<span>Ba2+(aq)+2I−(aq)+2Na+(aq)+SO2−4(aq)→BaSO4(s)+2I−(aq)+2Na+(aq)
The spectator ions are: </span><span>Na</span>⁺, I⁻.
They appear on both sides of the reaction, hence did not take part in the reaction.
Answer:
<h2>2.44 L</h2>
Explanation:
The volume can be used by using the formula for Boyle's law which is

where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we're finding the final volume

We have

We have the final answer as
<h3>2.44 L</h3>
Hope this helps you
