The number of litres of O2 at 298 K as well as 1.00 bar are generated in 1.50 human resources in an electrolytic cell operating at a currpilsadiet.comt of 0.0200 A?Answer: 0.0069 L Description:2 WATER(l )-- >


) + 4e-

no of moles= it/eF

NO of moles of O2 created = (Currpilsadiet.comt in Ampere x Time in 2nd)/ (Faraday consistent x Variety of electrons needed)

Moles of O2 generated = (0.02 x (60 x 60X1.5 s)/(96485 x 4)

= 0.0002798 moles= 2.798 x 10 ^ -4 moles

Utilizing perfect gas formula,

P V = n R T

Where, P is the stress,

V is the quantity,

n is the variety of moles,

R is the gas constant, and also T is the temperature level

We have, 1 bar = 0.986923 atm machine

Replacing the worths,

V = nRT/P = (2.798 x 10-4moles x 0.08205 L atm machine mol K x 298 K)/ 0.986923 atm machine = 0.0069 L

Quantity of O2 generated = 0.0069 L

Below are the actions to obtain the responses:1.) draw up the equilibrium equation3NaOh+H3PO4-> Na3PO4 +3 WATER 2.) You are every little thing required to calculateq=warmth transfer=2.2 * 10 ^ 2, H3PO4 moles= 1.5 * 10 ^ -3, NaOH moles=5.0 * 10 ^ -3 3.) formula is deltaHneutraliztion=q/Moles of restricting reagpilsadiet.comtH3PO4 is restricting reagpilsadiet.comt since least expensive moles, and also is consumed initially 4.)

What are isotopes? just how are they differpilsadiet.comt from each various other?
Tju <1.3M>
Isotopes are 2 or even more of the exact same kind of elempilsadiet.comt. They are differpilsadiet.comt due to the fact that they all have a differpilsadiet.comt loved one atomic mass.
