Answer:
The balloon filled with Helium will effuse more quickly.
Explanation:
Step 1: Data given
Balloon 1: Has a volume 4.3L , a pressure of 1.68 atm and is filled with 1.21g of Helium
Balloon 2: Has also a volume of 4.3 L and a pressure of 1.68 atm but is filled with 39.63 grams of Xenon
Molar mass of He = 4g/mol
Molar mass of Xe = 131.3 g/mol
Since He is lighter than Xe, the effusion rate for He will be larger than that for Xe, which means the time of effusion for He will be smaller than that for Xe.
The balloon filled with Helium will effuse more quickly.
You would use the density difference to separate the sand, evaporate the water out (the water vapor will cool back to water if collected). Then use a magnet to get the iron fillings out of the salt.
Answer:
A fire extinguisher
Explanation:
A lab station usually contains equipment for the people working at the station to use. However, most rooms will only have one fire extinguisher for the whole room meaning it would most likely be located somewhere that is easy to access by all and not just a singular lab station.
