A sample of neon gas is contained in a rigid container at 100K and 1 atm. what is one change that would make the gas act more like an ideal gas

Higher temperature and lower pressure

Explanation:

Generally, a gas behaves more like an ideal gas at higher temperature and lower pressure, as the potential energy due to inter molecular forces becomes less significant compared with the particles' kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.

3 1/4 %

explanation:

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
