According to the Bohr model of an atom, what happens when an electron moves from the second energy level to the third energy lev

el and then back to the second energy level? Energy is absorbed and then stored in the atom. Energy is released and then absorbed to form an absorption line. Energy is absorbed and then released to form an emission line. Energy is released from the atom, and the outer level is weakened.

<span>Energy is absorbed and then released to form an emission line.

When electrons absorb energy they increase there energy level. This is only temporary and the excited electron then relaxes back down to its original energy level releasing energy.

The energy is released in form of EM radiation of a specific frequency depending on the element and how many energy levels the electron relaxes. 
This forms an emission line.</span><span />

The energy diagram shows the changes in energy during a chemical reaction.
Brums [2.3K]

There is no diagram attached but there are some ways by which you can find it too easily by yourself

Usually energy diagram uses ∆H .

So

  • If ∆H is +ve means reaction is exothermic and energy is released
  • If ∆H is -ve means reaction is endothermic and energy is absorbed

So observe∆H whether it. is decreasing or increasing ,

  • If increasing then energy is being released and vice versa

How many grams of sucrose (C12H22O11) would be in 8.7 L of a 6.81M solution of sucrose
VladimirAG [237]
<h3><u>Answer;</u></h3>

= 20,280.25 g or 20.28 Kg

<h3><u>Explanation;</u></h3>

Number of moles, n = Molarity × Volume

Molarity = 6.81 M

Volume = 8.7 L

Number of moles = 6.81 × 8.7

                             = 59.247 moles

Mass = Moles × Molar mass

         = 59.247 ×  34.2 g/mol

          = 20,280.25 or

          = 20.28 Kg
