How does a hydronium ion molecule form?
a) evaporation.
b) two water molecules bonded.
c) a water molecule gained an hydrogen ion from another water molecule.
d) a hydrogen molecule bonded with an oh- molecule.
e) a water molecule split in half

C

Explanation:

Attached is the structure of a hydronium ion.

A is not the answer since evaporation is a phase change, not a structural change.  We are looking for a structural change since we are trying to form a hydronium ion.

B is not the answer since two water molecules bonded together would not produce the attached structure. It would produce a structure with two oxygens and four hydrogens.

C is the answer since water bonding to another hydrogen produces a hydronium ion.

D is not the answer since this combination would produce water.

E is not that answer since splitting a water molecule in half would take from the structure when you are actually supposed to add to it.

Hello thereone of the following properties was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version. which property fits this description? answer: atomic mass  was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

Is there any options, for this
