Sample Chemical Reaction Equation In most chemical reactions, two or more substances, called reactants, interact to create different substances called products. CHEMICAL REACTION REACTANTS go IN PRODUCTS come OUT NO NEW ATOMS are created OR destroyed. (Law of Conservation of Mass) REACTANTS go I...
In this process breaking and forming bonds between atoms takes place. Compounds that interact to produce new compounds are called reactants whereas the newly formed compounds are called products. Q2 What is chemical reaction and equation? A chemical reaction is in which the bonds are broken ...
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 ...
