Question

Превращения: CaO--Ca(OH)--CaSO4

Answer 1

$CaO + H_2O \rightarrow Ca(OH)_2 \\ Ca(OH)_2 + H_2SO_4 \rightarrow CaSO_4 + 2H_2O$

Answer 2

CaO+H2O=Ca(oh)2
Ca(oh)2+Na2so4=Caso4+2naoh

Answer 3

The series of transformations you've mentioned appears to be a chemical reaction involving calcium oxide (CaO) and sulfuric acid (H2SO4). Let's break down the steps of the reaction:

1. CaO (Calcium oxide) reacts with H2O (water) to form Ca(OH)2 (Calcium hydroxide): CaO + H2O → Ca(OH)2

2. Ca(OH)2 (Calcium hydroxide) reacts with H2SO4 (sulfuric acid) to form CaSO4 (Calcium sulfate) and water (H2O): Ca(OH)2 + H2SO4 → CaSO4 + 2H2O

So, the complete transformation is: CaO + H2O → Ca(OH)2 + H2SO4 → CaSO4 + 2H2O

Keep in mind that these reactions are theoretical and might not happen under certain conditions or in certain environments. Also, the specific conditions of the reaction (temperature, concentration, etc.) can influence the outcome. If you plan to conduct any chemical experiments, always ensure to follow safety guidelines and protocols.
