Which is the correct equilibrium constant expression for the following reaction? Fe2O3(s) + 3H2(g) --> 2Fe(s) + 3H2O(g) Kc = [Fe2O3] [H2]3/[Fe]2[H2O] Kc = [Fe]2[H2O]3/[Fe2O3] [H2]3 Kc = [H2]/[H2O] Kc = [H2O]3/[H2]3 Kc = [Fe] [H2O]/[Fe2O3] [H2]

Plzz a sample of table sugar (sucrose, c12h22o11) has a mass of 7.801 g. ● a) calculate the number of moles of c12h22o11 in the sample b) calculate the number of moles of each element in c12h22o11 (number of moles of c, number of moles of h & number of moles of o) in the sample. (use your answer from part a as your starting point.) show your work and highlight your final answer. calculate the number of atoms of each element in c12h22o11 (number of atoms of c, number of atoms of h & number of atoms of o) in the sample. (use your answers from part b as your starting for each element.) show your work and highlight your final answer.
