The equilibrium constant, Kc, for the following reaction is 10.5 at 350 K. 2CH2Cl2(g) CH4(g) + CCl4(g)

Calculate the equilibrium concentrations of reactant and products when 0.277 moles of CH2Cl2 are introduced into a 1.00 L vessel at 350 K

answer; ///i do believe that the correct answer is (b); ///particle composed of two or more atoms bonded together;

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
