What is double bond,triple bond,lone pair and single bond

Chemistry

AlladinOne [14]3 years ago
5 0

In covalent bonds, atoms share electrons. These shared electrons are known as, well, covalent bonds!

In a covalent bond, each atom contributes one electron, meaning that for every bond, there are 2 electrons residing in it.

Definitions:

A single bond is a covalent bond that contains 2 electrons.

A double bond is a covalent bond that contains 4 electrons

A triple bond is a covalent bond that contains 6 electrons

It's very common for atoms to not use all of their electrons while bonding, which means that some will be left out and aren't used in any bonds. These are called lone pairs.

Definition:

A lone pair is a pair of electrons that aren't used in bonding, and therefore remain with its original atom.

Explain what is meant by the phrase 'the heat death of the universe."
Vikki [24]

Answer:

See explanation.

Explanation:

Are you literally posting your entire you chemistry homework on this site, one question at a time? Anyways, the heat death refers to the second law of thermodynamics and entropy. Heat is constantly flowing from warmer to cooler objects and never the other way around. This heat flow increases entropy, which is constantly increasing. The universe will eventually disperse all of its heat energy away to continuously increase entropy and reach a limit as the temperature reaches 0 K at which point all molecular motion will cease and so will the life of the universe.
