Suppose you are given 0.0856ppm to be the concentration of dissolved lead found in pond water after dilution factor of 1:100 in 100ml volumetric flask and the other sample is diluted at the dilution factor of 1:2 and the concentration is 2.14ppm. How would you comment on the amount of lead in pond water
A student measured 20 drops of vinegar and one drop of phenolphthalein solution into a well of her well plate. After she had added 35 drops of NaOH solution to the same well, the well was full, but she had still not reached the titration endpoint. She then took a clean pipet and transferred some of the titration mixture into a second well. She rinsed the pipet with a few drops of distilled water and transferred the rinse water into the titration mixture in the second well. Then she continued adding NaOH solution to both wells until she reached the endpoint in both wells. She then recorded the total number of drops of NaOH solution added to both wells and used it to calculate the data for her vinegar titration. Briefly comment on her procedure and the accuracy of her results.

Adenosine triphosphate, ATP, is used to store energy within biological systems. It releases that energy by losing a terminal phosphate group, Pi, to form adenosine diphosphate, ADP, through the hydrolysis reaction ATP(aq) + H2O(I) → ADP(aq) + Pi(aq) + H+(aq) . The standard reaction Gibbs energy, ΔrGΘ, for the hydrolysis of ATP to ADP is+ 10 kJ mol-1 at 298 K.This assumes that the concentration of hydrogen ions is 1 mol dm-3 .
