独中教吗？国中似乎必须是教育文凭。我也是化学系生。翻开报章有点无奈。

对！我在独中教，因为本人没有教育系文凭，不能在国中任职。

我也赞同你的说法，其实化学系毕学生也蛮难从报纸上找到一份称心如意的工作。

当然还有其他原因而执教鞭。

每样东西都好像和化学有关，以为必然容易找到工作，
后来才知道事实并非如此，
相关行业找的不是工程就是地质学的，
再者就是经验，
真的是问天天无语。

TonyDaisie

其实我觉得工作机会是有的。所有的化学厂甚至没关系到化学的都需要化学师。例如电子厂要化学师来处理废物。还有在政府鼓励实行的ISO也需要化学师（REGISTERED CHEMIST）。

至于很多毕业生找不到工可能是工厂没严格的实行ISO,聘请TECHNICIAN还是只有SPM科学系的员工。

TonyDaisie

很高兴终于看到有人交流了。欢迎各位对化学有兴趣的朋友。
我是ANALYSIS的。ANALYTICAL CHEMISTRY

bai

要经验，刚毕业的怎么可能有？IKM更不用说啦。所以说毕业生还是失业。谁不知道日常生活中每样都是化学？用的不及读的百分之二十，偏偏用的又不够专精。
一份工作数百人申请， 很无奈的。TonyDaisie 工作很久了？分析化学师？很厉害哦。分析化学看似容易，可是每一个仪器背后的理论还有应用并不像想象中那么容易。好比NMR.不是学士生有机会碰到的。很多的分析也只能靠经验，心得和揣测。AS也是。上课讲得容易，打开来看，哇。。那里只是几个部分而已？都是那句，经验啊经验。

TonyDaisie

同常学生们会学到 interpret data.不过没动到instrument,所以了解不深。渐渐地忘了。其实是有学到乐理的。

你是学生吗？

bai

毕业了。刚刚。可是还是觉得自己很多不足。另一种无奈。
原来这里这么多化学毕业生，可以解释下orgel diagram 和graph of energy versus Δ吗？

哇，好像有听过。。。。但是忘了

TonyDaisie

只知道是用来算energy而已。其他的都忘了。你有接触这方面的工作吗？

bai

没有。只是之前一直都不甚了解，一直都很想知道。

gates_way

请问各位前辈，
Fe+ HNO3
Zn+ HNO3
Cu + HNO3
会有什么reaction??
因为我在网上看到很多不同的答案。

TonyDaisie

基本上是根据它们的浓度。以下都可能发生：

3Zn + 2NO3- +8H+ -> 3Zn+2 + 2NO + 4H2O or
Zn + 4 HNO3 -> Zn(NO3)2 + 2 NO2 (g) + 2 H2O

谢谢你的回答。
还以为这帖一定会沉。

TonyDaisie

我不会让它沉的。你也不会吧？

哈。对呀！
谢谢分享哦！
蛮多的人都说化学都很难，为什么呢？
我本人蛮喜欢化学的，现在是pre-u学生，开始对organic有一点棘手。

TonyDaisie

不会难啦！只要多读和了解。
不过ORGANIC真的需要背很多东西。
如果上了大学又选回ORGANIC的话，应该要学会看SPECTRUM了。
马来西亚的大学ORGANIC多数都是在研究植物的成分（HERBA).

TonyDaisie

祝个位化学的网友新年快乐！！！！

心想事成！！！
