Question

13. 1 mol of monoatomic ideal gas at 300 K expands
from 1 L to 8 L in two different process
Process I: Reversible adiabatic expansion
Process II : Irreversible adiabatic expansion against
the constant external pressure of 1 atm (given 1
atm L = 101 J)
Select the correct statement.
(1) IW process il = Wprocess
W ul
(2) IT fl Process = IT process II (f → final)
(3) IT il process > IT fl Process II (f → final)
(4) Change in internal energy in process Il is less
than change in internal energy of process
(Only magnitude)​

Answer 1

Answer:  it is negative ion option C

Explanation:  It must lose two electrons and become an ion. ... What best describes the bromide ion that forms? It is a negative ion that has one more valence electron than a neutral bromine atom. All atoms of the element potassium have 19 protons.
