Calculate the [Zn2+] in a solution of ZnC2O4 held at a pH of 3.00. Remember C2O4^2- is a weak base so you must consider other equilibria. (Ksp(ZnC2O4)=7.5X10^-9, Kb1=1.8X10^-10, Kb2=1.8X10^-13). Solve using systematic treatment of equilibrium.
A local bank offers a customer a 2-year car loan of $10,000 as follows: Money to pay for car : $10,000 Two years' interest at 7% : 2 x 0.07 x 10,000 : $1400 (11,400 total) 24 monthly payments : 11400 / 24 = $475.00
