The answer is:
B.electromagnetic energy to chemical energy
Electromagnetic u.v rays from the sun act on chemical substances in the plant chloroplasts producing chemical energy stored and used by the plant.
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.
This is right
Reduce the concentration of NICO4
