Convert the initial rate from units of abs/s to [o-NPG]/s. Use a cell path length, l=1cm and molar extinction coefficient of e=3550 M^-1 cm^-1. Remember that A=ecl where c is concentration.
If needed [o-NPG]=3.84*10^-4 (M)
Average initial rate= .0250 (Abs/s)
Explain the general idea of the LCAO-MO method.
During a standarization of sodium hydroxide solution, it takes 12.35mL of 0.100 M HCl(aq) to neutralize a 25.00 mL sample of the NaOH(aq) solution. What is the concentration of the NaOH(aq) solution?
Arranging the atomic cores appropriately, write the Lewis structure for SiO2 in the box. Use electron pairs to show the bonds between the atoms. Distribute the remaining electrons so that each atom has an octet.
An unknown consisting of a single sugar gives a negative fermentation test. Which one of the following tests would allow you to decide which of the five sugars used in this experiment you had?
