Chemistry electrolysis?
Metallic magnesium can be made by the electrolysis of molten MgCl2.
(a) What mass of Mg is formed by passing a current of 6.75 A through molten MgCl2 for 3.88 days? in grams
(b) How many minutes are needed to plate out 10.00 g Mg from molten MgCl2 using 2.50 A current?
Answer:
Mass of Mg = (6.75*86400*3.88)*24/96500 = 562.772891 g
b) time = 10*96500/(24*2.5) = 16 083.3333 secondsHow many ml of 0.25 N H2SO4 would it take to neutrazlize 50 ml of 0.30 N NaOH?
