A titration of sulfates in a 5.00 mL sample of drinking water with 10.0 mM (millimolar) of barium acetate as the titrant is carried out. A microflow pump was used instead of a buret, set at a flow rate of 0.122 mL/min. The equilibrium point is reached at 120 seconds. After 200 seconds has passed, what is the concentration of sulfates in the drinking water sample.
The infrared spectrum of the xanthene reduction product contains evidence that demonstrates that conjugation of the rings is still maintained
Calculate k, Calculate also how long it would take for half of A to react. assume pseudo first order with k'=k[OH-], since [OH-] is in great excess.
Calculate the theoretical yield of C2H5Cl when 138 g of C2H6 reacts with 218 g of Cl2, assuming that C2H6 and Cl2 react only to form C2H5CL and HCl.
