oxidation
A quadratic equation.
Yes. 3a plus 12 plus 6 is an example of an Equation.
The reaction shown in the thermochemical equation is an exothermic reaction. This is because heat is a reactant (on the left side of the equation) and is released during the reaction.
Displacement reaction
An unbalanced reaction equation.
There is no equation because there is no reaction.
This is the chemical reaction for burning of propane.
The equation for magnesium plus fluorine is: Mg + F2 → MgF2. This reaction results in the formation of magnesium fluoride.
The balanced chemical equation for the reaction is: ZnS + 2HCl → ZnCl2 + H2S
This reaction is called "metal-metal exchange reaction".

Na + 2S --> Na2S Sodium and Sulphur yield Sodium Sulphide.
This is an acid-base reaction or proton exchange, but there are many more reaction possibillities depending of Cu2+, OH- and NH3 concentration
