Answer:
Like a gas, a liquid is able to flow and take the shape of a container.
Answer:
Lithium
Explanation:
The answer is Lithium because the Alkali metals family is in the group 1A and the element neon is in the second period. If you look at the periodic table group 1A and the second period connects at the element Lithium.
Wrong, the electron configuration for antimony using the Nobel gas notation is: [Kr]5s24d105p3
The answer to your questions is as follows:

I hope my answer has come to your help. God bless and have a nice day ahead!
Answer:
96 torr
Explanation:
After 48 hours, we are told, the pressure is 488 torr. Since we started with 392 torr of arsine, we can conclude there is an increase in pressure cause by the arsine producing hydrogen and the solid As.
We can calculate the equilibrium pressure of H₂ if we account for the total pressure in terms of the stoichiometry of the equilibrium equation:
2 AsH₃(g ) ⇆ 2 As(s) + 3 H2(g)
Initial p (atm) 392 0
Change -2x 3x
Equilibrium 392 - 2x 3x
and the total pressure at equilibrium is the sum of the pressure of the gasses arsine and hydrogen:
488 = (392 - 2x)+ 3x
488 - 392 = x
x = 96
Therefore the equilibrium pressure of H₂ is 3 x 96 = 288 torr
