<u>Answer:</u>
<em>The energy to turn the ice into water:</em>
- The energy that is required to change the state of ice into a liquid is obtained in the form of heat energy from the ambient temperature of the warm room.
- Once this heat energy is absorbed, the individual molecules of ice gain kinetic energy and start vibrating faster.
- Yet, the temperature of the ice remains constant until the ice reaches its melting point because this energy is first utilised to break all the bonds of the lattice structure of the ice.
- After all the bonds are broken and all of the ice has changed into water, if more heat is provided again, then the temperature of the water will increase.
The answers to the questions are as follows;
- It would gain three electrons
- The difference in their electronegativities.
- The elements have filled Valence levels
- potassium (K) with a 1+ charge
- 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-
Answer: The one listed below that's NOT an example of potential energy is mechanical energy. Mechanical energy is categorized as a kinetic energy with light, sound, and thermal/heat energy.
