Answer 1

HNO3(к) + Ag=H+AgNO3(p) + K
HNO3 + CaO=HO+CaNO3
HNO3 + Mg(OH)2=
HNO3 + CaCO3=HCO3+CaNO3

Answer 2

I can answer your question in detail. You have asked me to write ionic equations for the following reactions:

- HNO3(p) + K -> HNO3(к) + K+ - Ag + HNO3 -> Ag+ + NO3- + NO2 + H2O - CaO + HNO3 -> Ca2+ + NO3- + H2O - Mg(OH)2 + HNO3 -> Mg2+ + NO3- + H2O - CaCO3 + HNO3 -> Ca2+ + NO3- + H2O + CO2

The ionic equations are:

- HNO3(p) + K -> HNO3(к) + K+ - This reaction does not involve any ions, so the ionic equation is the same as the molecular equation. - Ag + HNO3 -> Ag+ + NO3- + NO2 + H2O - Ag -> Ag+ + e- - 2HNO3 + 2e- -> NO3- + NO2 + H2O - The net ionic equation is: Ag + 2HNO3 -> Ag+ + NO3- + NO2 + H2O - CaO + HNO3 -> Ca2+ + NO3- + H2O - CaO -> Ca2+ + O2- - HNO3 -> H+ + NO3- - O2- + 2H+ -> H2O - The net ionic equation is: CaO + 2HNO3 -> Ca2+ + 2NO3- + H2O - Mg(OH)2 + HNO3 -> Mg2+ + NO3- + H2O - Mg(OH)2 -> Mg2+ + 2OH- - HNO3 -> H+ + NO3- - OH- + H+ -> H2O - The net ionic equation is: Mg(OH)2 + 2HNO3 -> Mg2+ + 2NO3- + 2H2O - CaCO3 + HNO3 -> Ca2+ + NO3- + H2O + CO2 - CaCO3 -> Ca2+ + CO32- - HNO3 -> H+ + NO3- - CO32- + 2H+ -> H2O + CO2 - The net ionic equation is: CaCO3 + 2HNO3 -> Ca2+ + 2NO3- + H2O + CO2

I hope this helps you understand the ionic equations of these reactions. If you want to learn more about the chemistry of nitric acid, you can check out some of the web search results I found for you .
