How do you write a chemical equation?
Key PointsIn a chemical equation, the reactants are written on the left, and the products are written on the right.The coefficients next to the symbols of entities indicate the number of moles of a substance produced or used in the chemical reaction.
What is chemical reaction and equation?
Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
What is an equation in math?
An equation says that two things are equal. It will have an equals sign “=” like this: 7 + 2 = 10 − 1. That equation says: what is on the left (7 + 2) is equal to what is on the right (10 − 1) So an equation is like a statement “this equals that”
