The Ph scale can tell you if a substance is an acid a base or neutral by
a Ph scale runs from a Ph of 1-14. if a substance has a Ph less than 7 (Ph<7) the substance is said to be a an acid
if a substance has a ph greater than 7 (Ph>7) the substance is said to be a base
if a substance has a Ph equal to 7(Ph=7) the substance is said to be neutral
look at the chemical tables. but i believe it is A
Answer:
1.06 V
Explanation:
The standard reduction potentials are:
Ag^+/Ag E° = 0.7996 V
Ni^2+/Ni E° = -0.257 V
The half-cell and cell reactions for Ni | Ni^2+ || Ag^+ | Ag are
Ni → Ni^2+ + 2e- E° = 0.257 V
<u>2Ag^+ 2e- → 2Ag </u> <u>E° = 0.7996 V
</u>
Ni + 2Ag^+ → Ni^2+ + 2Ag E° = 1.0566 V
To three significant figures, the standard potential for the cell is 1.06 V
.
Bromine (Br) is the only element listed that is a diatomic element. I believe that Bromine is going to be your answer.
