(a)
Interpretation:
To estimate the mass of lime required to precipitate magneisum from sea water.
Concept introduction:
Magnesium is an alkaline earth metal and is prsent in sea water. The magnesium present in sea water can be extracted by precipitating it with either
(b)
Interpretation:
To estimate the mass of product produced at anode and cathode on electrolysis of
Concept introduction:
Magnesium is an alkaline earth metal and is prsent in sea water. The magnesium present in sea water can be extracted by precipitating it with either
The reduction happens at cathode
The oxidation happens at anode.
The total number of Faradays of electricity used is calculated by the number of electrons involved in the reaction
(c)
Interpretation:
To estimate how many Joules are required per mole for the given industrial process

Draw the enolate ion in its carbanion form. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. ⚫ Separate multiple reactants using the + sign from the drop-down menu. ? 4arrow_forwardShown below is the mechanism presented for the formation of biasplatin in reference 1 from the Background and Experiment document. The amounts used of each reactant are shown. Either draw or describe a better alternative to this mechanism. (Note that the first step represents two steps combined and the proton loss is not even shown; fixing these is not the desired improvement.) (Hints: The first step is correct, the second step is not; and the amount of the anhydride is in large excess to serve a purpose.)arrow_forwardHi I need help on the question provided in the image.arrow_forward
