Explanation:
The given reaction at cathode will be as follows.
At cathode: , = -0.761 V
At anode: , = 0.761
Therefore, net reaction equation will be as follows.
Initial: 0.129 - - 0.427
Change: -0.047 - - -0.047
Equilibrium: (0.129 - 0.047) (0.427 - 0.047)
= 0.082 = 0.38
As for the given reaction is zero.
Hence, equation for calculating new cell potential will be as follows.
E_{cell} =
=
= 0.019
Thus, we can conclude that the cell potential of the given cell is 0.019.
Answer:
4 tabletes/dose
Explanation:
mass person = (90 Lb)×(Kg/2.20462 Lb) = 40.823 Kg body
amount of medicine = 50 mg/Kg body.day
frecuency = 2 dose/day
⇒ amount of medicine/day = (50 mg/kg body.day)×(40.823 Kg body) = 2041.168 mg/day
⇒ mg medicine/dose = (20141.168 mg/day)×(day/ 2 dose) = 1020.584 mg medicine/dose
∴ mg medicine/tablet = 250 mg medicine/tablet
⇒ # tabletes/dose = (1020.584 mg medicine/dose)×(tablet/250 mg medicine) = 4.082 tabletes/dose
⇒ # tabletes/dose ≅ 4 tabletes/dose
The answer for this is true
To Find :
The STP moles of 67.2 L CO.
Solution :
We know, molar volume at STP is used to converted into moles by :
1 moles = 22.4 L STP
So, number of moles in 67.2 L CO is :
Therefore, number of STP moles are 3.
Hence, this is the required solution.
Density =
volume = (4.5 cm) * (5.2cm) * (6.0cm)
= 140.40 cm³
since Mass = 1591 g
then Density =
= 11.33 g/cm³
