Question

A polysaccharide is a polymer made from simple sugars. A saturated hydrocarbon has no double bonds. The membrane of an animal cell is composed primarily of phospholipids. A triple bond between two carbons consists of 2 sigma-bonds and 1 pi-bond. In nuclear fission, light elements combine to form heavier ones. The color of a compound depends on the wavelengths of light that it absorbs. A catalyst changes the equilibrium constant of a reaction. A buffer solution is composed of a strong acid and its conjugate base. The oxidation number of an atom cannot change during a reaction. In water, ammonia acts as a weak base. In a reversible process, the change in free energy is negative. In a voltaic cell, oxidation occurs at the cathode. A bidentate ligand has two donor atoms. A diamagnetic material contains no unpaired electrons. DNA is an abbreviation for deoxyribonucleic acid.
