A proper chemical storage includes the following;

- Management – this includes of managing the storage area of the chemical and how they are stored base on their difference and property

- Compliance – this is the action needed in means of having to be able to understand the properties of the chemical in order to know what action is needed to engaged on

Which reactant is limiting? Show work

fenix001 [56]

Answer:

1. Iodine is the limiting reactant

2. $6molAlI_3$

Explanation:

1. Balanced chemcial equation:

$2Al+3I_2\rightarrow 2AlI_3$

2. Theoretical mole ratio

It is the ratio of the coefficients of the reactants in the balanced chemical equation:

$\dfrac{2molAl}{3molI_2}$

3. Actual ratio

It is ratio of the moles available to reat:

$\dfrac{9molAl}{9molI_2}$

4. Comparison

$\dfrac{9molAl}{9molI_2}>\dfrac{2molAl}{3molI_2}$

Then, there are more aluminum available than what is needed to react with the 9 moles of iodine, meaning that the aluminum is in excess and the iodine will react completely, being the latter the limiting reactant.

Conclusion: iodine is the limiting reactant.

5. How much aluminum iodide will be produced?

Use the theoretical mole ratio of aluminum iodide to iodide:

$\dfrac{2molAlI_3}{3molI_2}\times 9molI_2=6molAlI_3\leftarrow answer$

Given that Delta. G for the reaction below is –957. 9 kJ, what is Delta. Gf of H2O? 4NH3(g) 5O2(g) Right arrow. 4NO(g) 6H2O(g) D

vesna_86 [32]

ΔG for the formation of H₂O is -228.6 kJ.

<h3>How we calculate Gibb's free energy of the reaction?</h3>

Gibb's free energy of the reaction is calculated as:

ΔG = G for product - G for reactant

Given chemical reaction is:

4NH₃(g) + 5O₂(g) → 4NO(g) + 6H₂O(g)

In the question, given that:

ΔG for the reaction = -957. 9 kJ

ΔGf of NH₃ = -16. 66 kJ/mol

ΔGf of NO = 86. 71 kJ/mol

Equation for ΔG will be written as:

ΔG = (ΔGf of NO + ΔGf of H₂O) - (ΔGf of NH₃+ ΔGf of O₂)

ΔGf of O₂ = 0

-957. 9 = (4×86. 71 + 6×ΔGf of H₂O) - (4×-16. 66 + 5×ΔGf of O₂)

-957. 9 = 346.84 + 6ΔGf of H₂O + 66.64

ΔGf of H₂O = (-957. 9 - 346.84 - 66.64) / 6

ΔGf of H₂O = -228.56 kJ ≅ -228.6 kJ

Hence, option (1) is correct i.e. -228.6 kJ is the ΔGf of H₂O.
