1.49 moles of Al will be produced. Hope this helps you.
The correct answer is realistic and reliable
Hi!
When titrating Calcium and Water solution, if there is some CaCO3 in the solution, the following reactions may occur in acid solution:
CaCO₃ + H⁺ → Ca⁺² + HCO₃⁻
HCO₃⁻ + H⁺ ↔ H₂CO₃ → CO₂ (g) + H₂O
The bubbles are from CO₂ that is being developed from an acidic solution of CaCO₃
Answer:
H+(aq) + OH-(aq) → H2O(l)
Explanation:
Step 1: Data given
aqueous sodium hydroxide = NaOH(aq)
aqueous hydrochloric acid =HCl(aq)
Step 2: The (un)balanced equation
HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)
For 1 mol HCl we need 1 mol NaOH to produce 1 mol NaCl and 1 mol H2O
This equation is already balanced.
Step 3: The net ionic equation
H+(aq) + Cl-(aq) + Na+(aq) + OH-(aq) → Na+(aq) + Cl-(aq) + H2O(l)
The net ionic equation, for which spectator ions are omitted - remember that spectator ions are those ions located on both sides of the equation - will , after canceling those spectator ions in both side, look like this:
H+(aq) + OH-(aq) → H2O(l) (The last option is correct)
