Problem

A particulate-level description of an aqueous mixture shows that 2

Ca^{2+}

ions and 2

CO_{3}^{2-}

ions combine to form 2 solid

CaCO_{3}

units, while 4

Na^{+}

ions and 4

NO_{3}^{-}

ions remain dispersed and unchanged. Write the balanced net ionic equation for the reaction represented.
