The speed of chemical weathering depends on:

water freezing
amount of wind
soil depth

In this experiment you were asked to present three possible mechanisms. describe those mechanisms here and include drawings of those mechanisms. how will the bromination of trans-cinnamic acid and trans-stilbene allow you to distinguish between the three possibilities? what would you expect to find in your data in each scenario?

2. given that most biochemical (other than coal) rocks react with hydrochloric acid, what does that tell you about organisms?
