What is a Chemical Reaction?. A Chemical reaction occurs when ever a chemical bond is formed, broken or rearranged.. A chemical reaction will always create a new substance.. Energy and Chemical Reactions. Jennie L. Borders. Section 11.1 – Describing Chemical Reactions. In a chemical reaction, the reactants are written on the left and the products on the right.. The arrow that separates them is called yield.. All. chemical reactions either release or absorb energy. . The energy can take many forms: . HEAT. , . LIGHT. , . SOUND. , and . ELECTRICITY. . Chemical . bonds. are the source of this energy. . TH. AND. CONGRATULATION. I . Mrs . Padmavathi. is going to take your . std. 10. th. Chemistry class.. May be this is the first time the class is commencing without direct Interaction with you all. I miss your laughing faces, curious questions during class. Hope very soon we meet and have real interactive class. .
