The equilibrium constant for the following reaction is 0.48 at 25ºC. N2O4(g) -> 2NO2(g)a) Which direction does the equilibrium normally favour? Explain. b) Which compound has the greater concentration once equilibrium is reached? Explain.

Scientists often have to deal with numbers that are either very large or very small. for example, the radius of the sun is approximately 696,000 kilometers, while bacterial cells are as small as 1.9 × 10-4 millimeters. express each number in an alternate form.
