The volume of 350. mL of gas at 25°C is decreased to 250, mL at constant pressure. What is the final temperature of the gas? A)-60.1 C B) 213 C

Explanation / Answer

Ans 23 : C) The valence electron configuration is identical to carbon

The valence electron configuration of the element mentioned here is 4s2 4p4 , and that of carbon is 2s2 2s2.

These both configurations do not match at all.
