This is important for the students to appreciate the knowledge of chemistry that is still new for themselves. Personally‚ I think that this chapter is an interesting chapter as it revealed the way of scientist produces the material around me. It also gives me new knowledge of the uses of chemical substances that I usually found in the laboratories. I hope‚ by learning this chapter‚ I will be more interested in learning chemistry as it will help me in the future. All the equations from this chapter
