2. NH4+ →H+ and what ?
3a. For the Lewis structure the N is in the center and you will have 7 pairs of electrons to work with. All single bonds with one pair of lone pair.
b. this is the structural formula with the chloride ion attached . Draw the Lewis structure just for the hydroxyl ammonium ion only. Remember what the positive will do to the number of valence electrons.
c. NH3OH+ + H2O → name the products
4. Just by looking at the equation of problem 2 you can tell what is being produced to determine its acidity. Remember that Cl- is a weak ion and remains a spectator and does not get involved. Therefore NH4+ is the major species. Problem #4 on the other hand is producing what, to determine if its acidic or basic. Again the Cl- ion does not get involved.
5a. The reaction is
CaCl2 + NaCO3 → 2NaCl and CaCO3
Using the molarity equation calculate the moles needed of sodium carbonate than the volume of calcium carbonate.
b. The reaction is
2HCl + CaCO3 → Ca(HCO3)2 + Cl2
