Value of OEBs to the industrial hygiene process (ERAM). Reactants. Suppose that you are in a car factory. . In . order to assemble a car, 4 tires and 2 headlights are needed (among other things). . In . this example, imagine that the tires and headlights are reactants while the car is the product formed from the reaction of 4 tires and 2 . Stoichiometry. !. So far. In all our reactions, we assume both reactants get used up. We assume both reactants provided are pure. We rarely see these two.. Limiting reagents. Percent Purity. Percent Yield. Bon Appetite. Suppose you are a chef preparing . F. rench toast for a group of people. You make French toast the way you have always made it: . one egg for every three slices of bread. . You never waiver from this recipe, because the French toast will be either too soggy or too dry. There are 8 eggs and 30 slices of bread in the pantry.. The Risk-Limiting Audits Working Group is a self-organized group of election officials, researchers, and advocates, created to explore risk-limiting audits as an election verification mechanism.
