Answer:

The correct option is A

Explanation:

Distillation is the process of separating two or more miscible substances based on there difference in boiling point. Here, the one with the lowest boiling point separates/distill first, followed by the one with the next (lower) boiling point. The constituent with the highest boiling point is left behind except in cases where impurities are in high amount and it is also made to distill (last).

Limonene has a boiling point of 176°C while carvone has a boiling point of 231°C, hence limonene will distill first from a caraway seed oil distillation due to its lower boiling point.

Answer:

Explanation:

Limonene has a boiling point of 176C and (+)-carvone has a boiling point of 231C.

In distillation, the temperature is gradually increased until one of the components begins to vaporizes out of the solution. This vapor is then condensed into a different container. The component that vaporizes first will do so at a lower temperature than the second. Therefore, the component that has the lower boiling point will vaporize first.

How does the size of ions affect the conductivity of a solution?

mrs_skeptik [129]

Small ions have small areas. There is less resistance as they move through the solution.

For example, in molten salts, the conductivity of Li+ is greater than that of Cs+.

Small ions have high charge density.

Iodine 131, cesium 137, and strontium 90 are all considered isotopes. What are isotopes?

Nitella [24]

Answer:

Isotopes are variants of an element, where the number of neutrons is different but its number of protons stay the same.

Explanation:

If the number of protons had changed then it would just be a different element.

Electron number changing simply adds charge to the atom, and doesn't change it or anything.

According to the Arrhenius concept, an acid is a substance that ________. Group of answer choices can accept a pair of electrons

Schach [20]

Answer: an increase in the concentration of $H^+$ in aqueous solutions and is capable of donating one or more $H^+$

Explanation:

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions $(OH^-)$ when dissolved in water and an acid is defined as a substance which donates hydrogen ions $(H^+)$ in water.

According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.

According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.

Thus According to the Arrhenius concept, an acid is a substance that causes an increase in the concentration of $H^+$ in aqueous solutions and is capable of donating one or more $H^+$
