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.
This reaction is called "metal-metal exchange reaction".
The balanced chemical equation for the reaction is: ZnS + 2HCl → ZnCl2 + H2S
The equation for magnesium plus fluorine is: Mg + F2 → MgF2. This reaction results in the formation of magnesium fluoride.
