Learn the basics about the atom economy principle of Green Chemistry, as a part of environmental chemistry. A reaction with a high atom economy is one where all of the atoms in the reactants are included in the final, desired product. Such a reaction would have little, if any, waste produced. A
Think of a spanner loosening a fixed nut Or a child on a seesaw Or a door opening around a fixed hinge All of these things are connected by something called moments… A moment is the turning force around a fixed pivot. The pivot is the nut, or the middle of the seesaw, or the hinge. We can have one
