Sec Sch Chapter 17 Energy Changes
Chemists like Humphry Davy and Svante Arrhenius played important roles in providing a comprehensive understanding of what happens in chemical reactions. A new era of electrochemistry started when Humphry Davy (1778–1829), a British chemist, built a powerful battery to pass electricity through molten salts. This era resulted in advancements made in chemistry such as this chapter on energy changes. This chapter is a difficult chapter for most students as it introduces a unit of measurement that most students will not be used to. That being the unit of measurement for energy or Kilojoules. Having this new unit might possibly confuse or scare students initially. But once that hurdle is overcome. This chapter becomes a lot simpler. Which is what this course aims to do. With simple to understand lectures as well as challenging exam questions taken from schools all across Singapore. Students will be able to seamlessly overcome what was once a massive hurdle and go on to ace this chapter. Making even Humphry Davy proud.
