Tu and noke are working with a red food coloring, red #40. the stock solution has a concentration of 0.0880 m dye. noke want to makes a concentration of 0.0088 m, exactly one tenth of the original red dye solution strength. what volume of the original 0.0880 m solution should she measure into a 100.0 volumetric flask, to be diluted with water up to the line of the flask?

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.)
