States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

Assume that these are typical of values that might be obtained in any other year, and discuss the trends as you move down the columns and along the rows, in terms of your knowledge of stratospheric ozone behavior.
In the stratosphere, 85-90 % of total ozone present for the specific location above the surface. The measuring unit Dobson unit (DU) is used to calculated the thickness of ozone in the atmosphere. From the given data, Kiev has the relatively higher amount of ozone which is due to the fact that amount of ozone is higher almost all seasons at the middle and higher latitude.
In the tropical region, such as Kenya, the lower amount of ozone and approximately same in all seasons, this can be explain using the Brewer-Dobson circulation model and according to this model, due to the slow atmospheric circulation, in which the ozone moves from tropic region to middle and polar latitudes.
