The energy of a particle in a box with equal sides (a) can be expressed h2 as: e = 8ma n +n) what is the degeneracy of the 2nd lowest energy level? 2 what is the energy difference (ae) between the 1st and 2"d energy level for an electron in a box with sides 1.0 nm.

"a connection, a bond or common feeling between two people", or as a chemical process it stimulates love or sexual attraction

the answer is a and have a great day

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
