| Make up the equations for the reactions of obtaining oxides by oxidation of simple and complex substances and by decomposition of bases P; ZnS; Fe (OH) 3.
Oxides can be obtained by the interaction of simple or complex substances with oxygen. These reactions are called oxidation reactions.
P is a simple substance phosphorus, when it is oxidized, two types of oxides can be obtained, depending on the amount of oxygen that reacts:
a) 4 P + 5 O2 = 2 P2O5;
b) 2 Р + 3 О2 = 2 Р2О3.
ZnS is zinc sulfide. When it is oxidized, 2 oxides are formed:
2 ZnS + 2 О2 = 2 ZnО + SO2.
Oxides are also formed during the decomposition of insoluble bases:
2 Fe (OH) 3 = Fe2O3 + 3 H2O.
