Answer:
Explanation:
The chemical reaction of the well-balanced equation is as follows:

The aforementioned reaction's ionic equation is:

From above; Na⁺ and Cl⁻ appear on both sides;
Hence, the net ionic equation is:

Answer:
The gases will expand until a volume of Vf= 10812 cm^3
Explanation:
Since the gas mixture is expanding at constant pressure

and therefore

knowing that 1 torr=133,32 Pa

therefore
