The products of self-ionization of water are

Answers

The products of self-ionization of water are H3O+ or H+ and OH-

The auto-ionization constant of water is equal to the product of the concentration of H3O+ andOH- . The value of w depends only on temperature. It can be change according to the temperature.

The products of self-ionization of water are OH- and H+.
OH- is the hydroxide ion and H+ is the hydronium ion.

How does CFL lamps help in conservation of energy?

Answers

CFL means compact fluorescent lamp

It can save five times its purchase price in electricity cost because it contains toxic mercury that is equivalent in working: electrons that are bound to mercury atoms are excited to states where they will radiate ultraviolet light as they return to lower energy level, this ultraviolet light will be converted into visible light as it strikes to the coating of the bulb. Like LED that is high-efficiency house lighting.

What is internodes in chemistry

Answers

Explanation:

In chemistry, internodes refer to the points in the structure of a molecule or molecular chain where carbon atoms are located. Internodes are carbon atoms that are directly connected by a single bond. These carbon atoms are often called "C" followed by a number indicating their position in the chain. Carbon atoms that are not internodes are called "terminal carbons" and are bonded to other atoms or chemical groups. The structure of internodes and terminal carbons is important for understanding the geometry and reactivity of organic molecules.

Which of the following two elements will likely form a covalent bond? N and O K and Cl Li and F Na and Sr

Answers

Covalent bonds are also called molecular bonds. These chemical bondings involves atoms sharing electron pairs. Covalent bonding usually happen between 2 non-metals. Non metals are usually found in the left and right most sides of the periodic table. Hence, the answer will be A. N and O since both elements are non-metals.

Answer: N and O

Explanation:

An ionic bond is formed when a metal completely transfers its valence electron to a non metal.

Covalent bond is formed by sharing of electrons between two non metals.

A. N and O both are non metals and thus form a covalent bond.

B. K is a metal and Cl is a non metal and thus form an ionic bond.

C. Li is a metal and F is a non metal and thus form an ionic bond.

D. Na and Sr both are metals
