How would the electron configuration of nitrogen change to make a stable configuration?
AnnZ [28]

The answers to the questions are as follows;

  1. It would gain three electrons
  2. The difference in their electronegativities.
  3. The elements have filled Valence levels
  4. potassium (K) with a 1+ charge
  5. ClO-

Question 1:

  • How would the electron configuration of nitrogen change to make a stable configuration?

Since Nitrogen has 5 Valence electrons, it needs 3 electrons to attain it's octet configuration. As such, it gains 3 electrons.

Question 2:

  • Which quantity determines how two atoms bond.

The quantity which determines how two atoms bond is The difference in their electronegativities.

Question 3:

  • Which statement best explains why the elements in Group 18 do not have electronegativity values.

This is because the elements have filled Valence levels.

Question 4:

  • Based on patterns in the periodic table, which ion has a stable valence electron configuration

The ion which has a stable Valence electron configuration is potassium (K) with a 1+ charge

Question 5;

  • Which chemical formula represents a polyatomic ion?

The chemical formula which represents a polyatomic ion is; ClO-

If 3 moles of a compound use 24 J of energy in a reaction, what is the A<br> Hreaction in J/mol?
erma4kov [3.2K]

Answer:

+8 J/mol

Explanation:

The following were obtained from the question:

Mole of the compound = 3 moles

Heat Energy used = 24J

Hreaction =?

The heat of reaction is the energy released or absorb during a chemical reaction. It is can obtained mathematically by the following equation:

Hreaction = Heat energy/mole

With the above equation, we can easily find the Hreaction for the question given as follow:

Hreaction = Heat energy/mole

Hreaction = 24J / 3mol

Hreaction = 8 J/mol

Since the compound used the energy, the Hreaction is +8 J/mol
