| Draw up formulas of compounds with oxygen, for sodium, lithium, calcium, barium, zinc (2), aluminum, boron (3), nitrogen (5), carbon (4), chlorine (7).
1) 2Na + O2 = 2NaO (sodium oxide)
2) 4Li + 2O2 = 2Li2O (lithium oxide)
3) 2Ca + O2 = 2CaO (calcium oxide)
4) 2Ba + O2 = 2BaO (barium oxide)
5) 2Zn + O2 = 2ZnO (zinc oxide (2))
6) 2Al + 3O2 = 2Al2O3 (aluminum oxide)
7) 2B + 3O2 = 2B2O3 (boron oxide (3))
8) 2N2 + 5O2 = 2N2O5 (nitric oxide (5))
9) С + O2 = CO2 (carbon monoxide (4))
10) 2Cl2 + 7O2 = 2Cl2O7 (chlorine oxide (7))
