Answer:
b
Explanation:
orbital overlap electron densities.
What class is this for because it depends
Atoms are (stable) if it has (valence) electrons in its outer most energy level.
Fluorine needs one electron to fill its orbital shell. It needs 8 valence electrons
Answer:
Change in internal energy (ΔU) = -9 KJ
Explanation:
Given:
q = –8 kJ [Heat removed]
w = –1 kJ [Work done]
Find:
Change in internal energy (ΔU)
Computation:
Change in internal energy (ΔU) = q + w
Change in internal energy (ΔU) = -8 KJ + (-1 KJ)
Change in internal energy (ΔU) = -8 KJ - 1 KJ
Change in internal energy (ΔU) = -9 KJ
