Explanation:
The given data is as follows.
No. of moles = 
, V = ?
T = 20.2 + 273 K = 293.2 K, P = 
= 1.046 atm, R = 
Calculate the volume using ideal gas equation as follows.
P V = n R T
V = 
= 
= 
L
Thus, we can conclude that volume of the gas is L.
Answer:
13: d
14: d
Explanation:
Filteration is useful when the things you are trying to separate are in different states - i.e an insoluble solid from a liquid.
Homogeneous mixtures are made up of substances in the same state (e.g multiple gases in air), so couldn't easily be separated in filtration.
Solutions have solutes dissolved in them, so they could also not be separated by filtration (e.g salt water or alcohol solution).
Elements are made up of one thing, and depending on the element it would depend on how you separated it. You could have two gases, like hydrogen and helium, which would be hard to separate by filtration!
That leaves heterogeneous mixtures, which are in different states to each other, so this would be an appropriate way to separate them.
Hope this helps! Let me know if you have any questions :)
N2(g) +
3H2(g)<==>2NH3(g) + energy, the changes that occur when the temperature
of this system is decreased is that concentration of H2(g) decreases and the
concentration of NH3(g) increases. The answer is number 4. The rest of
the choices do not answer the question above.
Collect the salt water and put it in something where it can boil under fire or any other heat source capable to bring the water to boiling temperature. You can consume the collected water safely , but wait for its temperature to fall, except if you need it to be hot.
