Question
Molecular, ionic and net ionic equations. Is this correct? UNKNOWN IDENTITY AND EQUATIONS UNKNOWN NUMBER:A1S UNKNOWN CATION IDENTITY S Write molecular, ionic, and net-ionic equations for the reaction of YOUR UN KNOWN (it has nitrate as the anion) with each of the eight anion test solutions. If no reaction occurs, complete the molecular and ionic equations, but write "No Reaction" in place of the net-ionic equation. Underline all solids, Include the physical state (s). (aq), etc.) for all species. ionic: net-ionic:NO Renctin ionic: net-ionic: ho rochinm ionic: oneRachian net-ionic: NO 3 (aq) ionic: net-ionic: 2 f 2- Na.soSrExplanation / Answer
2NaCl(aq) + Sr(NO3)2(aq) ------> SrCl2(aq) + 2NaNO3(aq)
No reaction (because no solid/liquid/gas)
Your answer is correct but please check the balanced equation
NaNO3: this is the correct chemical formula
----------------------------------------------------------------------------
2NaBr(aq) + Sr(NO3)2(aq) ------> SrBr2(aq) + 2NaNO3(aq)
No reaction (because no solid/liquid/gas)
Your answer is correct but please check the balanced equation
-----------------------------------------------------------------------------------
2NaI(aq) + Sr(NO3)2(aq) ------> SrI2(aq) + 2NaNO3(aq)
No reaction (because no solid/liquid/gas)
Your answer is correct but please check the balanced equation
----------------------------------------------------------------------------
Na2CO3(aq) + Sr(NO3)2(aq) ------> SrCO3(s) + 2NaNO3(aq)
According to solubility rules
All carbonates are insoluble except Na+, NH4+ and K+
Ionic equation:
2Na+(aq) + CO32-(aq) + Sr2+(aq) + 2NO3-(aq) ------> SrCO3(s) + 2Na+ + 2NO3-(aq)
(Except solid SrCO3, all aqueous compounds are made into ions)
Net-ionic equation:
CO32-(aq) + Sr2+(aq) ------> SrCO3(s)
(Removed all spectator ions)
-----------------------------------------------------------------------------------
Na2SO4(aq) + Sr(NO3)2(aq) ------> SrSO4(s) + 2NaNO3(aq)
Ionic equation:
2Na+(aq) + SO42-(aq) + Sr2+(aq) + 2NO3-(aq) ------> SrSO4(s) + 2Na+ + 2NO3-(aq)
Net-ionic equation:
SO42-(aq) + Sr2+(aq) ------> SrSO4(s)
