Answer:
No limiting reagent. There is an exact amount of each.
Explanation:
Start by getting the equation
Fe + O2 -> Fe2O3
If you balance the oxygens the Fe will easily follow.
Fe + 3O2 => 2Fe2O3
So far what you have is 6 oxygens on the right and 6 on the left. Now all you need do is balance the irons. The are 4 on the right (2Fe2). So you must have 4 on the left.
4Fe + 3O2 -> 2Fe2O3
Now to your question if you have 4 mols of iron, you need 3 mols of O2. Those are the balance numbers of the equation. They also represent mols.
There is no limiting reagent in the theoretical world of chemistry. All the iron will be used up and so will the given amount of oxygen.

Answer:
The root mean squared velocity for CF2Cl2 is 
Explanation:
From the question we are told that
The temperature is 
Root Mean Square velocity is mathematically represented as

Where T is the temperature
MW is the molecular weight of gas
R is the gas constant with a value of 
For CF2Cl2 its molecular weight is 0.121 kg/mol
Substituting values
