what would be the effect on your calculated mass percent recovery of Cu if you did not completely react the Mg in the reaction mixture? Briefly explain.
Cerium is often used as a reducing agent. Although it is expensive, it has a high stabile and constant value of E^ o over a PH range from 0 to 7.
Eventually, his mother decides to take him to the doctor who diagnoses it as an acute case of middle ear infection (otitis media), and prescribes amoxicillin for his treatment. He weighs 44lb, and the daily dose of amoxicillin for the treatment of..
If you were to perform this reaction in a lab, you would make far less than the theoretical yield of product due to a wide range of outside factors. We can compare the actual yield to the theoretical yield to calculate the percent yield:
What is the final pH of a solution that contains 0.1 M of H2N-CH2-CH2-NH3+ Cl- and 0.01 M of Cl- NH3+-CH2-CH2-NH3+. The pKa values of the compound are as follows; pKa1= 7.5 and pKa2= 9.5:
suppose you want to find out how many milliliters of 1.0 M AgNO3 are needed to provide 169.9g of pure AgNO3.
In the near future, the college will attempt to reduce the cost of chemicals used in campus laboratories. One option suggests the chemistry department use household chemicals instead of expensive laboratory grade materials were ever possible.
