Answer to Question #246365 in General Chemistry for Dranxs

Question

The galvanizing f iron sheet can be carried electrolytically using a bath containing zinc sulfate solution. The sheet is made the cathode, and a graphite anode is used. Calculate the cost of electricity required to deposit 0.49 layer of zinc on both sides of an iron sheet 2.0 m wide and 80m long if the current is 30 A, the voltage is 3.5 V, and the energy efficiency of the process is 90%. Assume the cost of electricity is Php 12.50 per kilowatt-hr. The density of zinc is 7.1g/cm'.

Answer 1

V= 35×10×10²×10⁴

35×10⁷

7.1× 0.49×30

= 104.37

35×10⁷/104.7

= Php 334288
