Asample of a compound of xenon and fluorine was confined in a bulb with a pressure of 16 torr. hydrogen was added to the bulb until the pressure was 64 torr. passage of an electric spark through the mixture produced xe and hf. after the hf was removed by reaction with solid koh, the final pressure of xenon and unreacted hydrogen in the bulb was 32 torr. what is the empirical formula of the xenon fluoride in the original sample?

•what conclusions can you make about the relationship between the volume of a gas and its temperature? • what conclusions can you make about the relationship between the volume of a gas and its pressure? • what possible variables have you not accounted for? as you did the procedures, is it possible that the atmospheric pressure may have changed? if it did change over the course of your experiment, then how would your results have been affected?
