Na₂CO₃(s) → 2Na⁺(aq) + CO₃²⁻(aq)
The sodium carbonate formed from a strong base and a weak acid. Hydrolysis is subjected to the anion of a weak acid.
CO₃²⁻ + H₂O ⇄ HCO₃⁻ + OH⁻
HCO₃⁻ + H₂O ⇄ H₂CO₃ + OH⁻
pH>7 alkaline solution
2Na⁺ + CO₃²⁻ + 2H₂O ⇄ 2Na⁺ + 2OH⁻ + H₂CO₃
Answer:
Explanation:
Each magnesium atom loses two electrons and each iodine atom gains one electron. So there should be a 1-to-2 ratio of magnesium ions to iodide ions.
That’s B I’m good at chem
Answer:
Tetrahedral
Bent
Explanation:
A molecule in sp3 hybridization is ordinarily expected to exhibit tetrahedral electron domain geometry. This implies that it has four electron domains.
We were specifically informed in the question that two lone pairs are present. Remember that lone pairs distort the molecular geometry away from the expected geometry based on VSEPR theory.
Therefore, the bond angle of the molecule is <<109.5 degrees and its molecular geometry is bent (e.g water)
