Identify the spectator ion(s) in the equation: 2Ag+(aq) + 2NO3–(aq) + 2Na+(aq) + S2–(aq) --> Ag2S(s) + 2Na+(aq) + 2NO3–(aq)
2Ag+(aq) + 2NO3–(aq)
2Na+(aq) + 2NO3–
2Na+(aq) + S2–(aq)
Ag2S(s) + 2Na+(aq
What is the net ionic equation for the precipitation reaction between BaCl2 and Na2SO4?
BaCl2(aq) + Na2SO4(aq) --> BaSO4(s) + 2NaCl(aq)
Na+(aq) + Cl-(aq) --> NaCl(s)
Ba2+(aq) + SO42-(aq) --> BaSO4(s)
Ba2+(aq) + 2Cl-(aq) + 2 Na+(aq) + SO42-(aq) --> BaSO4(s) + 2Cl-(aq) + 2Na+(aq)
