I think the best answer from the choices listed above is option C. With this accident, both should be alert and do what should be done. Lee should tell the teacher while Celia washes her arm with soap and water. Doing this, Celia will prevent the chemical to spread more and harm further. Telling the teacher immediately will also alert the in-charge and do what should be done.

Answer:

3 mol Cl₂/2 mol AlCl₃ (three over two)

Step-by-step explanation:

Start with the balanced equation"

2Al + 3Cl₂⟶ 2AlCl₃

The steps in the calculation are

mass of AlCl₃ ⟶ moles of AlCl₃⟶ moles of Cl₂ ⟶ mass of Cl₂

The critical step is the conversion of moles.

You multiply the moles of AlCl₃ by a conversion factor to get moles of Al:

Moles of AlCl₃ × conversion factor = moles of Al.

The conversion factor is the molar ratio, and it uses the coefficients of the formulas in the balanced equation.

It is either (2 mol AlCl₃/3 mol Cl₂) or (3 mol Cl₂/2 mol AlCl₃).

You choose the one that has the desired units of the answer in the numerator.

We choose the second option, because it has the correct units.

For example,

$\text{0.2 mol AlCl}_{3} \times \frac{3\textbf{ mol Cl}_{2} }{ 2\text{ mol AlCl}_{3} } = 0.3\textbf{ mol Cl}_{2})$

Notice how the units "mol AlCl₃" cancel and the correct units appear in the answer.

If we had used the other conversion factor, we would have gotten the wrong units.
