Answer: The squirrel's balloon will be 0.86 L
Explanation:
To calculate the new volume, we use the equation given by Boyle's law. This law states that pressure is directly proportional to the volume of the gas at constant temperature.
The equation given by this law is:

where,
are initial pressure and volume.
are final pressure and volume.
We are given:

Putting values in above equation, we get:

Thus the squirrel's balloon will be 0.86 L
D is the correct answer... if u need in depth let me know
Carbonic acid is produced when a strong acid reacts with the bicarbonate buffer system in the human body.
The concentration of NaOH is 25.00% by mass, it means that 25.00% of the mass of the solution is of NaOH. Hence:
