stealth61 [152]
According to the second law of thermodynamics, heat energy released by an organism is released into the <span>environment and unusable. This energy is also known as entropy which is defined as the tendency of things to be dispersed and spontaneous. This means that entropy is always random and becomes unavailable energy.</span>

A cr3+(aq) solution is electrolyzed using a current of 7.40
oee [108]
When Cr+3  + 3e-  → Cr(s)

So according to the charge formula:

charge Q = I * t 

when we have I (the current) = 7.4 a

and t (the time in seconds) = 1.85d * 24h * 60 min*60sec=  159840 sec

by substitution:

Q = 7.4 a * 159840 sec = 1182816 C

now to get the mass we have to use Faraday constant which is:

F = e NA

   = 1.602 x 10^-19 * 6.022 x 10^23

  = 96485 C mol^-1

when e is the electron charge & NA Avogadro's number for the charge in on mol 

and as we can see from the equation Cu3+ reacts with 3 electrons so,

the mass of Cr(s) = Q* (1mole-/F) * (1molCr / 3 mol e-)

                            = 1182816 * (1/96485) * (1/3)

                            = 4.1 g
