The electrons rearrange themselves to ensure that orbitals at lower energy levels are first filled before those at higher energy levels.
<h3>Electronic configuration</h3>One of the rules of electronic configuration states that lower energy level orbitals are first filled with electrons before higher energy level orbitals.
Thus, the electrons in Gold will rearrange themselves to obey the above rule in order to achieve more stability.
Hence, the electronic configuration becomes:

Answer:
(A.) CO2, H2O
Explanation:
The chemical equation for respiration process is:
+
→
+
+ ATP↑
Energy is released during the biochemical process in the organism's cells in form of ATP. Byproducts of the reaction are carbon dioxide and water molecules.

Answer:
Mass of H₂O is 3.0g
Explanation:
The reaction equation is given as:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
Parameters that are known:
Mass of CO₂ used = 7.3g
Unknown: mass of water consumed = ?
Solution
To solve this kind of problem, we simply apply some mole concept relationships.
Number of moles of CO₂ =
6 moles of CO₂ reacted with 6 moles of H₂O(1:1)
Workings
>>>> Number of moles of CO₂ =?
Molar mass of CO₂ :
Atomic mass of C = 12g
Atomic mass of O = 16g
Molar mass of CO₂ = 12 + (2 x16) = 44gmol⁻¹
Number of moles of CO₂ = = 0.166moles
>>>>>> if 6 moles of CO₂ reacted with 6 moles of H₂O, then 0.166moles of CO₂ would produce 0.166moles of H₂O
>>>>>> Mass of water consumed = number of mole of H₂O x molar mass
Mass of H₂0 = 0.166 x ?
Molar mass of H₂O:
Atomic mass of H = 1g
Atomic mass of O = 16
Molar mass of H₂O = (2x1) + 16 = 18gmol⁻¹
Mass of H₂O = 0.166 x 18 = 3.0g
