What is the ionic form of the following unbalanced equation mno2 + HNO2=mn (NO3) 2+H20

In order to write the ionic equation, we must first assess the fact that MnO₂ is a solid, which does not dissociate into ions. Moreover, water will exist in its liquid form. Nitrous acid and manganese nitrate will exist as ions. Thus, the equation is:

MnO₂ (s) + H⁺ (aq) + NO₂⁻ (aq) → Mn⁺² (aq) + NO₃⁻ (aq) + H₂O (l)
