Conduction
In conduction, heat transfer takes place between objects by direct contact.
Convection
In convection, the heat transfer takes within the fluid.
Radiation
In radiation, heat transfer occurs through electromagnetic waves without involving particles.

Answer:
Let us write down the reaction equations for inorganic substances:
N2 + 3H2 = 2NH3 – redox reaction (ORR), ammonia was obtained;
4NH3 + 5O2 = 4NO + 6H2O – ОВР, nitrogen oxide was formed (2);
2NO + O2 = 2NO2 – ОВР, nitrogen oxide was released (4);
H2O + 2NO2 = HNO3 + HNO2 – OBP, nitric acid obtained;
2HNO3 + PbO = Pb (NO3) 2 + H2O – ion exchange, lead nitrate was formed;
2Pb (NO3) 2 = 2PbO + 4NO2 + O2 – OBP, oxygen was obtained.
The reaction products are of practical importance, for example, lead nitrate is the basis for obtaining pigments necessary for dyeing fabrics in the textile industry. These reactions show the connection of non-metals, hydrides, oxides, acids, salts.
Answer:
After the full moon (maximum illumination), the light continually decreases. So the waning gibbous phase occurs next. Following the third quarter is the waning crescent, which wanes until the light is completely gone -- a new moon.
