Question- In the photochemical decomposition of a certain cmpd, light intensity of 5.4 x 10^-6 einsteins s^-1 was employed. Assuming the most favorable conditions, estimate the time needed to decompose 1 mole of the compound.
Show all work, use additional paper if necessary.
How would you prepare 250mL of a buffer having a pH of 3.60 using 0.500M NaOH and 0.500M of HNO2. Would you calculate the molarities of the conjugate acid and base pair and then somehow get the volumes from that
the only difference between succinate and fumarate is the geometry around their double bonds, one contains a cis double bond,
The sample is diluted with 73.454 g of water. A 10.315 g aliquot of this solution is then titrated with 0.1079 M HCl. It required 29.41 mL of the HCl solution to reach the methyl red endpoint. Calculate the weight percent NH3 in the aqueous waste.
