Answer:
Solid ionic compounds do not conduct electricity because the ions are held firmly in place. The ions cannot move to conduct the electric current. But when an ionic compound melts, the charged ions are free to move. Therefore, molten ionic compounds do conduct electricity.
Answer:
9-10 ppm.
0.2-0.4 ppm.
Explanation:
The proton on the aldehyde group will appear at approximately 9-10 ppm whereas the methylene peak on the alcohol is the only peak 0.2-0.4 ppm for either compound. Aldehydes and aromatics are quite distinctive in the Nuclear magnetic resonance (NMR). Aldehydes show up from 9-10 ppm, usually as a small singlet; aromatic protons show up from 6.5-8.5 ppm. NMR spectroscopy is the use of NMR to study the physical, chemical, and biological properties of matter.

hope this helps,, have a nice day :))
Gases
Explanation:
Gases are the highly compressible states of matter made up of tiny particles that are moving independently of one another and are present in large quantities on the earth surface.
There are three states of matter which are solid, liquid and gas.
- The particles of a gas are very far apart and are held together by very weak attractive forces.
- In a gas, the molecules are in continuous, random, straight -line motion
- They are easily compressible due to the weak attraction between them.
