In a college of exactly 2760 students, exactly 65 % are male. What is the number of female students? Express your answer as an i
1 answer:
Total number of students (male and female) in the college=2760. Total number of students including both male and female represents 100% (percentage) of students which is equal to 2760 number.
Number of male students is 65% (percentage) which is equal to = 1794. So, total number of female students are (100-65)%=35% (percentage) which is equal to
=966 numbers.

<u>Answer:</u>
<u>For A:</u> The standard cell potential of the reaction is 4.4 V
<u>For B:</u> The standard Gibbs free energy of the reaction is
<u>For C:</u> The reaction is spontaneous as written.
<u>Explanation:</u>
- <u>For A:</u>
The given chemical reaction follows:
The given half reaction follows:
<u>Oxidation half reaction:</u> ( × 2)
<u>Reduction half reaction:</u>
The substance having highest positive potential will always get reduced and will undergo reduction reaction.
Here, chlorine will undergo reduction reaction will get reduced.
Substance getting oxidized always act as anode and the one getting reduced always act as cathode.
To calculate the of the reaction, we use the equation:
Hence, the standard cell potential of the reaction is 4.4 V
- <u>For B:</u>
Relationship between standard Gibbs free energy and standard electrode potential follows:
where,
n = number of electrons transferred =
F = Faradays constant =
= standard cell potential = 4.4 V
Putting values in above equation, we get:
Hence, the standard Gibbs free energy of the reaction is
- <u>For C:</u>
For a reaction to be spontaneous, the standard Gibbs free energy change of the reaction must be negative.
From above, the standard Gibbs free energy change of the reaction is coming out to be negative.
Hence, the reaction is spontaneous as written.
