Suppose a 250. mL fask is filled with 0.40mol of O2 and 0.20mol of SO3. This reaction becomes possible: 2SO2(g)+O2(g)2SO3(g) Complete the table below, so that it lists the initial molarity of each compound, the change in molarity of each compound due to the reaction, and the equilibrium molanty of esch compound after the reaction has come to equilibrium. Use x to stand for the unknown change in the molanty of O2. You can leave out the M symbol for molarity
