|
Covalent bond |
Chemical bond in which two atoms share a pair of electrons |
|
Hydrogen bond |
Attractions between a Covalently bonded hydrogen atom and another taking part in a separate covalent bond |
|
Cohesion |
Property of substance that arises from the tendency of it molecules to resist a separation from one another |
|
Why is water considered a polar molecule ? |
Overall the molecule has no charge but the oxygen atoms carries a slight negative charge; the hydrogen atom a slight positive charge |
|
Considering water,Which state of matter (liquid or solid) exhibits greater density |
Water holds a higher density because Ice is less densely packed. |
|
The PH scale |
7 is a neutral. The amount of hydrogen ions in a solution. -hydrogen ions abundant in acid |
|
BUFFER |
A Buffer is a set of chemicals that can keep the Ph stable by alternately donating and accepting ions that contribute to a PH |
|
Carbon |
The most versatile because it has 4 vacancies. Can form 4 covalent bonds with other atoms. |
|
Functional group |
Is an atom or small molecular group Covalently bonded to a carbon atoms of an organic compound |
