What is the ionic and net ionic equation?
Ca(HO)2(aq)+ Na2CO3(aq)-> CaCO3 -> (s)+ 2NaOH (aq)

I don't understand why there are two arrows?
This is what i have so far...
Ca+2OH+Na2(aq)+CO3(aq)...

  • Chemistry -

    There shouldn't be two arrows. The second arrow should be a +.
    Ca(OH)2 + Na2CO3 ==> CaCO3 + 2NaOH
