Question

K+H2O→? BaO+H2O→? CO2+H2O→? P2O3+H20→?

Answer 1

2K+2H2O→2KOH+H2BaO+H2O→Ba(OH)2
CO2+H2O→H2CO3
P2O3+H20→H2PO4

Answer 2

Balanced Chemical Equations:

1. K + H2O → KOH + H2 - The balanced equation for the reaction between potassium (K) and water (H2O) is K + H2O → KOH + H2 [[6]](https://cchgeu.ru/upload/iblock/c99/rab_progr_khimiya_2019.pdf).

2. BaO + H2O → Ba(OH)2 - The balanced equation for the reaction between barium oxide (BaO) and water (H2O) is BaO + H2O → Ba(OH)2 [[4]](https://uchi.ru/otvety/questions/reshite-tsepochku-prevrascheniy-ca-ca-oh-2-caco3-cao-cacl2-ca-t-bao-ba-oh-2-ba-no3-2-nano).

3. CO2 + H2O → H2CO3 - The balanced equation for the reaction between carbon dioxide (CO2) and water (H2O) is CO2 + H2O → H2CO3 [[5]](https://elar.urfu.ru/bitstream/10995/34779/1/978-5-321-02439-3.pdf).

4. P2O3 + H2O → H3PO3 - The balanced equation for the reaction between phosphorus trioxide (P2O3) and water (H2O) is P2O3 + H2O → H3PO3.

Please note that these equations represent the balanced chemical reactions between the given reactants and products.
