In the reaction of an acid with water, a hydronium ion forms
Nutka1998 [239]
Really, ionization takes place. It means the acid dissociates in water. Ionization is just a fancy way of saying dissociation. Always think easy. 

Definition of IONIZATION: The process describing the dissociation of an acid in water.

If it ionizes or dissociates completely in water, then it shows that hydronium is a STRONG ACID. And if it ionizes partially, that shows hydronium is a WEAK ACID.

So, the answer will be choice B. by a process called ionization

A rock has a mass of 15 grams and a volume of 5 cm3. What is the density of the rock?
xz_007 [3.2K]
The answers is 3.0 g/cm^3

Explanation:
You use the formula
Density= mass/volume
When they give you mass and volume.

The mass is 15 grams and the volume would be 5 cm^3.

So the density would be
15/5= 3

Please help a brother out!
White raven [17]

Answer:

Choice 'B'

Explanation:

Choice B => SCl₂ => 2 bonded pairs + 2 nonbonded pairs => 4 electron pairs => AX₄ parent => tetrahedral parent, but the shape is defined only by what's bonded to the central element that is, sulfur bonded to two Cl substrates. The electron pairs will assume positions in space (to minimize repulsion forces) like a regular tetrahedron (AX₄) but will have an AX₂E₂ geometry which is a Bent Geometry.

Suggest searching molecular geometry images online. Look for derivatives of AX₄ geometries. Example: H₂O (AX₂E₂ bent geometry; also a derivative of AX₄ tetrahedral parent geometry).
