A student is using a microscope to observe samples taken from pond water. She notices something that she thinks may be a living thing. Which feature would BEST support that the unknown sample is a living thing? A.
Since all living things are green, observing an unknown sample is green will provide evidence that it is a living thing.

B.
Since all living things are made up of cells observing a cell in the unknown sample will provide the evidence that it is a living thing.

C.
Since all living things make bubbles, observing an unknown sample that is making bubbles will provide the evidence that it is a living thing.

D.
Since all living things move, observing something move in the unknown sample will provide the evidence that it is a living thing.

You have to rewrite the ideal gas law in terms of n. (n=PV/RT)
you are given V=0.53L, T=329K, and P=3.0atm, R is a constant so you already know that R=0.08206atmL/molK.
n=(3.0atmx0.53L)/(0.08206atmL/molKx329K)
n=0.0589mol gas
