For the following reaction at equilibrium, indicate if the equilibrium mixture contains mostly products, mostly reactants, or both products and reactants.
2H20(g)-><-2H2(g)+O2(g) kc+4x10-48
2H20(g)-><-2H2(g)+O2(g) kc+4x10-48

Technically, everything reacts a little so we always have some products and some reactants. However, from a practical stand point, look at the K and how you write the expression.
Kc = (H2)^2(O2)/(H2O)^2
Kc = 4E-48. That's a VERRRRRRY small number. That means the numbers on top are small and the numbers on the bottom are large. That's the only way you can get a very small number. What does that tell you about the relations?

It tells us that there isn't much product but a lot of reactant. It is mostly reactants.
