YACHT: Net ionic equation, now how do i find molar volume?

[MikeMike]

the equation is

A) 2HCl (l) + CaCO3 (s) + H2O (l) --> 2H2O (l) + CaCl2 (aq) + CO2 (g)

now i need to figure the net ionic out.

would the net ionic be

2HCl + CaCO3 --> H2O + CaCl2 + CO2??

n.I. is one of the things i have yet to fully grasp in chemistry.

now, what type of equation do i need for molar volume? do i need the combined gas laws? or Boyles law, or what?

crap it's been a while since i've done these, but shouldn't it be:

Cl- + Ca^(2+) + CO3^(2-) --> Ca^(2+) + Cl- + CO2

dohhhh, completely forgot about that , spliting up the compounds into the elements.

haha, yah well that's a start. but i know my answer is wrong since it's not balance. i'm missing something.....

What you do is take the soluble compounds on both sides and split them up into the elements (leave the ones that are solid in water alone). Then, remove the same elements on both sides - in effect, subtract them out. The elements/compounds that are left make the net ionic equation.

 

[MikeMike]

so it would become

H2(+) + CO3 (2-) --> H2O + CO2 ?
