According to the beer-lambert law when its concentration increases so does the absorbance increase.
beer-lambert law states that the amount of energy absorbed or transferred by a solution is proportional to the molar absorptivity of the solution and the concentration of the solute.
This means that concentrated solutions absorb more light than dilute solutions.
so the According to the beer-lambert law concentration increases, so does the absorbance. Therefore, absorbance is directly proportional to concentration.

This is an exception to the general electronegativity trend. It can be explained by looking at the electron configurations of both elements.

When you remove an electron from beryllium, you are taking away an electron from the 2s orbital. When you remove an electron from boron, you are taking an electron from the 2p orbital. The 2p electrons have more energy than the 2s, so it is easier to remove them as they can more strongly resist the effective nuclear charge of the nucleus.
Answer:
A and B as well C are the compounds.
Explanation:
- A seems to be a compound, very least, it appears to contain carbon and oxygen.
- C seems to be a compound, containing respectively oxygen as well as carbon.
- B isn't always described by that of the information provided, it is therefore presumably a compound because there are few components as white solid particles.
So that the above is the correct answer.
<span>Heat would make the molecules move faster so they would spread out therefore making air less dense.
Less dense means less packed. Heat increase the kinetic energy</span>
