At stp, 1 l of br2 reacts with 3 l of f2 to completion and produces 2l of a product. what is the formula of the product

The formula of the product   when Br2  reacts with 3L  of F2 to   completion and produce 2 L of the product is

       2 BrF3
Br2  +3F2 = 2BrF3

1 mole  of  Br  reacted  3 moles of f2 to form 2  moles of BrF3

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).
