Answer 1

Answer #1

From the law of electrolysis-

(i×t)/96500=equivalent of substance

Equivalent of Ba= weight of Ba/equivalent weight of Ba

Equivalent of Ba= 16/68.665=0.233

So , (i×t)/96500=0.233

15×t=96500×0.233

t=1499.06 second = 25minute

So required time is 25 minute

Please give thumbs up. Thank you

Problen 1 1. For production of penicillin (CIGHsO4N S, molecular weight 334.4 g/mol), glucose CoHr2O) is used as substrate and phenylacetic acid (C H O2) is added as precursor. The stoichiometry for overall synthesis is: A supply of 100 mol/hr of glucose is fed to a continuous stirred-tank reactor for the production of penicillin, along with 200 mol/hr of ammonia (NHs),130 mol/hr of oxygen, 125 mol/hr of sulfuric acid and 100 mol/hr of phenylacetic acid. a. Determine the limiting reactant...

Microscale techniques: In today's experiment we will be using very small amounts of chemical reactants. This method is generally less expensive and more environmentally-friendly than traditional "test tube" chemistry. Some of the waste products produced in today's experiment, particularly those containing lead and barium, are harmful to the environment. By using such small amounts of chemical reactants we generate far less waste than by using larger scale methods. Procedure 1. Put on your safety goggles. Be sure to wear them...

Hi, can anyone please help me with this? i have no clue how to define if a reaction is Oxidation reduction or not. Thanks a lot OXIDATION-REDUCTION Introduction Chemists refer to reactions which involve a transfer of electrons from one reactant to another as oxidation reduction reactions of just "redox" reactions. Oxidation is defined as a loss of electron and reduction as a gain of electron by a substance during a chemical reaction. The loss of electrons by one substance...
