In a gaseous 2L reaction system, 2.00 mol of methane, CH4(g) is added to 10.00 mol of chlorine, Cl2(g). At equilibrium, the system contains 1.40 mol of chloromethane, CH3Cl(g), as well as some hydrogen chlorine, HCI(g).
a) State a balanced chemical equation for this equilibrium.
b) Compute the amount of each substance at equilibrium.
Polychlorinated biphenyls (PCBs), which were formerly used in the manufacture of electrical transformers, are environmental and health hazards. They break down very slowly in the environment. The decomposition of PCBs can be represented by the equ..

A sample of an unknown gas effuses in 11.9 min. An equal volume of H2 in the same apparatus at the same temperature and pressure effuses in 2.19 min. What is the molar mass of the unknown gas
If 3.20mL of vinegar needs 41.5mL of 0.150 molarity NaOH to reach the equivalence point in a titration, how many grams of acetic acid are in a 1.50qt sample of this vinegar?
What volume of 1 M HCl do you have to add to change the pH of the solution to 6? Assume that the change in volume from adding HCl is negligible. Recall that pH = pKa + log([A-]/[HA]. I cannot, for the life of me, figure this out.
