Liquid A is known to have a lower viscosity and lower vapor pressure than Liquid B. Use these facts to predict the result of each experiment in the table below, if you can. experiment Two 10 L glass flasks are evacuated and sealed. 25.0 mL of Liquid A are injected through the seal into one flask, and 25.0 mL of Liquid B are injected into the other flask. After 30 minutes, the pressures PA and PB inside the flasks are...

5 6 Liquid X is known to have a lower surface tension and lower viscosity than Liquid Y. Use these facts to predict the result of each experiment in the table below, if you can. experiment predicted outcome Identical wire loops are dipped into Liquid X and Liquid Y so that a film of liquid forms across the loops (like the bubble solution on a childs bubble blowing wand). The width of each loop is increased slowly and the forces...

i dont understand why the molecular weight i calculated
(42.012 g/mol) for my unknown liquid (acetone) is less than the
actual molecular weight (58.08 g/mol). what errors could i have
made in my lab that would account for the difference.
Molecular Weight of a Volatile Liquid In this experiment, an amount of liquid more than sufficient to fill the flask when vaporized is placed in a flask of measured volume and mass. The flask is then heated in a boiling...

Mass of Magnesium strip Use the length of your magnesium strip and the mass per m provided by your TA to calculate the mass of your magnesium strip. Make sure to convert so that your units match! Mass of magnesium strip Moles of magnesium used Convert the mass of each magnesium strip into moles using the molar mass. Moles of magnesium Moles of hydrogen produced (n) Use the mole ratio from the balanced chemical equation to convert the moles magnesium...
