16.3L of nitrogen gas, N2 at 25.0 degrees Celsius and 125kPa and 32.2L of oxygen gas, O2 at 25.0 degrees Celsius and 125kPa were transferred to a tank with a volume of 4.75L. What is the total pressure of the mixture at 31.0 degrees Celsius?
how many liters of carbon dioxide are produced at 100 kPa and 22 degrees celsius if 75.0 L of methane react? CH4 + 2 O2 —> CO2 + 2 H2O
A glass flask has a volume of 500 ml at a temperature of 20 degrees celsius. The flask contains 492 ml of mercury at an equilibrium temperature of 20 degrees celsius. The temperature is raised until the mercury reaches the 500 ml reference mark. The coefficients of volume expansion of mercury and glass are 18*10^-5 K^-1 and 2.0*10^-5 K^-1, respectively. The temperature at which this occurs, in degrees celsius is closest to:
A sample of O2 gas weighs 52.0 grams. If the gas is at 25 degrees celsius and a pressure of 2.33 atm, what is a volume of the gas in liters?
A 1m3 air tank is initially at 100 kPa and 17 degrees Celsius. It is to be filled by a compressor that delivers air at 700 kPa and 52 degrees Celsius. When the tank is filled it is allowed to reach thermal equilibrium and the tank is at 17 degrees Celsius and 600 kPa. Determine the amount and direction of heat transfer between the tank and surroundings. (Hint: first find the initial mass of air in the tank, the final...
Determine the stoichiometry of the 02 uptake by calculating the ratio moles Co(salen):moles O2 From the volume change at the measured temperature and pressure, calculate the ratio of the number of moles of Co(salen) to the number of moles of 02 absorbed, which, ideally, could be either 1:1 or 2: The initial volume is 4.8 mL, the final volume is 2.70 mL, the temperature is 17.5 degrees Celsius and the barometerie pressure is 936 bar, we used 0.06 mg of...
