Molecular chlorine and molecular fluorine combine to form a gaseous product. under the same conditions of temperature and pressure it is found that one volume of cl_2 reacts with three volumes of f_2 to yield two volumes of the product. what is the formula of the product?

Explanation:

According to the law of conservation of mass, a chemical reaction can only be balanced when the number reactants equal the number of products.  

The reaction between molecular chlorine and fluorine is given as follows.

where,     x = subscript of chlorine

               y = subscript of fluorine

Number of atoms on reactant side are as follows.

Number of atoms on product side are as follows.

Therefore, to balance the given chemical equation, place the value of x as 1 and value of y as 3 on the product side.

Hence, the balanced chemical equation is as follows.

the answer would be c. motion and direction

i hope this : )
