Hello students, in this video we will discuss about molecules.
00:04
First, organic molecules are made up of carbon, hydrogen and oxygen.
00:17
Phases, acids, salts and water are all inorganic compounds.
00:32
Next, lemon juice has a ph of 2 which is the most acidic of the options provided.
00:57
A base removes hydrogen ions and an acid releases hydrogen ions.
01:20
Water has a high heat of vaporization which means that it takes a lot of energy to vaporize it.
01:50
This makes it good coolant.
01:56
Water also dissolves many substances, participates in chemical reactions and serves as an excellent lubricant.
02:26
A substance with a ph that is greater than 7 is alkaline.
02:39
Alkaline substances have a higher concentration of hydroxide ions than acids.
02:54
The primary high energy molecule formed and used in the cell is atp.
03:22
Atp stands for adenosine triphosphate...
