An unknown amount of magnesium with a specific heat of 1.02 J/gºC is heated to 65°C and placed in a calorimeter containing 25.0g of water at 25.0°C. The temperature of the water raises to 26.4 °C. What is the mass of the magnesium?

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.)
