Substances are given: potassium carbonate, aluminum oxide, sulfuric acid solution, carbon. Write the equations for four possible reactions between these substances.

We are given substances: potassium carbonate – K2CO3, aluminum oxide – Al2O3, sulfuric acid solution – H2SO4, carbon – C. Let’s consider how these chemicals can interact with each other.

A chemical reaction takes place between substances such as potassium carbonate and sulfuric acid. The potassium sulfate salt and carbonic acid are formed.

К2СО3 + Н2SO4 = К2SO4 + Н2О + СО2

Trivalent aluminum oxide enters into a chemical reaction with sulfuric acid. In the end, we get trivalent aluminum sulfate salt and water.

Аl2О3 + 3 Н2SO4 = Аl2 (SO4) 3 + Н2О,
Aluminum oxide and carbon react to form carbon monoxide and pure aluminum.
Al2O3 + 3 C = 2 Al + 3 CO

Aluminum oxide chemically reacts with the potassium carbonate salt to form potassium hydroaluminate and carbon dioxide.
Аl2О3 + К2СО3 = СО2 + 2 КАlО2.
