The correct answer is 2.53 g of precipitate, BaCrO4.
Hyperventilation<span> will blow off carbon dioxide which reduces the alkaline component of the </span>blood<span>, resulting in acidosis and a lower </span>blood pH<span>. (See Andromeda Strain). This is why re-breathing into a bag to increase carbon dioxide in your </span>blood will make you feel less faint. Basically <span>It increases the pH ... you can look at CO2 as an acid ... and when reduced ... alkalinization of the pH occurs</span>
Answer:

Explanation:
Hello there!
In this case, since we have a problem about volume-pressure relationship, the idea here is to use the Boyle's law to calculate the final volume as shown below:

Then, we plug in the initial and final pressures and the initial volume to obtain:
