The Mg(NO3)2(аq), when present in grоundwаter, cаn react with cоmpоunds such as tin(II) fluoride, SnF2(aq), found in improperly disposed man-made garbage. Chemical Species 1 Mg2+(aq) 5 Sn2+(aq) 2 NO3−(aq) 6 F−(aq) 3 Mg(NO3)2(s) 7 Sn(NO3)2(s) 4 MgF2(s) 8 SnF2(s) Using the numbers of the chemical species above, identify the species that are involved in the net ionic equation for the reaction between Mg(NO3)2(aq) and SnF2(aq). Net Ionic Equation: *note: pay attention to the given coefficient for proper order + 2 → (Record as the (Record as the (Record as the first digit) second digit) third digit) Answer should be recorded as 3 digits (Ex. 123)
