Answer:
What is true of a solution of 1.0 M HCl(aq)? It contains 1.0 gram of HCl per 100 grams of water.
Explanation:
The anode is the electrode where the oxidation occurs.
Cathode is the electrode where the reducction occurs.
Equations:
Mn(2+) + 2e- ---> Mn(s) Eo = - 1.18 V
2Fe(3+) + 2e- ----> 2 Fe(2+) 2Eo = + 1.54 V
The electrons flow from the electrode with the lower Eo to the electrode with the higher Eo yielding to a positive voltage.
Eo = 1.54 V - (- 1.18) = 1.54 + 1.18 = 2.72
Answer: 2.72 V
Answer:
Following are the answer to this question:
Explanation:
The most stable carbocation is: 
- The means of
is a hydrocarbon with
, which is needed to find the double bonds.
- The formula for calculating the unsaturation hydrocarbons are:
Degree of the unsaturation

Where,
C=9, N=0, X=0, H=12


which means 3 double bonds and 1 ring.
