The net ionic equation for this reaction is: Follow 1 Add comment Report 1 Expert Answer Best Newest Oldest John M. answered 07/24/20 Tutor 4.9 (93) MS in Chemistry with over 30 years teaching experience. As the reacting metal is magnesium, then the product must be a magnesium salt. One last thing to consider. We therefore write the state symbol (s) after the compound that precipitates out of solution.If you are unsure if a compound is soluble when writing net ionic equations you should consult a solubility table for the compound._________________Important SkillsFinding Ionic Charge for Elements: https://youtu.be/M22YQ1hHhEYMemorizing Polyatomic Ions: https://youtu.be/vepxhM_bZqkDetermining Solubility: https://www.youtube.com/watch?v=5vZE9K9VaJIMore PracticeIntroduction to Net Ionic Equations: https://youtu.be/PXRH_IrN11YNet Ionic Equations Practice: https://youtu.be/hDsaJ2xI59w_________________General Steps:1. Because of its toxicity, arsenic is the active ingredient in many pesticides. Proudly created with Wix.com. ??
