The ionic equation and net ionic equation and balance equation:

Question

A) Ca(OH)2 + HNO3 -->
B) H2SO4 + Na2CO3 --->

Answer 1

molecular:
Ca(OH)2(aq) + 2HNO3(aq) ==> Ca(NO3)2(aq) + 2H2O(l)

ionic:
Ca^2+(aq) + 2OH^-(aq) + 2H^+(aq) + 2NO3^-(aq) ==> Ca^2+(aq) + 2NO3^-(aq) + 2H2O(l)

NET ionic:
Just cancel the ions that are common to both sides to leave
2H^+(aq) + 2OH^-(aq) ==> 2H2O(l)
