Simple chem problem, please help

If a certain battery supplies 1.0×108 electrons per second to the negative terminal and the battery contains 7.00 moles of electrolytic solution (which means the solution contains 7.00 moles of hso4), what fraction of the solution undergoes a chemical reaction each second

Give the set of reactants (including an alkyl halide and a nucleophile) that could be used to synthesize the following ether: draw the molecules on the canvas by choosing buttons from the tools (for bonds and charges), atoms, and templates toolbars, including charges where needed. ch3ch2och2ch2chch3 | ch3

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)
