Two students beging by mixing 5.0ml of a 3.1M solution of methyl orange and 5.0 ml of a 3.1 M solution of methyl red in an Erlenmyrer flask. How many drops of this mixture must be added to the top of the column so that 6.0 mmol of each dye is separated. 21drops = 1ml

Consider the following reaction:

CO(g)+2H2(g)⇌CH3OH(g)CO(g)+2H2(g)⇌CH3OH(g)

The reaction between COCO and H2H2 is carried out at a specific temperature with initial concentrations of COCO = 0.26  M M and H2H2 = 0.49  M M. At equilibrium, the concentration of CH3OHCH3OH is 0.16  M M.

Part A

Find the equilibrium constant at this temperature.

Express your answer using two significant figures.

Balance the following redox equations either in acid or base:
