Observe: Set up the Gizmo to observe freezing. What do you notice about the temperature while the water is in the process of fre
kaheart [24]

Answer:

In cases where the water freezes, a release of energy occurs to the environment, therefore energy is lost, and it begins to "cool down".

The term cooling in chemical science today is not well seen since it is not considered that this exists, but would be replaced by the term "absence or loss of heat".

It is considered that a body cools when its temperature decreases, and if it continues to decrease as in the case of water, a point will reach the freezing point, which in this case that of water is 0 degrees Celsius, therefore when the cooling overcomes this thermal barrier the water solidifies "freezing"

Explanation:

In the case of pure water (H2O), the freezing point is 0 ° C. This means that, as long as it is at a temperature above 0ºC and below 100ºC (since that is its boiling point), the water will be in a liquid state.

Use molecular orbital theory to determine the ground state electron configuration of f2 and f2+
Ronch [10]

Atomic number of F = 9

Electron configuration of F:-

⁹F = 1s² 2s² 2p⁵

Incase of F2: Total electrons: 9 + 9 = 18

For F2 the ground state electron configuration would be:

F2 = (1σ)²(1σ*)²(2σ)²(2σ*)²(2pσ)²(2pπ)⁴(2pπ*)⁴

Incase of F2+: There is loss of one electron from neutral F2. Total electrons: 18-1 = 17

For F2+ the ground state electron configuration would be:

F2 = (1σ)²(1σ*)²(2σ)²(2σ*)²(2pσ)²(2pπ)⁴(2pπ*)³
