The combustion of a mysterious unknown hydrocarbon fuel in the dimensional stabilization module of the temporal drive unit produces the following Orsat (dry) exhaust gas analysis: 4.50% CO2, 1.90% CO, 14.1% O2, and 79.5% N2: Determine
a. The fuel model (CnHm) and its probable name.
b. The percent mass composition of the fuel.
c. The percent of theoretical air used in the combustion.
d. The dew point temperature of the exhaust products at 1.00 MPa.
The titration of 25.0 mL of 0.00 M base (B) by 0.500 M HCl for which the following data was collected. Volume of HCl added (mL) pH
what volume of ethylene glycol, a nonelectrolyte, must be added to 15.0 Liters of water to produce an antifreeze solution with a freezing point of - 30 degrees celcius? what is the boiling point of the solution?
How much PV work is done (in kilojoules), if 90.0 g of ethylene and 125 g of HCl are allowed to react at atmospheric pressure and the volume change is -71.9 L?
A solution is made by mixing 46.0 mL of ethanol, C2H6O, and 54.0 mL of water. Assuming ideal behavior, what is the vapor pressure of the solution at 20 °C
Three Liters of gas at STP is mixed with another 3 liters of gas at STP. The volume is then reduced to 1 liter at standard temperature. What is the pressure?
Problem- A 2.135 sample of gaseous chlorofluorocarbon occupies a volume of 315.5 mL at 739.2 mm Hg and 26.1 degrees C. Analysis of the compound shows it to be 14.05% C, 41.48% Cl, and 44.46% F by mass. Find the empirical formula and then the molec..
a previously evacuated tank with a capacity of .1m3 is pressurized with 1kg each of heliummolar mass 4.0 and

Given that the present flux of anthropogenic Na+ into the oceans is 3.39 x 1012 mol yr-1, how long would it take to increase the concentration of Na+
An experiment requires 40.0 of ethylene glycol, a liquid whose density is 1.114 . Rather than weigh the sample on a balance, a chemist chooses to dispense the liquid using a graduated cylinder. What volume of the liquid should he use?
Draw a Lewis structure that obeys the octet rule for each of the following anions. (Assign lone pairs, radical electrons, and atomic charges where appropriate.)
