Explanation:
Electron affinity is negative when energy is absorbed and it is positive when energy is released.
Electron affinity is defined as the energy released in adding an electron to a neutral atom in the gas phase.
It is a measure of the readiness of an atom to gain an electron.
In a reaction where energy is released, electron affinity is usually positive. These reactions are called exothermic reactions.
Endothermic reactions in which energy is absorbed have negative electron affinity values.

Answer:
diamond is denser because it is more tightly packed than coal
Explanation:
Since, some of the given sample is stuck inside and behind the pipet. Hence, there will occur a decrease in the percent of acetic acid.
This is because a decrease in concentration of the acid will also lead to a decrease in the amount of sample taken for the estimation. Since. lesser is the amount or concentration present lesser will be its analyte concentration.
For example, we took 10 mg of a pickel sample but 3 mg of the sample remain stuck in the pipet. This means we actually titrating a sample less than 10 mg.
Therefore, the analyte concentration in the pickel will also be less.
