Benzene as well as toluene mix to form a liquid solution @20degrees C and solution behaves as ideal solution. Explain the Vapor pressure of pure benzene is 74.7Torr and that for pure toluene is 23.3Torr. Explain the mole fraction of each in the VAPOR phase if there are 3.12moles of benzene as well as 1.25 moles of toluene
The Haber process is an important reaction for the fixation of nitrogen, nitrogen is converted into ammonia, an important component in the production fertilizers. N2(g) + 3H2 = 2NH3(g) + 22,000cal
Synthesis gas can be made by reacting red-hot coal with steam. Estimate the temperature at which the equilibrium constant for the reaction is equal to 1.

Which element has an oxidation number of 7. A. Mn in MnO4- B. I in IO3- C. Fe in Fe2O3 D. Cl in ClO2
Draw the structure of a compound with the following analytical data: a mw of 72 g/mol, no silver mirror in a Tollen's test, and a yellow precipiate formed in an iodoform test.
the outside of the flask is dried before its mass is measured. 1) Will the mass of the vapor in the flask be too high too low, or unaffected. 2) Will the molar mass of vapor in the flask be reported too high, too low, or unaffected.
Life is dependent on four major classes of biomolecules. What are they. Why are they important
Nitric oxides, NO and NO_2, contribute to air pollution, acid rain, and the depletion of the ozone layer. After NO forms in the combustion chamber of an automobile engine, it reacts further with oxygen to form NO_2. The reaction is given by 2NO (g..
The standard change in gibbs free energy= -69.0 kJ/mol. What is the change in G for this reaction at 298K when the partial pressures are PNO=0.100 P02=0.350 PN02=0.700 atm
Magnesium metal rects with oxygen to make a white powder knon as magnesium oxide. As the reaction proceeds, a bright white flame is seen. It is found that 2.6 g of magnesium reacts with1.6 of oxygen.
