pretty positive the answer is 1
A resonance dot structure refers to the electrons that are able to switch position. For example Benzene is a resonance structure. It comes down to Pi bonds and how the free electrons are able to move around within a double bonded structure.
Answer:
The solubility of a substance in water increases as the temperature rises, especially for gases.
The solubility of a substance in water with temperature generally increases for ionic solids.
Explanation:
Solid substances dissolved in liquid water, the solubility increases with temperature. Gases tend to naturally have high entropy or kinetic energy than solid substances so the same still applies.
This phenomenon is due to the increase in kinetic energy acquired by the particles of the solid at higher temperatures which allows the solvent molecules to effectively break apart the solute molecules that are held together by intermolecular attractions
Answer: B. It is an ether because it is unable to to form a hydrogen bond, so it is less soluble than water
Explanation: Alcohols 
are more soluble in water as they can form hydrogen bonding with water whereas ethers 
are less soluble as they do not form hydrogen bonds with water.
For formation of hydrogen bond, the electronegative atom (F, Oand N) must be attached to hydrogen and in ethers (ROR), there is no hydrogen directly attached to electronegative oxygen atom, thus are less soluble in water.
