<h2>What is chemical binding?</h2>

Chemical bonding helps to joining atoms or molecules together. It is also helps molecules of the same or different substance to get together through joining to each other . Solid , liquid, or gaseous matter can exist in the nature due to chemical bonding .

<h3>How Chemical bonds are formed?</h3>

Bonds form when atoms share or transfer valence electrons. Valence electrons are the electrons in the outer energy level of an atom that may be involved in chemical interactions. Valence electrons are the basis of all chemical bonds.

There are two primary kinds of chemical bonds that keep atoms together:

Covalent
Electrovalent/ionic bonds.

Covalent bonds have atoms which share electrons in a chemical bond.

Ionic bonds are formed by the of atoms that have opposite charges

Sodium chloride, or NaCl, is an example of an ionic bond.

Another example of an ionic bond is found in lithium fluoride (LiF). Lithium has one electron in its outer shell, and fluorine has seven electrons in its outer shell.

Diamond is a natural form of pure carbon. What number of atoms of carbon are in a 1.00-carat diamond (1.00 carat = 0.200 g)?

slega [8]

Answer:

1.004×10²²

Explanation:

The molar mass of carbon is 12 g/mol

which means that:

1 mole of carbon atoms has a mass of 12 grams.

Since, diamond is a allotrope of carbon.

Mass of 1.00-carat diamond in grams is:

1.00 carat = 0.200 g

Since, 1 mole of C contains 6.022×10²³ atoms of C

So,

12 grams contains 6.022×10²³ atoms of C

1 gram contains 6.022×10²³/ 12 atoms of C

0.200 gram contains (6.022×10²³/ 12)×0.200 atoms of C

Thus,

1 carat diamond contains 1.004×10²² atoms of C.

What type of bond is made between amino acids in the ribosome?

sleet_krkn [62]

Answer:

Peptide bonds form between the amino group of the amino acid attached to the A-site tRNA and the carboxyl group of the amino acid attached to the P-site tRNA. The formation of each peptide bond is catalyzed by peptidyl transferase, an RNA-based enzyme that is integrated into the 50S ribosomal subunit.

The Earth's mantle is

EleoNora [17]

Answer:

C. cooler than both the crust and the core

Explanation:

It is observed that at the mantle, temperatures range from estimatedly 200 °C (392 °F) around the upper boundary with the crust to approximately 4,000 °C (7,230 °F) at the core-mantle boundary.

So we can say the mantle is cooler than both the crust and the core.
