if 2.29 moles of argon gas are added to 3.5L of a 6.58 mole sample of argon gas what is the final volume
Compute the volume of CO 2 and water vapour produced and the volume of oxygen remaining, when 20.0 dm 3 of propane reacts with 120.0 dm 3 of oxygen. All gas volumes are measured at the same temperature and pressure.
The heat of vaporization of water =40.66 kJ/mol at 100 °C. Compute the quantity of heat that is absorbed/released when 9.00 grams of steam condenses to liquid water at the temperature of100 degree celsius.
A tightly sealed 5.0 L flask contains argon at 69.0 deg. C and 781 mm Hg. The flask is heated until the pressure is doubled. What it the temperature of the gas.
An alcohol is 12.61 percent Hydrogen, 37.47 percent Carbon, and 49.92 percent Oxygen by mass. Determine the empirical formula of the alcohol.
A sample of helium gas has a volume of 241 mL at 0.83 atm. What pressure is needed to reduce the volume at constant temperature to 35 mL.
