有冇發覺chem bio 難中point?因為你冇skillsspecific knowledge back up

用13 chem paper 第6條short essay
Q:briefly describe how the polypropene can be produced from naphtha
1.naphtha 係咩黎?(specific knowledge)
2. process involved (寫中都可能冇分,因為有skills)
3.link up naphtha and polypropene (naphtha->propene->polypropene)


到Bio13 第8條

2 25 2
3 40 8
4 38 10
5 20 20
6 18 35
7 15 33

2.the characterisic of region of desiccation
3.what they would face in the region of desiccation
