Answer

Brief Explanations:

  1. Water is a polar molecule, with oxygen having a partial negative charge and hydrogen having a partial positive charge due to unequal electron - sharing.
  2. Hydrogen bonds form between the partial charges of water molecules.
  3. Cohesion is the attraction between molecules of the same substance.
  4. Cohesion causes water drops to form spheres on smooth surfaces.
  5. Adhesion is the attraction between molecules of different substances.
  6. Capillary action draws water out of plant roots and up into stems.
  7. The amount of energy needed to raise a substance's temperature is called heat capacity.
  8. Water has a high heat capacity, allowing it to absorb large amounts of heat.
  9. All living things depend on a source of water.
  10. A material composed of two or more elements or compounds is called a mixture.
  11. In a salt - water solution, table salt is the solute and water is the solvent.
  12. Mixtures of water and undissolved material are called suspensions.
  13. Blood is an example of a suspension found in the body.
  14. Water molecules can split apart to form hydrogen ions (H+) and hydroxide ions (OH -).
  15. The pH scale is used to indicate the concentration of H+ ions.
  16. Without seeing Fig 2 - 10, cannot answer which substance is most acidic or neutral.
  17. The pH of pure water is 7, and the pH of soap is around 10.
  18. Hydrochloric acid in the stomach helps break down food and kill bacteria.
  19. A compound that produces hydroxide ions is called a base.
  20. The pH of most cells in the body is kept between 6.5 and 7.5.
  21. Organisms control pH through buffers.
  22. Buffers play an important role in maintaining homeostasis.
