CaO → Ca (OH) 2 → CaCl2 → AgCl
1) CaO + H2O → Ca (OH) 2 ↓ (compound reaction; calcium oxide, water, calcium hydroxide);
2) Ca (OH) 2 ↓ + 2KCl → CaCl2 + 2KOH (exchange reaction; calcium hydroxide, potassium chloride, calcium chloride, potassium hydroxide);
3) 3CaCl2 + 2Ag (NO) 3 ↓ → 2AgCl ↓ + 3Ca (NO3) 2 (exchange reaction; calcium chloride, silver nitrate, silver chloride, calcium nitrate).
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
