Question

Because of their reactivity, we do not find most representative metals as free elements where?

Answer 1

in nature

[PCl 3][Cl 2]  0.135  0.135  = = 0.021 0.87 [PCl 5] The equilibrium constant calculated from the equilibrium concentrations is equal to the value of Kc given in the problem  when rounded to the proper number of significant figures . Thus, the calculated equilibrium concentrations check. Kc =.
