For each of the following ground state electron configurations, determine what is incorrect. N: 1s²2s¹2p³ A) The configuration is not in the ground state. B) The configuration is missing an electron in the 2s orbital. C) The configuration has too many electrons in the 2p orbital.

B

Explanation:

It should be 2s² which means the answer is the configuration is missing an electron in the 2s orbital.

B.

Explanation:

It should be 2s² which means the answer

is the configuration is missing an electron

in the 2s orbital.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
