B.)H3O+
C.)OH-
D.)H+

Answer 1

B) H30+ is the answer, hope that helped

Answer 2

Answer: Option (B) is the correct answer.

Step-by-step explanation:

A hydronium ion is an ion that contains three hydrogen atoms and one oxygen atom. Formula of a hydronium ion is
`H_(3)O^(+)`.

Whereas water is a molecular compound with chemical formula
`H_(2)O^`.

Hydroxide ion has formula
`OH^(-)` and a hydrogen ion has formula
`H^(+)`.

Therefore, we can conclude that out of the given options
`H_(3)O^(+)` is a hydronium ion.
