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.

Dinitrogen monoxide (N₂O; nitrous oxide) is a greenhousegas that enters the atmosphere principally from natural fertilize rbreakdown. Some studies have shown that the isotope ratios of ¹⁵N to ¹⁴N and of ¹⁸O to ¹⁶O in N₂O depend on the source, which can thus be determined by measuring the relative abundance ofmolecular masses in a sample of N₂O.(a) What different molecular masses are possible for N₂O?(b) The percent abundance of ¹⁴N is 99.6%, and that of ¹⁶O is 99.8%. Which molecular mass of N₂O is least common, andwhich is most common?
