Phosphorus pentachloride decomposes to phosphorus trichloride at high temperatures according to the equation: PCl5(g) ? PCl3(g) + Cl2(g) At 250° 0.375 M PCl5 is added to the flask. If Kc = 1.80, what are the equilibrium concentrations of each gas?
A gas is confined to a container with a massless piston at the top.A massless wire is attached to the piston. When an external pressure of 2.00 rm atm is applied to the wire, the gas compresses from 5.90 to 2.95 L. When the external pressure is in..
Write the equations that represent the first and second ionization steps for selenic acid (H2SEO4) in water.
A compound A(C6H6) undergoes catalytic hydrogenation over lindlar catalyst to give a compound B, which in turn undergoes ozonolysis followed by workup with aqueous H2O2 to yield succinic acid and two equivalents of formic acid.
