Hypochlorous acid is a weak acid. The
value for the dissociation of HOCl is 
Answer: There are
atoms in 24 moles of Fe.
Explanation:
According to the mole concept, 1 mole of a substance contains
atoms.
Therefore, atoms present in 24 moles of Fe are calculated as follows.

Thus, we can conclude that there are
atoms in 24 moles of Fe.
This is a simple chemical change due to what it produces and how it is added together. Hope this helps.
Answer:
Correct choice are C and D (they are both, the same).
Explanation:
Cathode is the positive(+) electrode where a reduction occurs.
Reduction is the chemical reaction where the oxidation state is reduced.
2Ag(s) + 1/2 O2(g) + 2H+(aq) → 2Ag+(aq) + H2O (l)
A. 2H2O (l) → O2 (g) + 4H+ (aq) + 4e-
B. 2Ag (s) → 2Ag+ (aq) + 2e-
C. 1/2 O2 (g) + 2H+ (aq) + 2e- → H2O (l)
D. 1/2 O2 (g) + 2H+ (aq) + 2e- → H2O (l)
C or D, are ok. They are the same equation.
Oxygen from ground state reduce the oxidation state from 0 to -2
