Answer: bubbles form in boiling water
Explanation:
Answer:
liquids, gases, solids
Explanation:
Solids atoms are tightly packed which causes them to have no room and little vibration. Gases have a lot of room which causes them to bounce. And liquids have H2.o which means there atoms are spread very far apart. HOPE THIS HELPED!!
Biphenyl will have a higher R value than the Methyl Orange.
Explanation:
Biphenyl is a aromatic hydrocarbon and it is a nonpolar molecule.
Methyl Orange is a organic compound with a -SO₃⁻Na⁺ polar functional group which will induce a high polarity in the compound.
You may find the chemical structures of both molecules in the attached picture.
Column chromatography, which use as stationary phase silica gel, is a good technique for separation of the Methyl Orange from Biphenyl.
Being a non-polar molecule, Biphenyl will have a higher R value than the Methyl Orange.
To separate them you use a appropriate solvent as eluent, as exemple chloroform, and Biphenyl will elute first from the column and after that, as a separate phase, Methyl Orange will elute thus separating them.

We know that at state 1, we can describe the gas at STP by P1V1=n1RT1
We change the volume, so now there is a second state, state 2 that can be described as
P2V2=n2RT2
We are told that temperatures are constant and since no gas is lost then moles don't change. Hence n1T1=n2T2. So rearrange the equations as follows
P1V1/R=n1T1
P2V2/R=n2T2
Set them equal per my explanation above:
P1V1/R=P2V2/R
Now multiply by R on both sides
P1V1=P2V2
We want to find the pressure at state 2
P1V1/V2=P2
(1 atm)(10L)/(3L) = 3.33 atm = P2
