Question

....+ SO3 = CaSO4 ?????​

Answer 1

Ответ:

Нужно подставить CaO и получиться уравнение CaO+SO3=CaSO4

Answer 2

The chemical equation you provided is not balanced. The balanced equation for the reaction between sulfur trioxide (SO3) and calcium oxide (CaO) to form calcium sulfate (CaSO4) is:

CaO + SO3 → CaSO4

In this reaction, one molecule of calcium oxide reacts with one molecule of sulfur trioxide to produce one molecule of calcium sulfate. Please note that the equation you provided seems to be missing a reactant or product.
