The correct answer is fracture formation.
Fracture formation is not an indication of a chemical change.
Gas production, energy transfer are Precipitate information indications of a chemical change.
A chemical change is an irreversible process wherein there are rearrangements of the atoms in the molecules of a compound, resulting in the formation of a new compound with new chemical properties or composition.
A fracture is a fault line that divides rocks into two or more pieces. A fracture is a geological formation. Fracture is most often seen as crevice or deep fissures in rocks.
Answer:
Because the value of K is huge.
Explanation:
The tautomer is a kind of isomer in which exist an equilibrium between a ketone and an enol, or between an aldehyde and an enol. So, in the enolization, the ketone is the reactant and the enol is the product.
The equilibrium reaction can be characterized by an equilibrium constant, which is the ratio of the concentration of the products by the concentration of the reactants.
Because the constant K is extremely large (10¹³) we can conclude that the concentration of the product will be greater than the concentration of the reactant, in the equilibrium. It means that the concentration of the enol will be greater.
So, the ketone is unstable and forms in a great amount the more stable product, the enol.
Water b/c it is insoluble in water. it is soluble in cyclohexane and sparingly <span>soluble in ethyl alcohol.

H₂ will have the highest average kinetic energy
<h3>Further explanation </h3>
Energy because this motion is expressed as Kinetic energy (KE) which can be formulated as:
Average velocities of gases can be expressed as root-mean-square averages. (V rms)
R = gas constant, T = temperature, Mm = molar mass of the gas particles
From the two equations above, it can be concluded
- KE is directly proportional to gas velocity
- Gas velocity is inversely proportional to molar mass
So <em>the highest KE is owned by the gas with the smallest molar mass</em>
<em />
Molar mass of the gas :
A) H₂ : 2 g/mol
B) N₂ : 28 g/mol
C) O₂ : 32 g/mol
D) F₂ : 38 g/mol
So <em> H₂ has the highest average kinetic energy</em>
POH + pH = pKw
pOH + pH - pH = pKw - pH
pOH = pKw - pH.
The correct equation used to calculate pOH would be C. pOH = pKw - pH.
