Which reactant is limiting?

Show work

Explanation:

1. Balanced chemcial equation:

2. Theoretical mole ratio

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

3. Actual ratio

It is ratio of the moles available to reat:

4. Comparison

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:

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
