Question

CaO3 + H2O =и надо название вещества в ответе ​

Answer 1

$CaCO_{3} + H_{2}O = Ca(OH)_{2} + CO_{2}$

$CaCo_{3}$ - карбонат кальция

$H_{2}O$ - вода

$Ca(OH)_{2}$ - гидроксид кальция

$CO_{2}$ - углекислый газ

Answer 2

The chemical equation you provided is not balanced. However, based on the reactants, it seems to be a combination of calcium oxide (CaO) and water (H2O). When these substances react, they form calcium hydroxide (Ca(OH)2), which is commonly known as hydrated lime or slaked lime.

The balanced equation for the reaction is:

CaO + H2O → Ca(OH)2

And the name of the substance formed (product) is calcium hydroxide (Ca(OH)2).
