What is the cell potential for the reaction Mg(s)+Fe2+(aq) -> Mg2+(aq)+Fe(s) at 63 degrees celsius when [Fe2+] = 3.50M and [Mg2+] = 0.310M. Express your answer to three significant figures and include the appropriate units.
calculate the value for E for the cell at 25oC (b) A current is drawn from the cell until 1.20 g of silver have been deposited at the silver electrode. Calculate the value of E for the cell at that stage of operation.
the calorimeter itself absorbs a negligible amount of heat, calculate combustion eneergies (change of energies) for benzene in both kj/g and kj/mol.
Compound A has the molecular formula C14H25Br and was obtained by reaction of sodium acetylide with 1,12-dibromododecane. On treatment of compound A with sodium amide, it was converted to compound B (C14H24).
