Exothermic process is any process that gives off heat – transfers thermal energy from the system to the surroundings.
Establish an arbitrary scale with the standard enthalpy of formation (DH0f ) as a reference point for all enthalpy expressions.

Balancing Oxidation-Reduction Equations
Balancing Equations by the Method of HalfReactions
• MnO4- is reduced to Mn2+ (pale pink) while the C2O42is oxidized to CO2.
• The equivalence point is given by the presence of a pale pink color.
• If more KMnO4 is added, the solution turns purple

The ionic polarization results in the transition from ionic crystals to molecular crystals, leading to the decreased melting and boiling points, and even the solubility of substances
Considering the strength of ionic bond, the melting point of Al2O3 should be higher than that of MgO, but this is not true. This phenomenon is due to that the covalent component of Al2O3 is larger, and molecular crystal is formed.
