Across
  1. 5. A molecule that has slight positive and negative charges due to an imbalance in the way electrons are shared.
  2. 6. The phenomena that occurs when individual molecules are so strongly attracted to each other that they tend to stay together, even when exposed to tension.
  3. 9. The type of liquid that will dissolve a nonpolar substance.
  4. 10. Water that has certain dissolved ions in it.
  5. 12. A molecule that has no overall charge because there is not an imbalance in the way electrons are shared.
  6. 14. The 2 types of substances that water will dissolve.
Down
  1. 1. The reason water is a liquid at room temperature when all other chemically similar substances are gasses at room temperature. This also makes the surface tension of water larger than that of many other substances.
  2. 2. The property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of its molecules.
  3. 3. A possible cause for when an experiment does not work perfectly.
  4. 4. A liquid substance capable of dissolving other substances.
  5. 7. The chemical formula for water
  6. 8. The use of electricity to break a molecule down into smaller units.
  7. 11. The substance added to a water softener that helps it do its job.
  8. 13. A substance that is dissolved in a solvent.
