The activity of the antibiotic penicillin slowly decomposes when stored in a buffer at pH 7.0, 298K. The time dependence of the penicillin antibiotic activity
Indicate the pH at (a) the beginning of the titration (0.0 mL titrant) and after the addition of (b) 12.5 mL, (c) 24.0 mL, (d) 24.9 mL, (e) 25.0 mL, (f) 25.1 mL, and (g) 30.0 mL of the titrant. Label the half-neutralization point and the equivalen
You are interested in determining the rate of reaction with respect to I in the reaction of KI and Na2S2O3 to form I2and K2S2O8. What reagent volume(s) would you vary in time trials to get this information?
List the following in decreasing order of strength (from strongest to weakest): hypochlorous acid, choric acid, perchloric acid, chlorous acid. Explain what trend in these oxoacids is making them progressively more acidic.
Mixtures of helium and oxygen are used in scuba diving tanks to help prevent "the bends". For a particular dive, 18.9 L of oxygen gas at 25.0oC and 1.25 atm, and 7.58 L of helium gas at 25.0oC and 1.13 atm were pumped into a tank with a volume of
Calculate the correct volume of sulfuric acid which will need to be added to neurallize the base. The chemical reaction involves Al(OH)3 and Fe2O3 reacting with KOH and H2SO4 with the end product being KAL(SO4)2*12H2O.
What is the reaction between four carbons with the triple bond on the third and fourth ones and HCl? Then what reaction is that product and HBr
An acetylene tank for oxyacelylene welding will provide 9340 liters of acetylene gas, C2H2, at STP. How many tanks of oxygen, each providing 7.00 X 10 to the 3rd liters of O2 at STP, will be required to burn the acetylene, forming CO2 and H2O?
What is the new pressure, in atm, when the air is placed in tanks that have the following volumes, if there is no change in temperature and amount of gas?
