How many kj of heat are needed to completely vaporize 3.30 moles of h2o?

1 answer:

8 0

Water requires 40.65 kJ of heat per mole to vaporize it completely

Multiply this by the number of moles you have

40.65 kJ x 3.3 moles = 134.145 kJ

ANTONII [103]

Answer:- $1s^22s^22p^4$ .

Explanation:- Atomic number for fluorine(F) is 9 and it's electron configuration is $1s^22s^22p^5$ . $F^+$ is formed when F loses one electron from it's valence shell.

$F\rightarrow F^++1e^-$

Second shell is the valence shell for fluorine and so it loses one electron from 2p to form $F^+$ and the electron configuration of the ion becomes $1s^22s^22p^4$ .
