Areaction of 1 liter of chlorine gas (cl2) with 3 liters of fluorine gas (f2) yields 2 liters of a gaseous product. all gas volumes are at the same temperature and pressure. what is the formula of the gaseous product? (type your answer using the format co2 for co2.)

When gasses are under the same conditions (same temperature and pressure),  the volume relationships between gasses, give the coefficients of the balanced equation. 

So,  

Now, we can find the product using this balanced chemical equation.

On reactant side, we have :


Product will contain 2Cl + 6F  atoms 


= 2(Product)

So, The formula of the product is =
