There are certain processes in nature that produce many of these radioactive<span>isotopes. For instance, some </span>radioactive<span> nitrogen is produced in the atmosphere when high energy cosmic radiation from the sun hits the earth. Other </span>radioactive<span>isotopes are only available by artificial production. good luck</span>
It is a subscript
Also do you mean Cl not Ci. I assume you do because then it means 4 chlorine in that compound.
Explanation:
Let us assume that the concentration of [
and 
is equal to x. Then expression for 
for the given reaction is as follows.
![K_{w} = [OH^{-}][H^{+}]](https://tex.z-dn.net/?f=K_%7Bw%7D%20%3D%20%5BOH%5E%7B-%7D%5D%5BH%5E%7B%2B%7D%5D)
Now, we will take square root on both the sides as follows.
![[H^{+}] = 8.2 \times 10^{-8}](https://tex.z-dn.net/?f=%5BH%5E%7B%2B%7D%5D%20%3D%208.2%20%5Ctimes%2010%5E%7B-8%7D)
M
Thus, we can conclude that the 
concentration in neutral water at this temperature is 
M.
There are no numbers provided so I will try to explain the equation. If you want to find the percent error you would do theoretical (the number it’s supposed to be) minus experimental (the number you got in the experiment) over the theoretical value (same as the first one.) You must multiply this by 100 in order to show the actual percentage rather than very low decimals. You want the percent error to be as low as possible because the lower it is the less mistakes happened. Mistakes can include too much/less of solvent, solution, or the glassware wasn’t clean enough, and much much more.
I hope this helps!
Please mark the brainliest if it does! (:
Answer: B2H6 (g) + 3O2 (g) → B2O3 (s) + 3H2O (g) (ΔH = -2035 kJ/mol) 3H2O (g) → 3H2O (l) (ΔH = -132 kJ/mol) 3H2O (l) → 3H2 (g) + (3/2) O2 (g) (ΔH = 858 kJ/mol)
