1) C + O2 = CO2 (when carbon interacts with oxygen, carbon dioxide is formed);
2) CO2 + Ca (OH) 2 = CaCO3 + H2O (when carbon dioxide interacts with calcium hydroxide, calcium carbonate and water are formed);
3) CaCO3 + 2HCl = CaCl2 + CO2 + H2O (when calcium carbonate interacts with hydrochloric acid, calcium chloride, carbon dioxide and water are formed);
4) CaCl2 + 2AgNO3 = Ca (NO3) 2 + 2AgCl (when calcium chloride interacts with silver nitrate, calcium nitrate and silver chloride are formed).
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.
