2 answers:
Answer : The correct option is, (B)
Explanation :
Balanced chemical reaction : It is defined as the number of atoms of individual elements present on reactant side must be equal to the product side.
The balanced chemical reaction will be,
By the stoichiometry, we can say that 2 moles of react with 1 mole of
to give 1 moles of
and 1 mole of
.
In this reaction, and
are the reactants and
and
are the products.
Hence, the correct option is, (B)

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.
