Argon is a noble gas that boils at -186°C. Consider the compounds HCl, F2, NaF, and HF. Which compound would you predict to have the boiling point closest to argon? Why?

m=9

step-by-step explanation:

7m+8=71 subtract   8 from 71 which is 63 than divide it by 7m   equal 9.

                             

Yeah, but what are you trying to ask?

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).

The correct answer is:   [a]:   the "stratosphere" .
