Hello! Let me try to answer this :)
Thanks and please correct if there are any mistakes ^ ^
Answer:
B: The sulfuric acid is not consumed or react with the reactant.
Answer: The final pressure is 34.48kPa
Initial Pressure P1 = 55.16kPa
Initial Volume V1 = 0.500L
Final Pressure P2 = ?
Final Volume V2 = 0.800L
Boyle's law P1V1 = P2 V2
P2 = P1V1/V2
P2 = 55.16*0.5/0.8
P2 = 34.48kPa
Answer: None of the above
Explanation: It is not possible for any of these animals to undergo metamorphosis.
