Find the number of moles of gas in a 70L container assuming that the pressure of gas is 50mm Hg and that the temperature is 350degC
Methane is completely burned with 20.0% excess air, with 25.0% of the carbon going to CO. What is the partial pressure of CO in the stack (exit) gas if the gas exits at a pressure of 740 mm Hg and a temperature of 300°F
Calculate the volumetric size of a water molecule in vapor, assuming 1 mole of the vapor occupies 22.4 L, as if the vapor were an ideal gas
what is the percent yield of water produced when 138 g ethyl alcohol c2h5oh is combusted in excess oxygen if the actual
This chamber is equipped with enough solid KOH to absorb any CO2 and H2O produced by the mouse. The gas volume in this chamber is measured to be exactly 2.20 L, at the temperature is held constant at 297 K. After two hours the pressure inside the ..
It is important to know if a particular molecule is composed of elements with different electronegativities as well as the structure of the particular molecule to explain the physical properties of the molecule.
Standard reduction potentials for the Pb2+/Pb and Cd2+/Cd haf-reactinos are -.13V and -.40C, respectively. At what relative concentrations of Pb2+ and Cd2+ will these half-reactions have the same reduction potential?
Explain how the Law of Combining Volumes, combined with the atomic-molecular theory, leads directly to Avogadro's hypothesis that equal volumes of gas at equal temperatures and pressure contain equal numbers of particles.
What would happen to the A450 value for a smaple which include : 1mL of 0.0025M Fe(NO3)3 + 1mL of 0.0025M KSCN + 5.0mL of 0.1M HNO3 , if you accidentally added 5 drops of disodium hydrogen phosphate
