question 27

Multiple Choice

What is the net ionic equation for the single replacement reaction Ca(s) + 2 HNO₃(aq) → H₂(g) + Ca(NO₃) ₂(aq) Calcium is above hydrogen in the activity series.

• A)Ca(s) + NO₃^-(aq) → CaNO₃^-(aq)
• B)2 H⁺(aq) → H₂(g)
• C)Ca(s) + 2 H⁺(aq) + 2 NO₃^-(aq) → Ca²⁺(aq) + H₂(g) + N₂O(g)
• D)Ca(s) + 2 H⁺(aq) → Ca²⁺(aq) + H₂(g)
• E)Ca(s) + 2 H⁺(aq) + 2 NO₃^-(aq) → H₂(g) + Ca²⁺(aq) + 2 NO₃^-(aq)
