5.80 mol of solid a was placed in a sealed 1.00-l container and allowed to decompose into gaseous b and c. the concentration of b steadily increased until it reached 1.20 m, where it remained constant.
a(s) equilibrium b(g) +c(g)
then, the container volume was doubled and equilibrium was re-established. how many moles of a remain?
hint: start by finding the value of k. make a table that expresses the initial and final amounts of each species. we can use moles in the table so long as we convert back to concentrations before plugging into the k expression. fill in the missing values in this table, then calculate kc. hint: you can use the stoichiometry of the reaction to determine the changes in a and c.

Listen base your answer to the question on the information below. propane is a fuel that is sold in rigid, pressurized cylinders. most of the propane in a cylinder is liquid, with gas in the space above the liquid level. when propane is released from the cylinder, the propane leaves the cylinder as a gas. propane gas is used as a fuel by mixing it with oxygen in the air and igniting the mixture, as represented by the balanced equation below. c3h8(g) + 5o2(g) → 3co2(g) + 4h2o() + 2219.2 kja small amount of methanethiol, which has a distinct odor, is added to the propane to consumers detect a propane leak. in methanethiol, the odor is caused by the thiol functional group (–sh). methanethiol, ch3sh, has a structure that is very similar to the structure of methanol. what is the correct structural formula for a molecule of methanethiol
