Suppose that the mercury in a barometer were replaced by a liquid metal alloy with a density of 4.36 g/cm^3. The density of mercury is 13.6 g/cm^3. What height of a column of liquid alloy would be supported by 1.00 atm pressure?
A mixture of O2, CO2, and N2 has a total pressure of 762. torr. In this mixture the partial pressure of O2 is 112. torr and the partial pressure of CO2 is 185. torr. What is the partial pressure of the N2 (in torr)?
Calculate the initial concentrations of [SCN-] IONS and Fe3+ ions when a solution was prepared by mixing 3.00 more of 0.00280 M KSCN, 6.00 more of 0.250 M Fe(NO3)3 and 16.00 more of 0.050 M HNO3
a lake with constant volume 10 x 106 m3 is fed by a pollution-free stream with flow rate 50 m3s. a factory dumps 5 m3s
Which is the best estimate of the pH of a solution that has a hydroxide ion concentration of 1.25 x 10^ -5M? Excess oxygen gas reacts with 244 g of iron to produce 332 g of Fe2O3. What is the percent field?
Explain what the percentage of calcium is in an ionic compound of unknown composition if a 2.241g Sample of the compound is completely dissolved in water and produces 1.252g of CaCO3 upon addition of an excess of Na2CO3 solution.
3.00 moles of an ideal gas at 27 degrees Celsius expands isothermally from an initial volume of 20.0dm3 to a final volume of 60.0dm3. Compute w for this process (a) for expansion against a constant external pressure of 1.00 x 105 Pa and (b) for a ..
Compare the relative rate of the foward (EtOH as a substrate) and back reaction (with acetylaldehyde). Use the Michaelis-Menten equation to solve for v when ethanol is 99mM and acetylaldehyde is the substrate and its concentration is 1mM
