At 5 oC the equilibrium constant for the reaction: 2 HBr(g) H2(g) + Br2(g) is KP = 2.80e-16. If the initial pressure of HBr is 0.00991 atm, what are the equilibrium partial pressures of HBr, H2, and Br2? p(HBr) = . p(H2) = . p(Br2) =
Consider the titration of 30.0 mL of 0.048 M NH3 with 0.025 M HCl. Calculate the ph after the following volumes of titrant have been added.
the vapor of a volatile liquid is able to fill a 408-mL flask at 100.4C and 765mm Hg, what is the molar mass of the liquid?
Draw the missing intermediate and add curved arrows for the production of phenylethyne by the double dehydrohalogenation
Suppose that the reaction X+Y==> Z has a rate law=k[X][Y] a.What is the overall order of the reaction? b.What is the order with respect to X?To Y?
Given there is an increase in volume, which increases possible microstates, how can there be no increase in entropy?
An old synthetic procedure starts by calling for fifteen kilo grams of sulfuric acid. If your largest reaction vessel holds ten litres, can you put the fifteen kilograms of acid into the vessel, or would you require to scale down the reaction reag..
A pure fluid is described by the following expression for Gibbs free energy: G = gamma(T) + RTlnP, where gamma(T) is a substance specific function of temperature.
HPLC analysis of basic analytes is better to perform at low pH when they are fully ionized (2 pH units lower than analyte pKa). For the analyte with pka= 5.6 and 60/40 acetonitrile/water eluent composition what should be the pH of an aqueous porti..
Methanol is toxic for humans if they ingest liquid methanol or inhale methanol vapor in significant quantities. When inhaled in concentration greater than 1000 ppm, death has been reported.
The iron content of hemoglobin can be determined by converting the iron to Fe2+ and titrating using MnO4 -. A 5.0 g sample of hemoglobin requires 21.6 mL of 0.00310 M potassium permanganate. What is the percent of iron in the hemoglobin sample?
Fluoride (F-) is toxic element (anion) that can be lethal at 0.20 g/70kg of body weight. But because F- at low levels (1ppm) aids in healthy teeth, municipal water sources normally add this level of fluoride.
