An Orsat analysis of the combustion of a strange unearthly hydrocarbon gas produces a (dry) result of 5.00% each for CO2, CO, and O2, with N2 making up the remainder. Determine
a. The hydrocarbon fuel model CnHm for this strange and somewhat putrid gas.
b. The mass composition of this gas.
c. The percent of excess air used in the combustion.
Define they hydrogen atom is not actually electronegative enough to form bonds to xenon. Explain were the xenon-hydrogen bond to exist, Define what would be the structure of XeH4
In the left compartment there is nitrogen at 1.0 atm and 25°C; in the right compartment there is oxygen at the same temperature and pressure. Calculate the entropy and Gibbs energy of mixing when the partition is removed. Assume that the gases are..
