Sodium metal reacts with water to produce hydrogen gas according to the following equation:
2Na(s) + 2H2O(l)2NaOH(aq) + H2(g)
The product gas, H2, is collected over water at a temperature of 25 °C and a pressure of 759 mm Hg. If the wet H2 gas formed occupies a volume of 8.11 L, the number of grams of H2 formed is g. The vapor pressure of water is 23.8 mm Hg at 25 °C.

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.)
