Explanation:
element with atomic numbers 7 and 83 have 5 and 5 valence electrons
B, I would believe. There are 58, but B is the closest we can get.
I think the answer is B. the sum of the enthalpy changes of the intermidiate reactions
The concentration of the hydroxide ion given that the concentration of the hydronium ion 1.0 times 10^-14 M. The reverse mathematical method used to determine the pOH can be used to get the hydroxide ion concentration from the pOH. How many hydroxide ions are there in a solution with a pOH of 5.70, for instance.
Calculate 10-5.70, or "inverse" log, on a calculator (- 5.70). It indicates that one hydroxide ion is produced by one part of the NaOH solution. Because of this, the molar concentration of hydroxide ions in the solution is the same as the molar concentration of the NaOH.
