Question

Predict whether the following double-replacement reaction will produce a precipitate: Ca(C2H3O2)2 + Na2CO3 --> CaCO3 + 2 NaC2H3O2

No; all products are soluble
Yes; the CaCO3 will precipitate
Yes; the NaC2H3O2 will precipitate
Yes; both the CaCO3 and NaC2H3O2 will precipitate

Answer 1

I know CaCO3 will form a precipitate because all carbonates do that. so your answer is B
