For this you will need the latent heat capacity for the vaporization of water.
An element bonds chemically to fill it's outer valence electron shell, when that occurs it becomes stable.

1) By looking at the balanced equation, you can see that 1 mol of Al2S3 needs 6 moles of H2O to fully react . So to react 32 moles, you need 6x32moles of water.
moles H2O needed = 192 moles H2O
However, you don't have 192 moles, you only have 32- This means the water is the limiting
reagent.

So, to fully react 32 moles of water you only need 1/6 of </span><span>Al2S3
</span>
moles <span>of Al2S3
needed= 32* 1/6 =5,33 mol
2)
</span>For the <span>theoretical yield to be maximum amount of product possible we need the limiting reagent to
fully react.
So how many moles of H2S we obtain, from the 32 moles of H2O available to react?
6 moles H2O react to produce 3 moles H2S
moles H2S = 32 x (3 mol H2S / 6 mol H2O)
= 16 mol H2S
the theoretical yield of H2S = 16 mol </span>
Answer:
I believe its C.

"Location" can fit in with distance and location depending on the circumstance.

Answer:
check which reactant is totally consumed and which one remains in the mixture
Explanation:
<em>Apart from doing calculations during an experiment, one can determine which reactant is limiting and which one is in excess by checking the resulting mixture for the presence of reactants.</em>
A limiting reactant is one that determines the amount of product formed during a reaction. It is usually a reactant that is lower than stoichiometry amount.
On the other hand, an excess reactant is one that is present in more than the stoichiometrically required amount during a reaction.
Limiting reactants will be totally consumed in a reaction while excess reactant would still be seen present in mixture after the reaction has stopped.
<u>Hence, apart from using stoichiometric calculation to determine which reactant is limiting or in excess during an experiment, one can just check the final mixture of the reaction for the presence of any of the reactants. The reactant that is detected is the excess reactant while the one without traces in the final mixture is the limiting reactant.</u>
