This is the MINIMUM energy required for a reaction to work or to be activated. If this energy is not reached, the reaction in full does not happy. Imagine a game of basketball. If you do not shoot the ball h...

Chlorine, Cl, and Florine, F are both in group 7 of the periodic table so they have 7 electrons in the outer energy level, called valence electrons. Each fluorine atom makes one covalent bond to the chlorine...

A pair of strutural isomers are two molecules which have the same molecular formula; the same number of each atom, but which have these atoms arranged differently, and are therefore distinct molecules. An ex...

The Le Chatelier principle was estates that if there is a change in the conditions in a dynamic equilibrium system, the equilibrium of the system will move in order to counteract the change. The conditions t...

The reducing ability of halide ions increases as we go down the group because the size of the ions increases down the group meaning the outer shell electron that gets lost when the ion is oxidised is further...
