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.
Answer:
1) The new pressure of the gas is 500 kilopascals.
2) The final volume is 1.44 liters.
3) Volume will decrease by approximately 67 %.
4) The Boyle's Laws deals with pressures and volumes.
Explanation:
1) From the Equation of State for Ideal Gases we construct the following relationship:
(1)
Where:
- Initial and final pressure, measured in kPa.
- Initial and final pressure, measured in mililiters.
If we know that ,
and
, then the new pressure of the gas is:
The new pressure of the gas is 500 kilopascals.
2) Let suppose that gas experiments an isothermal process. From the Equation of State for Ideal Gases we construct the following relationship:
(1)
Where:
- Initial and final pressure, measured in kPa.
- Initial and final pressure, measured in mililiters.
If we know that ,
and
then the new volume of the gas is:
The final volume is 1.44 liters.
3) From the Equation of State for Ideal Gases we construct the following relationship:
(1)
Where:
- Initial and final pressure, measured in kPa.
- Initial and final pressure, measured in mililiters.
If we know that , then the volume ratio is:
Volume will decrease by approximately 67 %.
4) The Boyle's Laws deals with pressures and volumes.
