<u>Answer:</u> D. the ionic compound calcium fluoride $(CaF_2)$

The correct option here is the fourth one.

<u>Explanation:</u>

Salt like compounds addition to water is likely to be inducing certain changes in temperature of freezing into solid and also alter the temperature of boiling.

It is noticed that addition of salts in water mostly tends to get lower the freezing temperatures from the original freezing point of water and among the given 3 options calcium fluoride tends to lower the freezing point most when compared to others.

Thus as vant hoff factor is highest factor for $CaF_{2}$ and the freezing point will be lowest.

Answer:

Explanation:

This signifies a defect in mass. The phenomenon is known as mass defect. Mass defect is compares the mass of an isotope to that of the nucleons in the nucleus.

The mass defect implies the energy that was given off when the protons and neutrons combine to form the new helium atom. The mass defect helps us to understand why the mass of an atom might not eventually correspond to what we obtain theoretically by calculation.

Explanation:

In DNA, A=T, C=G, and vice versa. RNA has U instead of T. So dna to rna: adenine = uracil, thymine = adenine, cytosine = guanine, and guanine = cytosine.
