Answer:the answer would be a because that's what it would talk about and is the correct answer
Explanation:yes it is correct just answer it trust me
Answer:
Option C (a higher; the same) is the appropriate response.
Explanation:
Given:
Temperature,
T = 300 K (both
and
)
As we know,
Average speed of a molecule,
⇒ 
Thus, the average speed of
will be lower as its molar mass is greater than
.
Now,
⇒
(not depend on molar mass)
Hence, it will be the same.
The other three alternatives aren't connected to the scenario given. So the above is the correct answer.
Concentration is found by dividing the mass of solute by the volume of the solution. C = 4.2g/0.25 L. C= 16.8 g/L
The chemical with the lowest point is helium
