<h3>0.76 V</h3><h3 /><h3>The voltmeter shows that the standard cell potential of a galvanic cell consisting of a SHE and a Zn/Zn2+ couple is E°cell = 0.76 V.</h3><h3 />
The concentration of a cell is generally 0.15 M (0.9 % NaCl)
As given the solution has concentration = 200mm = 0.02 M
This concentration of solution is less than the concentration of cell
Hence solution is hypotonic (less concentration) and cell will be hypertonic
Correct Answer: Option C
Reason:
Amines are <span>organic compound obtained from ammonia by replacement of one or more hydrogen atoms by organic groups.

If one of the 'H' atom of NH3 is replace by R = alkyl group, they are referred as primary amine. If two 'H' atoms of NH3 are replace by same or different alkyl group, they are referred as secondary amine. If all the three 'H' atom of NH3 are replace by same or different alkyl group, they are referred as tertiary amine.
In present case, option C has 2 'H' atoms of NH3 replaced by alkyl group. Hence it is secondary amine.
Answer: 0.4
Explanation: The easiest way to do this is to get a denominator of 10. To do this, multiply each number in 2/5 by 2. You will get the fraction 4/10. With the denominator of 10, the answer would be 0.4 by putting the decimal in front of the number.
