Trial SPM Wilayah Persekutuan Chemistry Paper 3 2010

Yesterday, my students sat for the exam. There are only two questions.

1. Determining heat of displacement of copper by different metals.
2. Planning an experiment to determine the position of carbon based on it ability to reduce metal oxies.

The first question were somehow the same like one of the past year question(heat of neutralisation).  My both classses did carry out this experiment. But I wonder whether they can answer the question with high score. Best of luck to all of them which is going to sit for Chemistry Trial SPM Paper 1 & Paper 2 tomorrow!
