For the first ionization energy for an N2 molecule, what molecular orbital is the electron removed from
olga55 [171]

Answer:

p orbital.

Explanation:

Valence electrons are the electrons in an atom holding the very last orbital which is used in chemical bonding with other elements. Their existence could define the chemical properties of that atom.

During the first energy in ionization of an N2 molecule the molecular orbital from which the electron could be extracted is the only one with the highest energy level. Nitrogen has its outermost orbital (p) containing three valence electrons. Each orbital is only half filled, and thus it is unstable Thus, the electron mission must have been removed from p orbital.

If you have a 1234 gram sample of C4H7NO4, how many gams of Carbon would<br><br> be present?
Tpy6a [65]

Answer: 445.4 grams of carbon would be present.

Explanation:

According to avogadro's law, 1 mole of every substance contains avogadro's number 6.023\times 10^{23} of particles and weighs equal to its molecular mass.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{1234g}{133g/mol}=9.28moles

As 1 mole of C_4H_7NO_4 gives = 4 moles of carbon

Thus 9.28 moles of C_4H_7NO_4 gives = \frac{4}{1}\times 9.28=37.1 moles of carbon

Mass of carbon = moles\times {\text {Molar mass}}=37.1moles\times 12g/mol=445.4g

Thus there are 445.4 grams of carbon would be present.
