Answer:
True.
Explanation:
The boiling point of acetone is 56°C while boiling point of 2-methyl propane is -11°C. Based on these values, <em>boiling point of acetone is much greater than the boiling point of 2-methylpropane. </em>
That could be because acetone has an electronegative atom (Oxygen) doing high intermolecular forces in this molecule while 2-methylpropane is an apolar molecule.

Answer:
Photosynthesis removes carbon from the atmosphere, and cellular respiration releases carbon back into the atmosphere.
Explanation:
The first option clearly expresses the relationship between photosynthesis and cellular respiration.
Cellular respiration releases carbon back into the atmosphere whereas photosynthesis removes the carbon from the atmosphere.
Photosynthesis is the process whereby green plants manufacture their food using carbon dioxide and water.
In cellular respiration, the product of the photosynthesis is used by organisms to produce energy.
The number that would be in the place of x and Y is
x=2
Y=1
Hence the formula will be K2Se
Explanation
When K+ which is positively charged combine with selenide (se2-) which is negatively charged they form an ionic bond K2Se.
- 2 potassium ions K+) loses 1 electron each while selenide ion (Se2-) accept the 2 electron, Hence the formula of ionic bond is K2Se
<span>The best answer is that it would be a gas instead of a liquid, but this isn't one of the choices. I suppose the next best is that it would not expand when it freezes.</span>
