Consider the following reaction:

CO(g)+2H2(g)⇌CH3OH(g)

A reaction mixture in a 5.23-L flask at a certain temperature initially contains 26.5 g CO and 2.35 g H2. At equilibrium, the flask contains 8.64 g CH3OH.

Calculate the equilibrium constant (Kc) for the reaction at this temperature.

Embryos of different species look very similar, which shows that the organisms share a ancestor.
