Answer:
The volume of the stock solution needed is 1L
Explanation:
Step 1:
Data obtained from the question. This include the following:
Concentration of stock solution (C1) = 6M
Volume of stock solution needed (V1) =?
Concentration of diluted solution (C2) = 1M
Volume of diluted solution (V2) = 6L
Step 2:
Determination of the volume of the stock solution needed.
With the dilution formula C1V1 = C2V2, the volume of the stock solution needed can be obtained as follow:
C1V1 = C2V2
6 x V1 = 1 x 6
Divide both side by 6
V1 = 6/6
V1 = 1L
Therefore, the volume of the stock solution needed is 1L
Answer:
an atom is the basic unit of a chemical element.
a particle is a minute portion of matter.
Answer:
See explanation
Explanation:
i) Oxidation half-reaction:
2Ag(s) ----> 2Ag^+(aq) + 2e
Reduction half-reaction:
Ni^2+(aq) + 2e ----> Ni(s)
ii) Ag is the anode while Ni is the cathode
iii) E°cell = E°cathode - E°anode
E°cell = (-0.25) - (0.80)
E°cell = -1.05 V
iv) This is an electrolytic cell since the cell reaction is non spontaneous.
