The H3O+ concentration of the solution with a PH of 3.60 is 2.5 x10^-4 M (answer A)
<u><em>explanation</em></u>
PH is calculated using PH = - log [ H3O+] formula
Therefore - log [H3O+] = 3.60
To calculate the concentration of h3O+ ,find the antilog of 3.60
Since -log is at base of 10, the antilog of 3.60 = 10^-3.60 = 2.5 x10^-4M
Since the chemical definition of "stable" means close to having a full valence shell, the answer is 3d^10.

Answer: Option C) 4 moles
Explanation:
The reaction below shows the decomposition of 2 moles of water to yeild 2 moles of hydrogen and 1 mole of oxygen respectively.
2H2O(l) --> 2H2(g) + O2 (g)
So, if 2 moles of H2O produce 1 mole of O2
8 moles of H2O will produce Z mole of O2
To get the value of Z, cross multiply
2 x Z = 1 x 8
2Z = 8
Z = 8/2
Z = 4
Thus, 4 moles of O2 is produced from the complete decomposition of 8 moles H2O .
The correct answer is option B.
