When the reaction 2 H2S g ~ 2H2 + S2 is carried out at 1065 degrees celcius, Kp = 0.012. Starting with pure H2S at 1065degrees, what must the initial pressure of H2S be if the equilbrated mixture at this temperature is to contain 0.250 atm of H2 (g)?
Calculate the mass of ethylene glycol (C2H6O2) that must be added to 1.00 kg of ethanol (C2H5OH) to reduce its vapor pressure by 11.9 torr at 35°C. The vapor pressure of pure ethanol at 35°C is 1.00 multiplied by 102 torr
Sometimes during a reaction contamination can be introduced into the sample. If this happens which of the following would be true about the mass of the sample if it were contaminated
Calcium fluoride, CaF2, is a source of fluorine and is used to fluoridate drinking water. Calculate its molar mass to four significant figures.
Use standard enthalpies of formation to determine Horxn for: 3NO2(g) + H2O(l) ? 2HNO3(aq) + NO(g) Enter in kJ. -133.5 Find the change in internal energy for this reaction.
The hydrogen carbonate ion can act as both an acid and a base. Write out two equations which demonstrate this and calculate (or look up) the equilibrium constants for both expressions
Glucose is much more soluble in water than 1-hexanol even though both have 6 carbons. Explain
The higher heating value (HHV) of a fuel is its standard heat of combustion at 25 C with liquid water as a product; the lower heating value (LHV) is for water vapor as product.
