You have a liquid-phase mixture of 0.250 mol fraction ethanol and 0.750 mol fraction water at 760.0 mmHg. You\'d like to calculate the bubble-point temperature of the mixture, and the composition of the vapor formed at the bubble-point temperature two different ways. For the first method, assume that the solution behaves ideally and all components follow Raoult\'s law.
1.What is the bubble-point temperature of the solution?
2. What are the mole fractions of ethanol (e) and water (w) in the vapor phase at the bubble-point temperature?
In the chemical reaction used in automotive air-bag safety systems, N2(g) is produced by the decompositon of sodium azide, NaN3, at a somewhat elevated temperature:

How many gm of dry NH4Cl need to be combined to 2.30L of a 0.300M solution of NH3, to prepare a buffer solution of pH 8.85.
Show the Chemical behavior of an atom - The chemical behavior of an atom is determined by most directly by the
Draw out partial pathways to show which carbon(s) of glucose are lost in the first two cycles of the TCA cycle after entry as acetyl CoA fragments.
the resulting mixture has (pb2+)i=1.0x10^-3M, (so4^-2)i=1.0x10^-4 for pbso4 ksp=1.3x10^-8. compare qsp to ksp and decide whether a precipitate will form.
Hydrazine derivatives are commonly used in rocket fuels. Combustion of N2H4 produces N2(g) and H2O(g). When 1.00 g of N2H4 is burned in a bomb, DT = 3.51 oC. If C = 5.51 kJoC-1, what is the quantity of heat evolved? What is DH of this reaction?
The variation of the atmospheric pressure p with altitude h is predicted by the barometric formula to be p = p0 e^(-h/H) where p0 is the pressure at sea level and H=RT/Mg with M the average molar mass of air and T the average temperature. Obtain t..
