Answer:
<h3>The answer is 5.0 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 100 g
volume = 20 mL
So we have

We have the final answer as
<h3>5.0 g/mL</h3>
Hope this helps you
Answer:
Option a. Benzenecarbonitrile
Explanation:
You are not providing the picture of the compound. However, I manage to find the picture of it, so I'm gonna answer this with the picture. Its attached here at the end.
As for the IUPAC name of this compound, it would be Benzenecarbonitrile, or simply, benzonitrile.
This compound has the molecular formula C₆H₅CN. It receives this name over the other ones, because this is a aromatic cyanide, and aromatic cyanide has nitriles behavior, (Strength of the nitrogen over the carbon), therefore, this group has priority over the whole molecule. As the principal chain is the benzene, the carbonitrile is the radical of the group, and when cyano groups are as radical and not as principal chains, it has a behavior of nitrile, and it's named as nitrile. therefore, option b, cannot be the name.
phenylcyanide is naming the phenyl as radical, but the benzene is the principal group in this compound, and the cyanide is the radical. It happens the same thing with cyanophenyl.

It is true that when a distance between gas particles increases, the volume of the gas will also increase.
Answer: Option A
<u>Explanation:</u>
The volume of any material can be the space occupied by any material. And the space required by any material to occupy a desired shape or size is determined by its bonding and distance between the particles making that material. If the particles which are soft and small can be compressed easily to occupy very small volume compared to compound made up of hard and large particles.
Along with this, the distance between the neighbouring particles also play a major role, as if we consider a laddo, we can compress it to small size by reducing the distance between neighbouring particles while we will not be able to compress the size or volume occupied by a table as we cannot reduce the distance of particle separation. Thus, it is true that if the distance between gas particles increased then the volume of gas particles will also increase.
Answer:
C
Explanation:
energy is measures the capacity to do work.
Answer:
None of these statements are true
Explanation:
(a)
Heavier and large molecules or atoms exhibit greater dispersion force than lighter ones due to easily form temporary dipoles by large molecule.
(b)
Compounds with hydrogen bonding usually have higher boiling point than that of similar compound without hydrogen bonding,
Because boiling point of a compounds depends on force of attraction between the molecules.
(c)
Non polar compounds usually have lower boiling points than polar compounds of similar mass due to dipole dipole attractive force of polar compound.
