What is the molar form of the ideal gas law?</h3>
The ideal gas law is a straightforward formula that describes the relationship between an ideal gas's pressure P, volume V, and temperature T. Unless there is a strong reason to treat gases differently, we normally treat gases as ideal because of how straightforward this relationship is:-
PV=nRT
where ;
P= Pressure=?
V= Volume= 10.5 L
n= no.of mol.= 82.5 mol
R=Ideal gas constant= 8.314 joule / mol kelvin
T=Temperature= 317 K
using Given value:-
P= nRT/ V
P=(82.5 x 8.314 x 317) / 10.5
P=20707.7 atm

The element X is Copper.
Explanation :
Reactive metals from 3d transition series like Cu are very reactive because their standard reduction potential values are low.
Hence, when treated with a acid it tends to liberate hydrogen gas.
Also, because of its low reduction potential value, it can easily displace lead and tin from their salt solutions.

Answer:
If a metal is less reactive than carbon, it can be extracted from its oxide by heating with carbon. The carbon displaces the metal from the compound, and removes the oxygen from the oxide. This leaves the metal.
