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.
Why can’t traditional ClOx catalytic chemistry explain the Antarctic ozone hole? What reaction cycle does explain it?
Introduction:
The ozone layer is present in the stratosphere (upper air layer of the earth) and protects the earth from solar UV radiation. Nowadays different kinds of human activities are generating pollutants. Among those chlorinated pollutants (ClOx, chlorofluorocarbon(CFCs), etc.) are mainly responsible for degrading the ozone layer. Thinning of the ozone layer is called 'Ozone hole'.
