We can predict formula of ionic compounds by:
- Take a look at where the elements are listed on the periodic table.
- The amount of electrons that an element would need to gain or lose in order to resemble an atom of a nearby noble gas is one of the similarities that atoms in the same column as one another (group) tend to display.
- Alkali metal group I ions have +1 charges.
- Alkaline earth metals (group 2 ions) have a +2 charge.
- Nonmetal group 6 ions have a charge of -2.
- Halides in group 7 have a -1 charge.
- The charges of the transition metals cannot be predicted in a straightforward manner.
- Check out a table of charges (valences) to see potential values. The +1, +2, and +3 charges are most frequently employed in beginning and general chemistry courses.
- Keep in mind that the positive ion is always stated first when writing an ionic compound's formula.
These are the few guidelines we can use to product formula.

Answer:
i) Dilute hydrochloric acid will react with Ammonia to form ammonia salt.
ii) dilute hydrochloric acid will react with soduim hydroxide to form sodium chloride and water
iii) dilute hydrochloric acid will react with calcuim carbonate to form Calcium chloride, Carbon dioxide and water.
Explanation:
CHEMICAL EQUATIONS :
I) HCL + NH3 = NH4Cl
ii) HCL+ NaOH = NaCl + H2O
iii) HCL + CaCo = CaCl2 + CO2 + H2O
hydrogen (H2),and oxygen (O2),, that is the answer
