Carry out the transformations CaCO3-CaO-CaC2 – C2H2-C2H4-C2H4Br2
| January 13, 2021 | education
1) CaCO3 = CaO + CO2 (when heated, calcium carbonate decomposes into calcium oxide and carbon dioxide);
2) CaO + 3C = CaC2 + CO (when calcium oxide interacts with carbon, calcium carbide and carbon monoxide are formed);
3) CaC2 + H2 = Ca + C2H2 (when calcium carbide interacts with hydrogen, calcium and acetylene are formed);
4) C2H2 + H2 = C2H4 (when acetylene interacts with hydrogen, ethylene is formed);
5) C2H4 + Br2 = C2H4Br2 (when ethylene reacts with bromine, 1,2-dibromoethane is 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.
