → CaCl2 + H2 ``` - This reaction results in the formation of calcium chloride and hydrogen gas.

2. Calcium Chloride to Silver Chloride: - The transformation of calcium chloride to silver chloride can be achieved through a double displacement reaction with silver nitrate. - The balanced chemical equation for this reaction is: ``` CaCl2 + 2AgNO3 → 2AgCl + Ca(NO3)2 ``` - This reaction results in the formation of silver chloride and calcium nitrate.

These chemical reactions demonstrate the transformation of calcium into calcium chloride and subsequently into silver chloride.
