Based on difference in electronegativities between atoms, which is the most polar bond pair? chlorine(cl)- 3.61 sulfur(s)- 2.58 hydrogen(h)- 2.2 oxygen(o)- 3.44 fluorine(f)- 4 a. b. c. d

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)

Summarize possible ways in which phases of matter could combine to form a solution.

Achemist 16 drop copper metal from copper chloride solution. the chemist place is 0.50 g of aluminum foil in a solution containing 0.75 g of copper (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction?
