Hey, at least you know that.

Airness thought that carbon dioxide was HO3.

HSC_SuCkSsS, here are some revision questions I'm making up on the spot:

Dreamerish*~'s head said:
1. Describe the equilibrium system involved in the Haber process.

2. Describe the use of Atomic Absorption Spectroscopy (AAS) in detecting concentrations of metal ions in solution.

3. Assess the significance of AAS in contributing to scientific knowledge of trace elements.

4. Describe similarities and differences of the properties of polyethylene and polystyrene, and relate these to their structures.

5. Explain the formation of acid rain.

6. Identify the factors that affect total dissolved solids in water.

7. Identify and elaborate on the effects of acid rain.

8. Outline the steps of water purification and assess the effectiveness of this system.

9. Describe how membrane filters purify water.

10. Outline the process of titration, and preparing a standard solution.
Answer these correctly, and you will get invisible rep. :)

Losers.

I chose Modern over Chemistry and I'm loving every minute of it.

Today I finished my last exam for this week and am euphoric. Go on, touch me.

1. N2(g) + 3H2(g) (equilibrium sign) 2NH3(g) + Energy

increase pressure = increase in yield rate since the molar ration of left to right is 4:2
increasing temperature = lessen yield rate as equilibrium moves to the left producing more nitrogen and hydrogen
