Can there be two hydrogen bonds between two molecules of NH3? For instance, one of hyrdogen from one NH3 molecule bonds through hydrogen bonding with the nitrogen (N) of te second molecule. And then one of the hydrogens from the second molecule connects with the nitrogen atom of the first molecule. Is this possible? Why?


Thanks,

So im determining the amount of Na2CO3 in a sample of soda ash by titrating it with HCl. I need help coming up with the equations. This is what I know:
The reaction occurs in 2 stages the first titration with one indicator and the second titration with another indicator. Theres supposedly 6 equations including the complete and net ionic equations...I know that the final equation would be this:

Na2CO3 + HCl = H20 + NaCl + CO2
because the H2CO3 is not stable or w/e so it changes to CO2. I need help coming up with the other different equations for each stage I started with stage 1 and tried this:
Na2CO3 + HCl = NaCl + NaHCO3
but i dont know if thats correct and i dont know where to progress from there to stage 2. Please help! Thanx!
