Q1) Faraday's equation: Consider two electrochemical reactions. What are the net reaction rates for reaction A and reaction B (in mol of reactant per unit area per time)? a) Reaction A results in the transfer of 2 mol of electrons per mole of reactant and generates a current of 5 A on an electrode of 2 cm² in area. b) Reaction B results in the transfer of 3 mol of electrons per mole of reactant and generates a current of 15 A on an electrode of 5 cm² in area.

Volumetric pipettes are designed to deliver a precise amount of liquid, but only if you a. submerge the end of the pipette into a solution you are delivering. b. allow the pipette to drain freely, and leave any residual solution in the pipette. c. hold the pipette at a 45 degree angle and ensure that all the liquid is delivered.

Only water or dilute aqueous solution or non toxic chemicals may be disposed of down the drain with copious water     true   false
