Chemistry question ... * Chem expert required?
Sunglasses can be made from glass photochromic. when bright light strikes Photochromic glass darkens it. photochromic glass contains small amounts of AgCl cloride silver and copper (1) chloride, CuCl. In the presence of bright light, silver chloride decomposes into silver atoms that make the glass go dark and chlorine atoms. AgCl -> Ag + Cl chlorine atoms react immediately with copper (1) chloride to cioppper (II) chloride CuCl + Cl - CuCl 2> When the exposure to bright light fractions, the silver atoms reduce copper (11) caught in copper chloride (1) chloride and silver chloride. (A) calculate the maximum mass of money that can be formed When 0.312g if the silver chloride decomposes. (B) Explain why the reaction of copper chloride and a chlorine involves both oxidation and reduction (c) construct the equation of the reaction between silver and copper1chloride. Sory i typed this shit in a hurry .. plz answer questions .. thnx
No expert needed .... basic chemistry here. a) Start with your name (0.312g AgCl) and solve moles AgCl. Then, using a molar calculate moles of Ag, and last, the use of MM to solve for g Ag Ag b) Please read on redox reactions! They always occur together, since a compound / atom loses an e-(oxidation) while the other gains (reduction). Remember: LEO says GER (lose e-ox =, gain e-=.. red) C) silver atoms reduce copper (11) chloride return copper (1) chloride and silver chloride. Everything you need to do is to put the symbols for the elements of balance .... your expenses (ie Copper II 2 + load), then the balance of your equation.
