Na2O
combustion
4K + O2 = 2K2O so the "coefficient" is 1
A balanced equation has equal numbers of each type of atom on each side of the equation..The chemical equation describes the balanced reaction between lead and oxygen to form lead oxide is as follows .4Pb + 3O2 → 2Pb2O3.
A Combustion reaction. It usually happens between a gas and oxygen. The products are CO2 and H2O.
One possibility is: 2 SO2 + O2 = 2 SO3
Oxidation
combustion
Hydrogen + oxygen → water2H2 + O2 → 2H2O
S+O2 = SO2
CaCl2 + 2H2O so it makes Calcium chloride and water. ==
2CO + O2 = 2CO2
2h2 + o2 2h2o
4K + O2 = 2K2O so the "coefficient" is 1

Sodium particularly reacts with the Oxygen in the Air while burning. Sodium + Oxygen ----> Sodium oxide
