Initially, the reaction vessel contained 0.20 M iron(III) ions and 0.20 M SCN-(aq). Once equilibrium was reached, the FeSCN2+(aq) had a concentration of 0.15 M. What is the value of the equilibrium constant, K, for this reaction under these conditions?

18. use the activity series to predict whether the following synthesis reaction will occur. write the chemical equations for the reaction if it's predicted to occur. (s) + o2(g) -> *note: it is possible.*
