32 electrons. as the orbitals get father away from the nucleus, they hold more electrons.

Answer:
a) cu2+ + 1Hg (l) 1Cl- equilibrium cu (s) + Hg2Cl2 (s)
b) 0.068 V.
Explanation:
A) Cu2+ + 2e- euilibrium cu (s)
Hg2Cl2 + 2e- equilibrium 2Hg (l) + 1cl-
Cell Reaction: cu2+ + 1Hg (l) 1Cl- equilibrium cu (s) + Hg2Cl2 (s)
B) To calculate the cell voltage
E = E_o Cu2+/Cu - (0.05916 V / 2) log 1/Cu2+
putting values we get
= 0.339V + (90.05916V/2)log(0.100) = 0.309V
E_cell = E Cu2+/Cu - E SCE = 0.309 V - 0.241 V = 0.068V.
Answer:
Oxygen is solvent and Helium is solute.
Explanation:
Helium is a complety inert gas which do not react with other compounds whereas, oxygen can take part in chemical reaction with many compounds.
- if we mix 15 mL of oxygen and 5mL of helium then the oxygen is the solvent and helium is solute.
- In a mixture the compound with the greater volume is solvent and the compound with lwss volume is solute.
- in this case, oxygen has greater volume than that of helium so oxygen is solute and helium is solvent here.
Answer:
a. n = 3
b. n = 4
Explanation:
n is just the number in front of the orbital, as n represents the energy level of the orbital.
