how many grams of F2 are needed to react with 3.50 grams of Cl2 Equation needed for question- Cl2+3F2-->2ClF3 please explain how to get the answer.

5.62 g of F2

Explanation:

We have to start with the chemical reaction:

We have a balanced reaction, so we can continue with the mol calculation. For this, we need to know the molar mass of  (70.906 g/mol), so:

Now, with the molar ratio between  and  we can convert from moles of  and  (1:3), so:

Finally, with the molar mass of we can calculate the gram of (37.99 g/mol), so:

I hope it helps!

the correct answer is:

a. formation of precipitation

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
