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:
It is a strong acid.
Explanation:
A strong acid is any acid that is completely ionized in solutions to release the greatest number of hydronium ions or protons when placed in a solution.
So, when 99.9% of a substance dissociates to release hydronium ions. It is considered as a strong acid.
Answer:
Yes
Explanation:
AsH3 contains a polar bond.
I think the best answer that will describe chemical change is the first option. During a chemical change, b<span>oth the identity and the properties of a substance change because new substances are being formed by a chemical reaction. An example is rusting of steel</span>
Sea salt and rock salt, rock salt is gathered from salt deposits found underground, sea salt is obviously from the sea :/
Hope this helps you
