Write a scientific argument that addresses the question: Which suspect is most likely to have made the hydrofluoric acid? First,
state your claim. Then, use evidence to support your claim. For each piece of evidence you use, explain how the evidence supports your claim. As you write, refer back to your completed Modeling Tool sheets and Science Seminar Evidence Cards.
We need 2 reasons why its either Pat or Tracy. I need a paragraph on it.

Answer : The moles of left in the products are 0.16 moles.
Explanation :
First we have to calculate the moles of .
Using ideal gas equation:
where,
P = pressure of gas = 1 atm
V = volume of gas = 10 L
T = temperature of gas =
n = number of moles of gas = ?
R = gas constant = 0.0821 L.atm/mol.K
Now put all the given values in the ideal gas equation, we get:
Now we have to calculate the moles of .
The balanced chemical reaction will be:
From the balanced reaction we conclude that,
As, 1 mole of react with 2 moles of
So, 0.406 mole of react with
moles of
Now we have to calculate the excess moles of .
is 20 % excess. That means,
Excess moles of =
× Required moles of
Excess moles of = 1.2 × Required moles of
Excess moles of = 1.2 × 0.812 = 0.97 mole
Now we have to calculate the moles of left in the products.
Moles of left in the products = Excess moles of
- Required moles of
Moles of left in the products = 0.97 - 0.812 = 0.16 mole
Therefore, the moles of left in the products are 0.16 moles.
