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


Read this paragraph and choose the correct option from the provided answers:

[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 =.

 Choices:

- in water

- in the atomospher

- underground

- in nature


A:
in nature
