Write the molecular reaction equation corresponding to the abbreviated ionic: CaCO3 + 2H (+) = Ca (2+) + H2O + CO2

Calcium carbonate reacts with sulfuric acid to form calcium sulfate and carbonic acid. Carbonic acid is fragile, decomposes into carbon dioxide and water.

CaCO+ H2SO4 = CaSO+ H2O + CO2↑.

CaCO+ 2H1+ +SO41- = Ca2+ + SO42- + H2O + CO2↑.

CaCO+ 2H1+  = Ca2+  + H2O + CO2↑.



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.
