Equations of reactions of interaction with water of the following substances: K2O, BaO, P2O5, SO2, Ca, K

Basic oxides – K2O, BaO interact with water.
Let’s write down the reactions of the connection:
1. K2O + 2H2O = 2KOH;
2. BaO + H2O = Ba (OH) 2;
Oxides – P2O5, SO2 interact with water to form acids:
3. P2O5 + 3H2O = 2H3PO4;
4. SO2 + H2O = H2SO3;
Metals – calcium, potassium are strong reducing agents; they react with water under normal conditions. These reactions are redox:
5. Ca + 2H2O = Ca (OH) 2 + H2 – ОВР;
6.2K + 2H2O = 2KOH + H2 – ORP

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
