Barium metal crystallizes in a body centered cubic lattice. the unit cell edge length is 502 pm. calculate the atomic radius of ba.

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).

Ionic compounds dissociate into component ions dissolved into a solution creating substances called "electrolytes".hope my answer has you : )

Ithink it’s carbon dioxide
