16/10/2018· Therefore, 2 Na ions can cover the need of one carbonate ion. So, the ratio of Na to CO3 ion should be 2:1. Now just combine the 2 ions, positive one at the front, which makes it NaCO3, make sure you do not add the charge and notice that CO3 is a molecule itself so do not remove the 3. Now because the ratio is 2:1, so the final formula is ...

25/09/2012· Best Answer. Copy. I'm pretty sure you have your formula wrong. Oxygen has a net charge of -2. So therefore, the equation must be written as 2Hg with a net charge of 2+ plus CO3 with a net charge ...
1. Due to the fact that carbon is the least electronegative element, it is positioned centrally: 2. Carbon has four valence electrons, each oxygen has six, and there are two more for the valence charge of two. This results in a total of 4 + (3*6) + 2 = 24 valence electrons. 3.
