Answer:
E° = 2.46 V
Explanation:
We have a voltaic cell of aluminum and silver in their respective solutions. To know where will take place the reduction (cathode) and where will take place the oxidation (anode), we need to compare the standard reduction potentials.
E°(Al³⁺/Al) = -1.66 V
E°(Ag⁺/Ag) = +0.80 V
Since Ag⁺/Ag has the highest reduction potential that is where reduction will take place while oxidation will take place in the Al electrode.
Reduction (cathode): Ag⁺(aq) + 1 e⁻ ⇒ Ag(s)
Oxidation (anode): Al(s) ⇒ Al³⁺(aq) + 3 e⁻
The standard potential of the cell (E°) is the difference between the reduction potential of the cathode and the reduction potential of the anode.
E° = E°red,cathode - E°red,anode = 0.80 V - (-1.66V) = 2.46 V
Answer:
Heating Fan is 75.33% efficient.
Explanation:
As it is mentioned that the given fan is a HEATING FAN, it means the it is used for provided heat (thermal energy) to the surrounding. Hence, its efficiency depends upon how much heat/thermal energy is provides.
We can state that.
Total Energy provided = 150 J
Useful Energy = 113 J
Wasted Energy = 37 J
The efficiency of the heating fan can be given by following formula:
Efficiency = ( Useful Energy / Total Energy ) × 100
Efficiency = ( 113 J / 150 J) × 100
Efficiency = (0.7533)× 100
Efficiency = 75.33%
