a.) Calculate the volume of carbon dioxide gas at stp, produced when 651g of ammonia carbonate (NH4)2CO3 decomposes to produce ammonia gas (NH3) carbon dioxide and water vapor. b.) Calculate the total volume of all gases produced under those conditions.
The gas-phase reaction Cl(g)+HBr(g) => HCl(g)+Br(g) has an overall enthalpy change of -66kJ. The activation energy for the reaction is 7kJ. What is the activation energy for the reverse reaction?
The Henry's Law constant for carbon dioxide gas in water at 25 oC is 0.031 mol/L-atm. Calculate the solubility of carbon dioxide in water at 25 oC in moles/L if the partial pressure of carbon dioxide in the headspace above a water sample is 1.68 a..
C2H4 Flows into a catalytic reactor at 25atm and 300 degrees C with a flow rate of 1010 L/min. Hydrogen at 25atm and 300 degrees C with a flow rate of 1050L/min. If 11.0kg of C2H6 are collected per minute, what's the percent yield of the reaction?
The mixture is diluted with deionized water to the mark and shaken vigorously. What mass of AgBr would precipitate from this mixture?
The difference between the energy of the photons and the kinetic energy of the electrons corresponds to the energy needed to remove the electrons (that is, the ionization energy). Suppose that a PES experiment is performed in which mercury vapor i..
A 4.5 g sample of LiCl at 25 degrees Celsius dissolves in 25 mL of water also at 25 degrees Celcius. The final equilibrium temperature of the resulting solution is 60.8 degrees celsius. What is the enthalpy of solution delta H subscript 8 of LiCl ..
