A mixture of gases contains 4.46mol of neon, 0.74mol of argon, and 2.15mol of xenon. Calculate the partial pressures of the gases if the total pressure is 2.00atm at a given temperature.
How much heat is released when 4.50 g of methane gas is burned in a constant-pressure system? CH4 (g) + 2O2(g) -> CO2 (g) + 2H2O(l) H=-890kJ
What osmotic pressure would develop across the membrane if the temperature is 26.0 degrees Celcius?
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.
if a raindrop weighs 65 mg on average and 5.1x10^5 raindrops fall on a lawn every minute what mass in kg of rain falls in 1.5 hours
