Question

Na₂SO₄(aq) + CaCl₂(aq) -> CaSO₄ (s) + 2NaCl(aq)

Now that we have a balanced chemical equation, let's write the ionic equation:

[?] + [?] -> [?] + [?]

A. Na₂SO₄ (aq)
B. 2Na₊(aq) + SO₂₋(aq)
C. Na₊(aq)+SO₂/₄₋(aq)
D. Na₂SO₄(s)

Please help! I have no clue about anything chemistry!!!

Answer 1

Na₂SO₄(aq) + CaCl₂(aq) -> CaSO₄ (s) + 2NaCl(aq)
If it's aq you know it will ionize (as I show it below) and if s(solid) it is shown as is.

2Na^+(aq) + SO4^2-(aq) + Ca^2+(aq) + 2Cl^-(aq) ==> CaSO4(s) + 2Na^+(aq) + 2Cl^-(aq)
