Please solve question num 18 Hydrogen BondsHydrogen bonds are an interesting consequence of polar covalent bonding between two molecules, one ofwhich involves hydrogen as a partially positive atom. Unlike all other atoms that have filled shells ofelectrons that remain attached irrespective of the chemical bonding type (maintaining the atom size in theprocess), hydrogen has no filled low-energy shells, and feels all its electrons pull away in polar covalentbonds. This shrinks the size of electropositive hydrogen atoms considerably, and greatly concentrates thepartial positive change. This causes the hydrogen atom to form a surprisingly strong charge attraction tolone pair of electrons on a partially negatively-changed atom in another molecule. This semi-ionic bondbetween two polar covalent molecules mediated by an electropositive hydrogen atom is called a hydrogenbond, and it is a major determinant in protein interactions in biological systems.Shown below is a hydrogen bond (dotted line) between acetic acid (the acid of vinegar) and water.

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.
