Lab 10.1

1. The sugar and salt samples are polar because they were not soluble in hexane, and because they were both sulble in water and ethanol. 
2.The vegetable oil is the only non-polar sample because we found that it was soluble in hexane.
 3.We concluded that polarity in ethanol isn't not at a constant rate because it did not dissolve both non-polar or polar molecules at the same rate for a same amount of time.
 4.I would not expect ethanol to dissolve in any of the other two solutions because of its polarity.
 5.NH3: polar, soluble, insoluble. I2: non polar, insoluble, soluble. HCl: polar, soluble, insoluble.
6. The ionic materials are polar whereas hexane is non-polar, therefore the compounds dissolve together.

Enrichment:
I think only the carbon dioxide would dissolve because out of the three gases,due to the fact it's the only polar compound. Oxygen and carbon dioxide need to be able to dissolve in water for any life to live because it's what they use to breathe.
