A reaction vessel contains 2.50 moles of ci2 and 6.15 moles of f2 how many moles of excess reactant are left

2.4moles

Explanation:

Number of moles of Cl₂  = 2.50moles

Number of moles of F₂  = 6.15moles

Unknown:

Moles of excess reactant left = ?

Solution:

The reaction equation:

              Cl₂  +  3F₂   →  2ClF₃

Now, we need to find the excess reactant;

       2 mole of chlorine gas combined with 3 mole of fluorine gas;

      2.5 moles of chlorine gas will combine with  = 3.75moles of F₂

The given number of moles of F₂ is 6.15moles

But the reaction needs 3.75 moles

The amount of excess reactant left  = 6.15 - 3.75 = 2.4moles

the answer is: they rebelled against saddam hussein’s rule.

kurds opposed saddam rule and wanted independence. kurds in the north and shiites in the south revolt against hussein.

for example, the halabja attack in 1988 conducted against the kurdish people by the iraqi regime under saddam hussein, where between 4000 people are killed and around 9000 are injured.
