This is because a chemical reaction takes place causing a change in the milk and the nail. In fact, regular body processes such as respiration and digestion are also chemical reactions. A chemical reaction is expressed using a chemical equation. Let’s dive in and learn about chemical reactions and equations. Chemical Reactions Station 2: Students will determine if a chemical equation demonstrates the LCM by determining whether it is balanced or not. Balancing Chemical Equations Station 3: Students will practice the writing portion of the test by using a rubric to evaluate answers and then creating their own answer. • An arrow separates the reactants from the products. The arrow head points towards the products and indicates the direction of the reaction. Skeletal chemical equation: A chemical equation which simply represents the symbols and formulas of reactants and products taking part in the reaction is known as skeletal chemical equation for a reaction. To write the equation in such manner is called as word equation. Another method to write chemical reaction; Mg + O 2 → MgO. This is symbolic form to write chemical equations. There are two part of a chemical reaction. Reactants: The substances that undergo chemical change in the reaction are the reactants. Example from above equation. Mg and ...
