Which molecule has a nonpolar covalent bond?
2 answers:
Non-polar covalent bonds exist between atoms of similar electronegativities.
Further Explanation:
The chemical bond is the attraction between atoms, molecules or ions that is responsible for the formation of chemical compounds. It is formed either due to electrostatic forces or by the sharing of electrons.
A covalent bond is a bond formed by the mutual sharing of electrons between the bonded atoms. It is also known as a molecular bond. Such bonds usually exist between two or more non-metals.
Types of covalent bonds:
1. Polar covalent bond
This type of covalent bond is formed when one of the bonded atoms is more electronegative than the other one. For example, the bond between hydrogen and chlorine in HCl is a polar covalent bond. In this case, Cl is more electronegative than H.
2. Non-polar covalent bond
This type of covalent bond is formed when both atoms have the same electronegativities. For example, bond between carbon and hydrogen in is a non-polar covalent bond.
3. Coordinate covalent bond
In this bond, both shared electrons are provided by the same atom. This is normally found when metals are bonded with ligands. For example, the bond formed between cobalt and ammonia in case of hexamminecobalt (III) chloride is a coordinate covalent bond.

Explanation:
If we want to convert from grams to moles, the molar mass is used. This is the mass of 1 mole. They are found on the Periodic Table as the atomic masses, but the units are grams per mole (g/mol) instead of atomic mass units (amu).
Look up the molar mass of carbon.
- Carbon (C): 12.011 g/mol
Set up a ratio using the molar mass.
Since we are converting 3.06 grams to moles, we multiply by that value.
Flip the ratio. This way, the ratio is still equivalent, but the units of grams of carbon cancel.
The original measurement of grams (3.06) has 3 significant figures, so our answer must have the same. For the number we calculated, that is the thousandth place.
- 0.25476646
The 7 in the ten-thousandth place tells us to round the 4 up to a 5.
3.06 grams of carbon is approximately <u>0.255 moles of carbon.</u>
