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 bu

bbles leave the water, but after a little while, the bubbles stop. As you keep applying the vacuum , more bubbles appear. A friend 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. Another friend 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? What, then, is responsible for the second batch of bubbles?

Answer:

The second friend is mostly correct.

Explanation:

When pressure decreases, gas solubility decreases. The bubbles are gas molecules that were dissolved in the water at atmospheric pressure. The bubbles started coming out as a result of the decrease pressure. The second bubbles would be water vapor because as the pressure continue to decrease, the amount of vapor pressure  ( vapor leaving the surface of the liquid ) equals the external pressure and water begin to boil. So the second bubbles must be water vapor.

What is the name for a substance made of billions of oppositely charged ions<br> joined together?
bija089 [108]

Answer:

Ionic substance

Explanation:

An ionic substance is formed when oppositely charged ions link up to form an infinitely large lattice structure that can only be described in terms of unit cells.

Ionic substances may consist of billions of oppositely charged ions. Ionic substances are hard, have high melting and boiling points and do not conduct electricity in the solid state because the ions are not free in the solid state.

However, in solution or molten state, the substance conducts electricity since the ions which are the charge carriers are now mobile.
