Final Paper – A Silver Dish by Saul Bellow In chaos theory‚ the butterfly effect is a term used to describe how such irrelevant details can drastically change future events. The butterfly effect is a way of describing how‚ unless all other factors can be accounted for‚ large systems such as weather remains impossible to predict with total accuracy because of the countless unknown variables. Any complicated system may be vulnerable to drastic change due to small details being added or erased

Objects that are made from silver or coated with it‚ by time‚ start to tarnish. Tarnish is s chemical process that leads to dullness of color of the surface of the metals such as silver‚ gold‚ aluminum‚ iron‚ brass and copper. This reaction mostly happens because of the air pollution and/or moisture. To remove the tarnish from the metals‚ the silver objects must undergo a chemical reaction. Thus this chemical reaction would make the silver object look shiner. The chemical reaction to clean up the

Silver Mirror Experiment Background: This experiment was first conducted by Bernhard Tollens‚ it is used to determine whether a carbonyl containing compound is an aldehyde or a ketone. An aldehyde is a compound containing a formyl group (CHO).The experiment involves diamminesilver complex and a chemical reagent (also known as “Tollens’ reagent”) which in this case is glucose. In a successful experiment a reflective silver metal should precipitate‚ with characteristics identical to that of a mirror’

of silver as a national currency. Because of the present economic situation‚ people have not had time to think about the subject. The intention of this essay is to inform all those who until now have not reflected on this proposal. I believe Mexico should adopt a silver standard because Mexico is the biggest producer of silver in the World‚ Mexico has had success using the silver standard in the past‚ and silver is a standard without risks. The first reason why Mexico should adopt a silver standard
