Question

A double replacement reaction occurs when aqueous potassium iodide and aqueous mercury (I) nitrate are mixed. What is the correct balanced chemical equation for this reaction? (1 point)

KI(aq) + HgNO3 (aq) yields KHg(aq) + INO3(s)
KI(aq) + HgINO3 (aq) yields KNO3 (aq) + Hg(s)
KI2 (aq) + HgNO3 (aq) yields KNO3 (aq) + HgI2 (s)
KI(aq) + Hg2NO3 (aq) yields KNO3(aq) + Hg2I(s)
