Activation energy is the amount of energy required to start a chemical reaction. Even reactions that give off energy need a bit of a jump start to get going. Activation energy is the minimum threshold of energy needed for a reaction to be carried out....
Chemical Reactions in Everyday Life | Overview & Examples from Chapter 13 / Lesson 3 112K Learn about chemical reactions in everyday life. Understand there are many chemical reactions in everyday life and discover some examples of chemical changes. Related...
Metabolism is the process by which cells use chemical reactions to get energy from their environment. Biochemistry's findings are mostly used in agriculture, nutrition and medicine. In medication, natural chemists explore the causes and fixes of illnesses. Nutrition studies both the effects of ...

Chemical changes are very important in our lives. All the new substances which we use in various fields of our life are produced as a result of chemical changes (or chemical reactions). Some of the examples of the importance of chemical changes are given below:...
1. Atoms are the smallest units of chemical elements that enter into chemical reactions.2. Atoms consist of a nucleus, which contains protons and neutrons, and electrons that move around the nucleus (Text, Fig. 2.1).3. The atomic number is the number of protons in the nucleus; the ...
Chemical reactions that take place during the thermal breakdown of the polymer matrix in fiber-reinforced composites (FRCs) primarily control the damage process. When FRCs burn, as shown in Fig. 1b, they release volatile gases, which can react with oxygen to fuel the fire and produce smoke ...
pH sensitivity - Related to above moisture sensitivity, as samples absorb moisture the pH can change usually decrease affecting many things such as color, and even chemical structure (oxidizing nitrites to nitrates). oxygen sensitivity - exposure to oxygen can catalyze many reactions where compounds ...
