|
|
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. |
|
|

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 |
|
|
