At what temperature is the substance a heated gas ?
2 answers:
Answer: Option (c) is the correct answer.
Explanation:
Temperature at below zero degrees represent that the substance is in solid state.
Temperature at zero degree celsius represents that substance starts to melt.
Whereas temperature at 100 degree celsius represents that the substance is changing from liquid to gas.
On the other hand, temperature above 100 degree celsius represents that the liquid has completely converted into gas.
Thus, we can conclude that above temperature is the substance a heated gas.

Answer: 4.5 moles of can be made from complete reaction of 3.0 moles of Al.
Explanation:
The given reaction equation is as follows.
This shows that 2 moles of Al reacts with 6 moles of HCl. So, the amount of HCl required to react with 1 mole Al is three times the amount of HCl.
Therefore, 3 moles of Al will react with 9 moles of HCl to give 3 moles of and
moles of
.
The reaction equation now will be as follows.
The moles can also be written as 4.5 moles.
Thus, we can conclude that 4.5 moles of can be made from complete reaction of 3.0 moles of Al.
