<h3>ANSWER:</h3>

<h3>EXPLANATION:</h3>

An ionic compound is made up of a metal and a nonmetal. K is a metal while bromine is a nonmetal. Thus K transfers its one electron to bromine in order to form an ionic compound.

An ionic compound is composed of ions, a positive ion i.e. a cation and a negative ion i.e. an anion. The bond formed between the two elements is an ionic bond which is formed by the complete transfer of electrons from an electropositive element to the electronegative element. The electropositive element loses its electron and gains a positive charge whereas the electronegative atom accepts that electron and gains a negative charge.

In the given examples:

KBr is made up of ions

Potassium being electropositive becomes positively charged K+

Bromine is electronegative and becomes negatively charged Br-

KBr = K⁺Br⁻

What is formed when water chemically combines with carbon dioxide

solong [7]

When water chemically combines with carbon dioxide, a Carbonic acid is formed.

<u>Explanation</u>:

Carbon dioxide responds with water in a solution to form a weak acid, carbonic acid. Carbonic acid disassociates into hydrogen particles and bicarbonate particles. The hydrogen particles and water respond with the most basic minerals modifying the minerals.

Carbon dioxide and the other atmospheric gases disintegrate in surface waters. Dissolved gases are in equilibrium with the gas in the atmosphere. Carbon dioxide responds with water in a solution to form the weak acid, carbonic acid. Carbonic acid disassociates into hydrogen particles and bicarbonate particles.

The hydrogen particles and water respond with the most basic minerals altering the minerals. The results of enduring are prevalently clays and soluble particles, for example, calcium, iron, sodium, and potassium. Bicarbonate particles additionally remain in solution; a remnant of the carbonic acid that was utilized to weather the rocks.
