You carry out a titration of a pure weak triprotic acid and only see two major pH jumps. One at 10.0 mL and one at 15.0 mL. At what volume is the other equivalence point?
1) How many litres of hydrogen gas will be produced by the decomposition of 90 L of water? (Assume that temperature and pressure are constant) Show ALL work.
Suppose the volume of this system is compressed to one-half its initial volume and then equilibrium is reestablished. what would be the new equilibrium total pressure.
Reaction of an Alcohol to Produce an Alkyl Halide, N-butanol reacts with NaBr and H2SO4 to produce n-butyl bromide, via refluxation reaction in a lab experiment.
From this information and the atomic mass, calculate the edge length of the unit cell. Now assume that rubidium atoms are spheres. Each corner sphere of the unit cell touches the body centered sphere. Calculate the radius of a rubidium atom.
A sample of gas with a volume of 750 mL exerts a pressure of 98 kPa at 30 ?C.What pressure will the sample exert when it is compressed to 250 mL and cooled to -25 ?C?
