The main difference between the 3 isotopes of hydrogen are the number of neutrons in the nucleus. Hydrogen has no neutrons, Deuterium has one neutron, and tritium has two neutrons. All three have one proton and one electron.
The correct mole ratio of K₃PO₃ and KNO₂ in the chemical reaction is 1 : 3
<h3>Balanced equation</h3>
3Mg(NO₂)₂ (aq) + 2K₃PO₃ (aq) -> Mg₃(PO₃)₂(aq) + 6KNO₂(aq)
from the balance equation,
- The number of mole of K₃PO₃ = 2 moles
- The number of mole of KNO₂ = 6 moles
<h3>How to determine the mole ratio of K₃PO₃ and KNO₂</h3>
- Number of mole of K₃PO₃ = 2 moles
- Number of mole of KNO₂ = 6 moles
- Mole ratio of K₃PO₃ and KNO₂ =?
Mole ratio = mole of K₃PO₃ / mole of KNO₂
Mole ratio of K₃PO₃ and KNO₂ = 2 / 6
Mole ratio of K₃PO₃ and KNO₂ = 1 : 3
