What affects surface tension?
What affects surface tension? Surface tension depends mainly upon the forces of attraction between the particles within the given liquid and also upon the gas, solid, or liquid in contact with it. An increase in temperature lowers the net force of attraction among molecules and hence decreases surface tension. Does grease reduce surface tension? In […]
Why is CuS black?
Why is CuS black? Copper monosulfide is a chemical compound of copper and sulfur. A black colloidal precipitate of CuS is formed when hydrogen sulfide, H2S, is bubbled through solutions of Cu(II) salts. Why the valency of copper is 1 or 2? Copper has valency ‘1’ and ‘2’ that is the number of electrons lost […]

Why do A and T have 2 hydrogen bonds?
Why do A and T have 2 hydrogen bonds? Base pairing. Base pairing between adenine and thymine can be found in DNA only. There are two hydrogen bonds holding the two nitrogenous bases together. The hydrogen bonds between adenine and thymine are important for DNA to maintain a double helix structure. Why is GC rich […]
