Gas chromatography is an analytical technique that is used to separate and analyze samples that can be vaporized without decomposing. The chromatography column contains a substance that helps separate the sample being analyzed. The sample is vaporized and carried through the column by an inert gas. As the mixture moves through the column, the compounds are separated based on how much they interact with the substance in the column. The molecules of each compound are detected as they exit the column, and a peak for each compound is produced on a chromatogram. The area under each peak on the chromatogram is proportional to the concentration of the compound in the sample. A chromatogram produced by separating a mixture of compounds is shown. Time to Go Through Column Based on the information given, which of the following statements about the chromatogram is most likely true? The three peaks each represent a different element. The three peaks each represent a different substance used to separate the compounds in the sample. The compound represented by peak A interacted the most with the substance in the column. D The sample contained more of the compound represented by peak B than of that represented by peak C. O O O (- Detector Response

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.
