A glass on a window sill contains 15.7 grams of cold water at 3.5°C. As it heats up in the sun, the water gains 570 joules of
energy. The specific heat capacity of water is 4.186 joules/gram degree Celsius. What are the value of AT and the final
temperature of the water?

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.)
