How many moles of nitrous oxide gas will occupy a volume of 9.30 L at 22C and a pressure of 2.2 atm? Work must be shown

Calculate the molarity of 48.0 ml of 6.00 m h2so4 diluted to 0.250 l .

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.)

The melting point of sulfur is 115 °c and its boiling point is 445 °c. what state would sulfur be in at 200 °c?
