I think you mean ionic bond and not conic bond. The pair of elements that form an ionic bond are barium and chlorine.
Answer: The energy of an electron in the n = 2 level of a hydrogen atom is 3.40 eV.
Explanation:
Given: n = 2
The relation between energy and orbit of an atom is as follows.
Substitute the values into above formula as follows.
The negative sign indicates that energy is being released.
Thus, we can conclude that the energy of an electron in the n = 2 level of a hydrogen atom is 3.40 eV.
Answer:
True
Explanation:
Methylcyclohexane has a cyclic compound of 7 carbons false classified as Saturated Hydrocarbon.
Answer:
3.5 mole of carbon
Explanation:
The atomic mass of carbon is 12.011 grams per mole.
That means, every mole of carbon atoms has a mass of 12.011 grams.
If you have 42.035 grams of carbon atoms, then every 12.011 grams of those carbon atoms, is 1 mole of carbon atoms...
You can solve this using unit conversion:
# mole carbon atoms = 42.035 grams C x (1 mole C / 12.011 g C) = 3.5 mole C
