Answer:

Explanation:
Hello,
In this case, the molecular chemical reaction is written as:

In such a way, considering the net ionic notation and the solid yielded copper (I) bromide, we write:

Whereas ammonium and sulfate ions are spectator ions, therefore the net ionic equation is:

Regards.
Ans: Final volume = 25.0 ml
<u>Given:</u>
Initial volume V1 = 50.0 ml
Initial pressure P1 = 20.0 atm
Final pressure P2 = 40.0 atm
<u>To determine:</u>
The final volume V2
<u>Explanation:</u>
Ideal gas equation: PV = nRT
under constant temperature, T and number of moles n we have:
PV = constant
or, P1V1 = P2V2
V2 = P1V1/P2 = 20*50/40 = 25 ml.
