M = moles of solute / liters of solution
2.00 M = x / 10.0 L
x = 20.0 mol
Suppose the molarity was listed as 2.0 M (two sig figs). How to display the answer? Like this:
20. mol
Molecules starts to get farther apart from each other. At boiling point the state of water changes to gas.
Explanation: energy levels are three(counting number of cyecles) outer electrons are 3 also
Answer:3,3
Answer:
Energy is absorbed, and an emission line is produced.
Explanation:
Electrons are present and revolving continuously in the orbits that are present around the nucleus. The energy of electron are fixed and unable to move to other orbits due to the strong attractive force of the proton which is present in the nucleus of the atom. If the electron wants to jump from the first energy level to the second energy level, so the electron has to absorb enough energy which can overcome the attractive force of proton.
