77. Solving a chemistry problem
44. Make molecular and electronic equations of thermal decomposition reactions proceeding according to the schemes:
NH4H2PO4 → NH3 N2 P2O3 H2O
NaNO3 → Na2O NO2 O2
K2SO3 → K2SO4 K2S
Specify what type of redox reactions they belong to. Determine which substance or atom is an oxidizing agent and which substance or atom is a reducing agent.
