What is orbitals in the chemistry definition

2 answers:

Orbitals or otherwise fully known as Atomic orbitals are regions of space around the nucleus of an atom. This is also where an electron believed to be found. The atomic orbitals allow atoms to make covalent bonds.

Hope I could help! :)

Good afternoon!

An orbital, in chemistry, can be described as a layer where an electron is expected to be found, around a nucleus of an atom.

Atoms contain 3 parts - protons, neutrons, and electrons. The protons and neutrons stick together in the center, while the electrons are flying around the entire nucleus (protons+neutrons).

The location of these electrons is unknown, as they fly around, however there is a "most likely found" location.

These are the orbitals. They are the areas where the electron is most likely to be found.

Good luck!

toms of elements at the top of a group on the periodic table are smaller than the atoms of elements at the bottom of the group.

Novosadov [1.4K]

Answer:

Atoms of elements at the top of a group on the periodic table are smaller than the atoms of elements at the bottom of the group. ... The valence electrons of the larger atoms are farther from the nucleus and are easier to remove, so the metals near the bottom are more reactive than those at the top.

Aluminum and cloride undergoes a synthesis reaction if 8molnof Al reacts with 10mol of cl, what is the maximum amount of AlCl3 c

Inessa [10]

Answer: The mass of $AlCl_3$ produced is 889.38 g

Explanation:

We are given:

Moles of Al = 8 mol

Moles of $Cl_2$ = 10 mol

For the given chemical reaction:

$2Al+3Cl_2\rightarrow 2AlCl_3$

By stoichiometry of the reaction:

If 3 moles of chlorine gas reacts with 2 moles of Al

So, 10 moles of chlorine gas will react with = $\frac{2}{3}\times 10=6.67mol$ of Al

As the given amount of Al is more than the required amount. Thus, it is present in excess and is considered as an excess reagent.

Thus, chlorine gas is considered a limiting reagent because it limits the formation of the product.

By the stoichiometry of the reaction:

If 3 moles of $Cl_2$ produces 2 mole of $AlCl_3$

So, 10 moles of $Cl_2$ will produce = $\frac{2}{3}\times 10=6.67mol$ of $AlCl_3$

The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

We know, molar mass of $AlCl_3$ = 133.34 g/mol

Putting values in above equation, we get:

$\text{Mass of }AlCl_3=(6.67mol\times 133.34g/mol)=889.38g$

Hence, the mass of $AlCl_3$ produced is 889.38 g

Solubility is determined by the molecular or ionic structures of the solute and the solvent, and by the _________ that hold toge

Natalija [7]

Answer:

Solubility is determined by the molecular or ionic structures of the solute and the solvent, and by the intermolecular forces that hold together the particles of each substance

Explanation:

- Ionic bonds and covalent bonds are sort of intermolecular forces

-State of matter does not hold together the particles of each substance

Determine the mass of each of t he following:

EastWind [94]

Explanation:

Mass of compounds = Moles of compound × Molecular mass of compound

a) Moles of LiCl = 2.345 mol

Molecular mass of LiCl = 42.5 g/mol

Mass of 2.345 moles of LiCl = 2.345 mol × 42.5 g/mol = 99.6625 g
