When you mix copper‚ silver‚ and nitrate together‚ you will end up with silver nitrate solution will turn blue (it has become copper nitrate). On the piece of copper‚ there would be a coating of solid silver. If a chemical reaction is going to be observed when chemicals are mixed‚ heated or any other means of altering the substance‚ then we will be able to predict the products formed. If it is observed that in the original versus the changed substance no new substances are formed‚ the change is reversible

I mostly agree with Ashley’s opinion‚ but I do not believe Silver Linings Playbook is a formalistic movie. This is not a formalistic movie because there are no distortions or manipulations of reality (Giannetti 7). Also‚ formalistic movies use highly manipulated images that they look so different from the real thing ( Giannetti 524). They want the manipulated images to look beautiful or attractive to the eye (Giannetti 524). Silver Linings Playbook does not use manipulated images because the images

Although‚ Stingy Jack did die during those ten years‚ but God would not

Copper-Silver Nitrate Reaction Introduction In this experiment copper wire will be placed in a solution of silver nitrate. This single replacement reaction will produce a blue solution of copper II nitrate and solid silver. By weighing the reactants before the reaction‚ the mass of silver produced can be predicted. This theoretical yield can be compared to the actual yield of silver. Purpose Students will compare the theoretical mass of silver with the actual mass of silver from the single

China. Enormous quantities of opium made their way to China‚ swelled by the number of merchants involved. By the 1820s‚ the value of opium coming into China exceeded the value of goods exported out. Thus‚ the Chinese had to pay silver in addition to their goods to get opium. Silver shortages began to hurt peasants. To stop the trade‚ the Qing emperor sent a special commissioner‚ Lin Zexu‚ who froze all legitimate trade in Canton until foreign merchants handed over their opium stores. The opium traders

1/23/12 Silver Trade DBQ The global trade of silver had a devastating affect on the Chinese economy because China did not have the supply of silver that was needed to support their economy so they became dependent on the trade that the Europeans brought (1‚3‚7‚8). In Europeans states like Spain and Portugal we see their economies benefiting from the increase of the global silver trade because they controlled silver mines in the Americas and India (2‚4‚6). In china the increase of silver trade brought
