Basics of solution formation learning goal: to learn how the solvent water forms hydrogen bonds, solvates polar molecules, and weakens ionic bonds. water is one of the most essential substances on earth. one of the most important properties of water is its ability to dissolve many different substances. the bent nature of the molecule and the unequal charge distribution play pivotal roles in the solution process. polarity: polarity is directly proportional to the dipole moment of a chemical bond. ionic nature: the ionic nature of a compound depends on the difference in electronegativity between atoms. hydrogen bonding: hydrogen bonding is a weak electrostatic attractive force developed between partly polar hydrogen and a highly electronegative atom, usually oxygen, nitrogen, or fluorine. part a check all that apply. water is known as a polar molecule because

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
