Calculate the standard cell potential, Ecell, for the equation Cr(s) + F2(g)—>
Cr2+(aq) + 2F-(aq)
Use the table of standard reduction potentials.

The answer is !

Ibelieve y y even though i've only taken chemistry for one year

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).
