Let me know if this helps :)
Answer:
+ => +
Explanation:
Nitric acid reacts with sodium carbonate to form sodium nitrate, carbon dioxide and water.
Sodium carbonate + nitric acid => sodium nitrate + water + carbon dioxide
2HNO3 + Na2O3 => 2NaNO3 + CO2 + H2O
So the net ionic equation is as follows:
+ => +
The sodium ion and the nitrate ions are not involved in the net equation because they are not changed in the reaction.
