As a debate kid, the purpose of the source is to provide evidence on a point. You are proving that your point matters by giving a piece of evidence that supports what you’re trying to say. Without evidence your claim isn’t impactful.
Ba²⁺(aq) + CO₃²⁻(aq) → BaCO₃(s)
Answer:
Explanation: Electrolysis uses DC electricity as a energy source.
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
