Solution :
Assuming all Al will be consumed in the reaction.
From the given equation, 2 mole of Al produce 2 mole of .
So, 1 mole of Al produce 1 mole of . .....statement 1)
Number of moles of Al in 258 gram of Al.
Therefore, from statement 1) number of moles of produced is also 9.556 moles.
Answer: The final volume decrease with an increase in pressure at constant temperature
Explanation:
According to Boyle's law, pressure of a gas is inversely proportional to the volume of a gas at constant temperature and constant number of moles.
where,
= let initial pressure of gas = p
= final pressure of gas = 2p
= initial volume of gas = v
= final volume of gas = ?
Now put all the given values in the above equation, we get:
Thus the final volume decrease with an increase in pressure at constant temperature
