The Thermite reaction is used to weld railway lines. It is a combustion reaction and creates a flame. Is it an endothermic or exothermic reaction?

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).
