30) You take a sample of water that is at room temperature and in contact with air and put it under a vacuum. Right away, you see bubbles leave the water, but after a little while, the bubbles stop. As you keep applying the vacuum, more bubbles appear. Friend1 tells you that the first bubbles were water vapor, and the low pressure had reduced the boiling point of water, causing the water to boil. Friend2 tells you that the first bubbles were gas molecules from the air (oxygen, nitrogen, and so forth) that were dissolved in the water. Which friend is mostly likely to be correct? Friend1 Friend2 Both of them is correct. Both of them is wrong. 29) A molecular-level representation of a solution is shown. Is the solute an electrolyte or a nonelectrolyte? electrolyte nonelectrolyte neither an electrolyte nor a nonelectrolyte
