Best ResponseYou've already chosen the best response.2Im thinking [x]/[.25][.25]=3.0x10^3 which becomes x=.003x.0625=.00019 which is equivalent to 1.9x10^4M being the concentration of Fe3+. If you are wondering why there is only one x in the numerator it is because the Ag is a solid and therefore falls out of the equation.

Best ResponseYou've already chosen the best response.0Use Kc= (concentration of product1^mol * concetration of product2^mol)/(concentration of reactant1^mol * concentration of reactant 2^mol) Also, take note that Kc works for Aqueous substances only.

Best ResponseYou've already chosen the best response.0Making substitutions, we get 3*10^3= (Fe3+)^1/(0.25^1 * 0.25^1) Fe3+= 0.625* (3*10^3)= 1.875*10^3 or A.
