A salt can either be a basic salt or acidic salt. An acidic salt contains a weak base and a strong acid. The acid and base undergoes a neutralization reaction to produce an acidic salt and water. A basic salt contains a weak acid and a strong base. The acid and base undergoes a neutralization reaction to produce a basic salt and water.
Answer:

Explanation:
Hello there!
In this case, according to the given reactants, it is firstly necessary to set up the complete molecular reaction:

Now, by knowing that ionic species are able to ionize, we are able to write the complete ionic equation:

Whereas ammonium and chlorate ions are spectator ions because they remain the same on both sides of the equation. Therefore the total or net ionic equation would be:

Best regards!
Answer: According to Moseley, similar properties recur periodically when elements are arranged according to increasing atomic number. Atomic numbers, NOT weights, determine the factor of chemical properties.
Mendeleev realized that the physical and chemical properties of elements were related to their atomic mass in a "periodic" way, and arranged them so that groups of elements with similar properties fell into vertical columns in his table
