Poor water quality has its most direct impact on aquatic wildlife. Such as fish, bugs, and plants
C I’m pretty sure that is the answer
Explanation:
Formula for energy value is as follows.
E = 
where, 
= 13.6
n = number of shell
So, at ground state energy of hydrogen atom will be as follows.
E =
= 
= -13.6
Hence, for an ionized atom value of energy will be as follows.
E' = 
or, E' = 
Thus, we can conclude that total energy of the remaining electron in the ionized atom is .

you are welcome
Answer:
1.070MKCl
Explanation:
So we know that the original formula is M= n/L (n being moles of solute, L being liters of solvent)
Since we do not have liters in this problem, we would need to convert milliliters to liters
<u>213 mL= 0.213 L</u>
We then see that we do not have moles, but we do have a mass, being <u>17.0 g.</u> we would need to convert these grams to moles, giving us <u>0.228 mol.</u>
Then, you would plug in <u>0.228 for your n</u>, and now you are ready to solve your original formula, plugging everything in.
M=n/L
M=0.228 mol/0.213L
M= 1.070MKCl
I know this was long, but I hope this helps (:
