Which of the listed substances will react with water: potassium, silicon oxide (IV), barium oxide, hydrogen, carbon monoxide (IV).

Potassium K reacts violently with water. In the course of the reaction, a lot of heat is released per unit of time, which leads to the ignition of potassium and the released water conduit:

2K + 2H₂O = 2KOH + H₂ ↑
Barium hydroxide BaO reacts with water to form barium hydroxide:

BaO + H2O = Ba (OH) 2

Carbon monoxide (IV) CO2 is an acidic oxide that reacts with water to form carbonic acid. This acid is an unstable compound, easily decomposes into carbon dioxide and water (the type of reaction is a reversible compound reaction):

CO2 + H2O ↔ H2CO3

Silicon oxide (IV) SiO2 is an acidic oxide that does not react with water.

Hydrogen is a part of water, but does not react with it.
