Write the reaction equation: Li → Li2O → LiOH → Li3PO4

Lithium is an alkali metal, but relatively stable in air.

In oxygen, when heated, it burns, turning into oxide Li2O:
1) 4 Li + O2 → 2 Li2O
Lithium oxide react with water:
2) Li2O + H2O → 2 LiOH
Lithium orthophosphate is obtained by exchange reactions, using its poor solubility:
3) 3 LiOH + H3PO4 → Li3PO4 + 3 H2O

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.
