LESSON 2
AP Chemistry Chapter 17 Spontaneity of Reaction Spontaneous reactions What does that mean? Some occur without any “help” Others require some “help” No.
Biochemical Unity of Life Mass difference is 100,000,000 X but at a molecular level remarkable similar. In what ways are bacteria, plants, & elephants.
