4Al (s) + 3O2 (g) --> 2Al2O3 (s) If 31.7 g Al and 25.5 g O2 are available, which one is the limiting reactant when forming aluminum oxide?
Give the chemical formula for the limiting reactant only. No numbers or physical states!

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.)
