Answer:
π = MRT
= × RT
= ×RT
MM = mxRxT / πxL
MM = 8.00g ×0.0821×298/ 2.86×0.200L
= 342.2 g/mol

Answer:</h3>
An ionic bond is an attraction between oppositely charged ions. A covalent bond is a sharing of electrons between atoms.
<h3>
Explanation:</h3>
- Ionic bonds and covalent bonds are both types of chemical bonds.
- Ionic bonds are types of chemical bonds that are formed between a metal and non-metal atoms.
- Ionic bond formation involves the transfer of electrons from a metal atom to a non-metal atom. For example from a potassium atom to a chlorine atom.
- Metallic atom loses electrons to form a positively charged ion and non-metallic atom gains electrons to form a negatively charged ion.
- The electrostatic attraction between the oppositely charged ions results in an ionic bond.
- A covalent bond, on the other hand, occurs between non-metal atoms as a result of sharing electrons. For example, in a chlorine molecule, two chlorine atoms share electrons to form a chlorine molecule.
A.
An amine refers to a nitrogen-based compound. Since A is the only option with nitrogen, that would be the answer.

The gamma ray photons make their arduous journey to the surface of the Sun, they are continuously absorbed by the solar plasma and re-emitted to lower frequencies. ... By the time they get to the surface, their frequencies are mostly only within the IR/visible light/UV spectrum. Nov28,2020
Answer:
Diffusion of Innovation (DOI) Theory, developed by E.M. Rogers in 1962, is one of the oldest social science theories. It originated in communication to explain how, over time, an idea or product gains momentum and diffuses (or spreads) through a specific population or social system
