To begin with, we need to convert from amps to coulombs: 60 minutes * 60s/min * 15 C/s = 54000 coulombs. Next, we can use this value of charge to convert to moles of electrons: 54000 coulombs * 1 mol e-/96485C = 0.559 mol e-. Then, we can use stoichiometry to convert from mol e- to moles of chromium.AP@ Summer Institute Exam Materials 2007 AP Chemistry These materials' are for training purposes and are intended for use only at an AP Summer Institute.

el mercadito asheboro nc Image From Mister Chemistry. Finally, we divide 1.5mmol H+ by the volume (35mL) to find [H+] = 4.8 * 10^-2, which corresponds to a pH of 1.37. It is worth noting that with strong acid strong base reactions (and other reactions we will discuss), that there are three "zones": the zone where the acid is in excess, where the base is in excess, or where the two are equimolar. weather belton sc 29627calculate gi bill bah AP® Chemistry 2010 Scoring Guidelines .
