How do you calculate the pressure of hydrogen gas collected over water? To obtain the gas pressure, subtract the vapor pressure of water from the total pressure. EXAMPLE: A 325 mL sample of gas is collected over water at 26oC and 742 mm Hg pressure. Calculate the volume of the dry gas at STP. The […]

Some globes have a control knob that varies the amount of power going to the center electrode. What happens if […]
Does benzene absorb UV light?
Does benzene absorb UV light? Note that both benzene and naphthacene absorb light in the near ultraviolet but that the latter does so much more intensely. A solution of naphthacene will absorb almost 100 times as much light at 250 nm. as a solution of benzene of the same molar concentration. Can light break bonds? […]
