1. For Part 1, describe the changes in the colors of the well, if any, as you go from well 1 to well 9—that is, as you go from the well with the least copper(II) nitrate to the well with the most copper(II) nitrate. Which wells had the most distinct precipitate? For Part 2, describe […]
A 2.20−g sample of water is injected into an evacuated 2.00−l flask at 45.0°c. what percentage of water will be vapor when the system reaches equilibrium? assume ideal behavior of water vapor and that the volume of liquid water is negligible. the vapor pressure of water at 45.0°c is 71.9 mmhg.
Consider the reaction a(g) + b(g) <–> c(g) + d(g). you have the gases a, b, c, and d at equilibrium. upon adding gas a, the value of k:
