Determine the reaction between magnesium iodide and potassium chlorate and figure out the net ionic equation  

Magnesium iodide is composed of magnesium (Group 2A → +2 charge → Mg2+and iodide (Group 7A anion → -1 charge → I-). The molecular formula will appear as MgI2. Recall that for ionic compounds, the charge of the ion goes to the subscript of the counterion
