Complete the blanks in the sentences given below with appropriate expressions. ………………………. Is a separation and purification technique consisting of a solid phase and a liquid or a gas. …………………………, stationary phase is a liquid that does not evaporate easily, attached as a thin layer on the surface of an inert solid. A liquid or a gas is used as the mobile phase to separate the mixture. …………………………., As stationary phase. a resin is used. The structure of the resin can consist of anionic or cationic ions. ………………, The stationary phase is a gel permeable. The gel has a porous structure.
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.
