What is Chemical Bonding?Explain please.​

Chemistry
1 answer:
olga nikolaevna [1]2 years ago
3 0

Answer:

Chemical bonds are how atoms, and even molecules join together.

Explanation:

There are two main types of primary chemical bonds. While secondary links relate to molecules, primary ties are atom to atom. This answer explains basic primary bonds only.

One must comprehend what a valence shell is before I proceed. The outer electron orbital of an atom is known as the valence shell. Most of the time (except from hydrogen), atoms desire to have 8 electrons in their valence shell, thus they form bonds with other atoms to accomplish this.

<em>All bonds result in a new chemically different molecule. Now, the two types are:</em>

  1. Covalent: When two atoms combine their electrons to fill their valence shells. The atoms are joined together by this "sharing."
  2. Ionic: When one atom <em>transfers</em> an electron to another atom in order to fulfill the valence electron requirement. Because electrons have a negative charge, the atom that <em>produced </em>them gains a positive charge as a result of losing its negative charge. The atom that received the electron therefore acquires a negative charge. Because opposing charges attract, it seems sense that the charged atoms bind as a result.

What would be the volume of 0.500 mole of an ideal gas at a temperature of 273.15 Kelvins and 1 atm?
uysha [10]

Answer:

V = 11.21 L

Explanation:

Given data:

Volume of helium = ?

Number of moles = 0.500 mol

Temperature = 273.15 K

Pressure of gas = 1 atm

Solution:

Formula:

PV = nRT

R = general gas constant = 0.0821 atm.L/ mol.K

V = nRT/P

V = 0.500 mol ×  0.0821 atm.L/ mol.K  × 273.15 K / 1 atm

V = 11.21 L / 1

V = 11.21 L

9. A student observed the following reaction:
Gelneren [198K]

Answer:

The substance that remained on the filter paper is Al(OH).

Explanation:

  • Filter paper is the substance that is used in laboratory to separate the solid objects. It doesn't filter aqueous and gaseous products.
  • So in our experiment the product formed is aluminum hydroxide Al(OH)   and sodium chloride (NaCl).
  • Between two products, sodium chloride is in aqueous form as indicated in the question. So it wont remain in the filter paper.
  • Hence aluminum hydroxide being only solid product remains on the filter paper.
