Morning to whoever is reading this! For reference, I'm doing college chemistry 1301, A Carbonate Analysis: Molar Volume of Carbon Dioxide. I'm trying to find the vapor pressure of H2O at 21 degrees C. Other information includes: Barometric pressure is 756 torr. Volume of volume in CO2 collecting cylinder is 50 ml, with the final being 21 ml. If you can't find the answer based on these results, then you can kindly explain how to find Vapor Pressure, I'll work on it.
Consider the reaction with the rate law, Rate = k[BrO3-][Br-][H+]2 By what factor does the rate change if the concentration of BrO3- is tripled and that of Br- is tripled
Hydrosulfuric acid is a diprotic acid for which Ka1 = 5.7 X10-8 and Ka2 = 1X10-19. Find out the concentration of sulfide ion in a 0.10 M hydrosulfuric solution.
A solution of a specific vitamin has ?max = 273 nm and a concentration of 6.51 × 10-7 M. The absorbance of the solution at 273 nm is A = 0.180. What is the molar absorptivity of the vitamin at 273 nm? (sample pathlength = 1.00 cm)
