Answer:
The theoretical yield of the hydrogen sulfide is 68.0 grams.
Explanation:
Moles of aluminum sulfide = 4.0 mol
Moles of water = 4.0 mol
According to reaction, 6 moles of water reacts with 1 mole of aluminum sulfide,then 4 moles of water will react with :
of aluminum sulfide
1.5 moles aluminum sulfide < 4 moles aluminum sulfide
This means that water is present in limiting amount and aluminum sulfide is in excess amount.So, amount of hydrogen sulfide will depend upon moles of water.
According to reaction, 6 moles of water gives with 3 mole of hydrogen sulfide,then 4 moles of water will give :
of hydrogen sulfide
Mass of hydrogen sulfide:
2.0 mol × 34 g/mol = 68.0 g
The theoretical yield of the hydrogen sulfide is 68.0 grams.
The answer is donating. This is because when an atom loses electron, it <em>donates</em> them to another atom.
D. propane and hydrogen gass
We see in the given name of the hydrocarbon that the root word is pentane from 2,2,4-trimethylpentane. Pentane is a hydrocarbon chain that contains 5 carbon atoms. Therefore, the answer to this item is 5 carbons.
Answer:
2) HClO3 is stronger because chlorine is more electronegative than iodine.
Explanation:
The more electronegative the element is the more strong or acidic it becomes.
Chlorine being more electronegative than Iodine makes it easier for it to pull the electron of hydrogen more strongly and hence has a higher tendency to release a H+ unit. Hence that makes it stronger.
