2Na + O2 → Na2O2 (when sodium interacts with oxygen, sodium peroxide is formed – Na2O2)
Ca + 2HCl → CaCl2 + H2 ↑
2Zn + O2 → 2ZnO
Ca + 2H2O → Ca (OH) 2 + H2 ↑
MgO + H2O → Mg (OH) 2 (magnesium oxide interacts with water in a vapor state, the reaction occurs when heated)
Al2O3 + 3H2O → 2Al (OH) 3 (reaction is possible only at high temperature)
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.
