Answer 1

Time to 6.og og erom can be a mass pe= 6.000 1 - 5.44 A f = 96500 como molar mass of irom = 56 g/mol calculate the mechat na moles of ison moles re = 6.0 = 0.107 mol 56 Reduction reaction of iron Pet2 + é re There is a 2:1 ratio between elections Total electron transfer - 2 moles of election - 2x.107 calculate the electricity needed 0 =0xF and iron o = 0.214796500 = 20,651 finally calculate the time 0-18t 20,651 = 5.44 xt

t = 3,796 seconds t = 3796 min 60 " t = 63.26 60 hours. t = 1.05 hours. So. The time needed is 1.05 hours
