Homework Answers
1) water is a polar solvent because of its bent structure as shown in the image. Oxygen is negatively charged and Hydrogen is positively charged.
2) it is non polar as due to the tetrahedral shape the polarity is cancelled.
3) solubility of a substance increases with rise in temperature.Temperature increases the kinetic energy due to which intermolecular attractions between the solute is broken and increases solubility.
4) spectator ions are the ions which remains on both reactant and product side and remain unchanged.They are omitted jn ionic equation because they don't play any role or don't participate in the reaction.

2. Identify the strongest type of intermolecular forces in acetone, ethanol, water and hexane. (Structures listed on page 15.) Experiment 2 Intermolecular Forces There are three general types of intermolecular forces. All substances exhibit London Dispersion Forces (LDF), and they are generally the weakest of the three types. These London forces are due to the attractions between small, temporary dipoles that arise from the constant, random movement of the electrons in a substance. As molar mass increases, the size of...
