The density if water would still be the same if measured in a 1/4 cup of water or in a 1/2 cup of water. The constant value of water's density is 1.00 g/cm^3.

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

the first three ionization energies of an element x are 590, 1145, and 4912 kj mol-1. what is the most likely formula of the com
joja [24]

<u>Answer:</u> The chemical formula is XSO_3

<u>Explanation:</u>

Ionization energy is defined as the amount of energy that is required to remove an electron from a chemical species.

The ionization energy equation for the given values follow:

X(g)\rightarrow X^+(g)+e^-;E_I=590kJ/mol

X^+(g)\rightarrow X^{2+}(g)+e^-;E_I=1145kJ/mol

X^{2+}(g)\rightarrow X^{3+}(g)+e^-;E_I=4912kJ/mol

From the values of ionization energy above, it can be seen that the ionization energy increases as every succeeding electron is removed.

Second ionization energy is a little higher than the first one but there is a huge amount of difference between the third and second ionization energy.

This implies that the ion formed during second ionization energy has a stable configuration and it requires a humongous amount of heat to release the third electron.

Hence, the ion formed will be X^{2+}

Sulfite ion is a polyatomic ion having a chemical formula of SO_3^{2-}

An ionic compound is formed between the two ions and the chemical compound formed between the two will have a formula of XSO_3

Hence, the chemical formula is XSO_3

A chemist has a small amount of compound ( b.p. = 65 oC) that must be fractionally distilled. Yet, the Chemist does not want to
koban [17]

Answer:

The chemist can either:

a. Use a small fractionation apparatus.

b. Add a compound with a much higher boiling point.

Explanation:

Using a smaller fractionation apparatus or Vigreux column will help to minimize loss of the distillate.

If a compound with a higher boiling point is added, the vapors of this liquid will displace the vapors of this small amount of compound with a lower boiling point. This compound with a higher boiling point is known as a Chaser.
