it can be formed by H+ ion and an H20 molecule also the chemical formula is H30+ or in other and easier way thus formula
H+ + H20=H30+

Answer : The reaction shows the formation of hydronium ion is,

$H^++H_2O\rightarrow H_3O^+$

Explanation :

The given reactions are:

(1)
$H^++H_2O\rightarrow H_3O^+$

In this reaction, hydrogen ion react with water to give hydronium ion as a product.

(2)
$H_2O+CO_2\rightarrow H_2CO_3$

In this reaction, water react with carbon dioxide to give carbonic acid as a product.

(3)
$NaOH\rightarrow Na^++OH^-$

In this reaction, sodium dissociate to give sodium ion and hydroxide ion as a products.

(4)
$H_2O+NH_3\rightarrow NH_4^+$

In this reaction, water react with ammonia to give ammonium ion as a product.

From this we conclude that, only reaction 1 shows the formation of hydronium ion. While the reactions do not shows the formation of hydronium ion.
