Electrostatic Series and Charging by Friction Review The electrostatic series is used to determine the charge on objects charged by friction. Objects at the top of the electrostatic series have a weak hold on electrons and are electron givers. These objects lose electrons and become positively charged. Objects at the bottom of the electrostatic series have a strong hold on electrons and are electron takers. Objects at the bottom of the series gain electrons and become negatively charged. The object

Hugh Kim Lab Report: Stoichiometry Lab 1. Prelab Part1. 1) Create no waste = The principle that encourages chemists to not create waste at the first place rather than cleaning it up afterwards effectively shifts the chemistry more environmentally conscious‚ as creating no waste would make the experiment efficient; the reactants will be reduced to only the essential ones and the product will be maximized‚ a change that would make the experiment economic. Also‚ if chemists aim to
