Question

Na2CO3+2HCl--->2NaCl+H2CO3?

I need the balanced equation, complete ionic eq, and net ionic. Please include states of matter. What I have trouble understanding is why the balanced equation doesnt show2 sodiums on the right side as well when i searched the answers online? How is it balanced if there is only one sodium on right and 2 on left? The way I did it here seems like its balanced to me? Also, how do you know if the number goes next to the element as a subscript or before the entire compound? I am so confused.

Answer 1

Actually you've balanced it right.The total ionic and the Net ionic equations are given as below-

So now if you look at the compound Na2CO3 in the left,it clearly contain 2 Sodium ions,to balance this you are giving a coefficient of 2 before NaCl in the right,this is how it is balanced.

Na2CO3 is a compound by its own,so we are not to control to give '2' in its subscript as the Molecular formula of Sodium Carbonate is 'Na2CO3'. To balance the two Sodium of the compound,we can give a coefficient of 2 before NaCl.
