Answer 2

The chemical equation you provided represents a series of reactions involving sulfur trioxide (SO3), sulfuric acid (H2SO4), and calcium sulfate (CaSO4). Here is a breakdown of the reactions:

1. SO3 + H2O → H2SO4 Sulfur trioxide reacts with water to form sulfuric acid.

2. H2SO4 + CaO → CaSO4 + H2O Sulfuric acid reacts with calcium oxide (CaO) to produce calcium sulfate and water.

Therefore, the overall reaction can be summarized as:

SO3 + H2O + CaO → CaSO4 + H2O

In this reaction, SO3 reacts with water to form H2SO4, which then reacts with CaO to produce CaSO4.

Please note that this reaction is not an emergency situation, and it is not clear why you mentioned "URGENT" in your message. If you require further clarification or have a specific question about these reactions, please let me know.
