2. An electrolytic cell is set up for the production of aluminum, which involves the reduction of Al3+ to AL The external source passes a current of 11.2 A through the cell with an emf of 6.0 V. How long does it
take for the cell to produce a pound (454 g) of aluminum metal?
(a) 220 h
(6) 40 lir
10) 121h
(d) 3.26 10 h

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

diaria maybe go see a doctor about that
