Explain HOW this chemical reaction is NOT balanced correctly. SiF4 + 2 H2O --> H4SiO4 + 2 H2SiF6

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).

"electrical energy" transforms to "thermal energy".hope my answer has you : )

They cool it down and aluminum cools easily
