The one who coined this Pendrive for Chemistry topics is a genius! It helped me and a lot of students to learn while doing supplemental reading. It gives us additional information from lessons taught in college. It helps us to understand better what the professor is talking about. We don’t have to stare at him blankly and scratch our heads anymore. We can now determine quantitative data involving relationships between reactants and product in their chemical reaction. How to balance the equation by putting necessary number of atoms in the problem. Who knew chemistry would be this easy to discern!
