Arrange the coefficients in the equations of chemical reactions, determine their types

Arrange the coefficients in the equations of chemical reactions, determine their types: a) Pb (NO3) 2 → PbO + NO2 + O2 b) KNO3 → KNO2 + O2 c) Li + N2 → Li3N d) B + O2 → B2O3 2. Make a chemical equation reaction, indicate its type: Phosphorus + chlorine → phosphorus (V) chloride

Let’s compose the reaction equations:
4Pb (NO3) 2 = 4PbO + 8NO2 + 2O2 – ORP;
N5 + + e = N4 + | 4 – oxidizing agent;
2O – 4e = 2O = O2 | 1 – reducing agent;
b) 2KNO3 = 2KNO2 + O2 – OBP;
N5 ++ 2e = N3 + | 2 – oxidizing agent;
2O2- – 4e = 2O | 1- reducing agent;
c) 6Li + N2 = 2Li3N – OBP;
Li – e = Li + | 6 – reducing agent;
2N + 6e = 2N3 + | 1 – oxidizing agent;
d) 4B + 3O2 = 2B2O3 – OBP;
B – 3e = B3 + | 4 – reducing agent;
2O + 4e = 2O2- | 3 – oxidizing agent;
2. 2P + 5Cl2 = 2PCL5 – OBP;
P – 5e = P5 + | 2 – reducing agent;
2Сl + 2e = 2Cl- | 5 – oxidizing agent.
