NH4OH+HCLO4<br> Total ionic
Serggg [28]

Answer:

OH^-(aq)+H^+(aq)\rightarrow H_2O(l)

Explanation:

Hello there!

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

NH_4OH(aq)+HClO_4(aq)\rightarrow NH_4ClO_4(aq)+H_2O(l)

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

NH_4^++OH^-+H^++ClO_4^-\rightarrow NH_4^++ClO_4^-+H_2O(l)

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:

OH^-(aq)+H^+(aq)\rightarrow H_2O(l)

Best regards!

Summarize Mendeleev and Moseley's contributions to the history of the periodic table.
timofeeve [1]

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
