Study the model. The model shows a sodium chloride compound. What kind of substance is shown here?

Sorry i dont understand the question can you rephase it?

While unproven, it uses facts to support part of a conclusion. it is still factual and has predictive power, however.

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).
