HELP: In this lab, it is not necessary to calibrate the volume of a drop from a Beral pipet, so long as you use the same Beral pipet for all titrations and you handle it consistently. A solution that contains 3.0 x 10^-5 mol of oxalic acid requires 24 drops of permanganate ion solution to reach the endpoint of the titration. What is the chemical amount of permanganate ion per drop?
Illustrate the structure for 2-bromo-3-methyl-3-heptanol. Depict the molecule by placing atoms on the grid as well as connecting them with bonds.
Problem- A reservoir containing retrograde gas has a reservoir pressure higher than the dew-point pressure of the gras as evidenced by constant producing gas-oil ratio. The gas is produced through three stages of seperation. Surface production rat..
