A spoon was silver-plated electrolytically in a AgNO3 solution. If 0.750 g of Ag was deposited on the spoon at a constant current of 20.0 mA, how long (in hours) did the electrolysis take? (1 mA = 1x10–3 A) 11.9 hr 9.32 hr 5.92 hr 8.76 hr 10.1 hr
a. For the electrolysis of molten BaCl2, diagram a cell. Include the direction in which a battery would be placed to power the cell. Write out half-reactions. Label flow of electrons, anode, cathode, indicate what is formed at each electrode (assume electrodes are generic metal). Could this reaction be carried out in aqueous solution? Why or why not (justify numerically). b. 0.67 g of Ag is deposited electrolytically from AgNO3after a certain period of time when subjected to a 12A...

Consider a process of electrolysis of Ag from AgNO3 solution with a constant current of 16 A. Determine time (in minutes) required to coat one side of a 10x10 cm square plate with Ag if the required coating thickness is 0.27 mm. (Density of Ag is 10.5 g/cm ; assume that the coating covers the surface homogeneously; round your answer up to one decimal place).
How many seconds would it take to deposit 17.3 g of Ag (atomic mass = 107.87) from a solution of AgNO3 using a current of 10.00 amp? a) 3.09 x 103 s b) 7.74 x 102 s c) 4.64 x 103 s d) 1.55 x 103 s e) 5.16 x 102 s
if 0.00594 moles N2O (g) effuses through an orifice in
a certain period of time, how much NO2 (g) would effuse in the same
time under the same conditions?
this is my work but Im not sure if I did it correctly. Could
someone tell me if i did it correctly and show me a step by step of
how
they did it?

A. How many moles of Al can be produced from 10.87 g of Ag? Al(NO3)3(aq) + 3 Ag(s) → Al(s) + 3 AgNO3(aq) B. What mass of O2 can be generated by the decomposition of 100.0 g of NaClO3? 2NaClO3(s) → 2 NaCl(s) + 3 O2(g) C. What mass of Fe is generated when 100.0 g of Al are reacted? Fe2O3(s) + 2 Al(s) → 2 Fe(s) + Al2O3(s)

• 18.55 A steady current was passed through molten CoSO4 until 2.35 g of metallic cobalt was pro- duced. Calculate the number of coulombs of elec- tricity used. • 18.59 The passage of a current of 0.750 A for 25.0 min deposited 0.369 g of copper from a CuSO4 solution. From this information, calculate the molar mass of copper. 18.87 In a certain electrolysis experiment involving Al+ ions, 60.2 g of Al is recovered when a current of 0.352 A...
