Answer:

B)hydronium

Explanation:

This chemical structure is formed when an acid is disolved into water, as the cation (H+), which comes from the acid, cannot exist as such isolated in water (H20), hence the proton (H+) will be hydrated by a water molecule (H2O)

The union between H+ and H2O is due to the pair of electrons from oxygen and positive charge from H+

Answer:

H3O+ units are also known as hydronium ions. Hence the answer is option B.

Explanation:

Hydronium ions is defined as ions that contains proteinated ions and it is present in all the aqua solutions. These ions are abundant in protons and they have less electrons in them. It is because they had donated electrons to their other forms which gives a positive sign to the ion.

Hydronium ion is produced when an Arrhenius acid is mixed with dihydrogen oxide. This iron is found in universe like in comets, interstellar things, etc.

A species of beetle expresses a pigment protein as an adult but not as a juvenile. The pigment is encoded by the gene PIG. A pro

Deffense [45]

Answer:

The KID protein is responsible for the no pigmentation at the juvenile stage. When the KID protein inhibits in the adult state, the pigmentation occurs in the body. This might occur because the KID protein acts as the repressor molecule and acts as a negative regulator of PIG protein.

The KID protein is responsible for pigmentation an adult stage. Any mutation in the KID gene might result in the loss of pigmentation in the adult. The KID gene is responsible for the binding of the KID protein and mutation in this gene can lead to the arrest of KID protein. The protein is unable to release and PIG continuously repressed in the adults.

Describe the bonding between ionic compounds

chubhunter [2.5K]

Answer:

<h2>Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.</h2>
