Which of the following represents an electron configuration that corresponds to the valence electrons of an element for which there is an especially large jump between the second and third ionization energies? A. ns^2
B. ns^2np^1
C. ns^2np^2
D. ns^2np^3

C

Explanation:

I'd assume it would be C because the two electrons present in the l = 2 subshell (p) are degenerate. As a result the energy needed to remove an electron in a lower subshell (l=1) would be substantially different compared to the other subshell.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
