Ionization Energy: DOWN a Group: Ionization energy DECREASES as you go DOWN a Group because the farther the valence electrons are from the nucleus (pulling power of the protons) the less energy it costs another atom to steal them
At the same time there is increased usage of chlorofluorocarbon [CFC].
CFC are halogenated compounds which have ability to destroy the ozone layer. When ultraviolet ray strike CFC in the atmosphere, it breaks the forces holding the molecule together and yield a chlorine atom. The chlorine atom then react with the ozone layer, breaking it apart and destroying it.<span />
Solution because a solution cannot be separated by hand
Answer:
Because you have to give the simplest ratio of equation. Equation I can be simplified by dividing all the coefficients by 2 to make it into equation II.
*Every equation has to be in the simplest form of coefficients.
Ratio of Equation I :
2 : 4 : 2 : 4
Ratio of Equation II :
1 : 2 : 1 : 2
