Q. Atmospheric pressure on the peak of Mont Everest can be as low as 0.20 atm. If the volume of an oxygen tank is 10.0L, at what pressure must the tank be filled so the gas inside would
occupy a volume of 1.2 x 10 3 L at this pressure?

How do you know when a chemical reaction has occurred

How many moles of cu are needed to react with 5.8 moles of agno3? cu + 2 agno3 → cu(no3)2 + 2 ag
