I am pretty sure it is white white liquid but if I’m not right I am so sorry
F = G(m1 m2)/(r)^2
Let m1 be the mass of Mars
Let m2 be the mass of Deimos.
Therefore, 6m2 is the mass of Phobos.
We know that G, m1, and m2 are just constants.
Phobos:
Fp = G(m1 * 6m2)/(9000000m)^2 = 7 × 10^(-14) * G m1 m2
Deimos
Fd = G(m1 * m2)/(23000000m)^2 = 2 × 10^(-15) * G m1 m2
Mars exerts a stronger gravitational force on Phobos since Fp > Fd
Answer:
The solution is not ideal.
The relative strengths of the solute-solvent interactions are greater compared to the solute-solute and solvent-solvent interactions
Explanation:
The total vapor pressure is the sum of the partial pressures of water and methanol, and they are calculated by the Raoult´s law equation:
Pₐ = Xₐ Pºₐ, where Pₐ is the partial pressure of component A
Xₐ is the molar fraction of A
P⁰ₐ is the pressure of pure A
So lets calculate the partial pressures of methanol and water and compare them with the given total vapor pressure of solution:
X H2O = 0.312 ⇒ X CH3OH = 1 - 0.312 = 0.688
PH2O = 0.312 x 55.3 torr = 17.3 torr
PCH3OH = 0.688 x 256 torr = 176.1 torr
Ptotal = PH2O + PCH3OH = 17.3 torr + 176.1 torr = 193.4 torr
This pressure is less than the experimental value of 211 torr. So the solution is not ideal. The relative strength of the solute-solvent interactions are greater than the solute-solute and solvent-solvent interactions.
The reason for this is the presence of hydrogen bonding between methanol and water.
I heard of this before I think I know the answers.
1st one, I'm thinking D. Because Turning Liquid into a Solid means like it would take energy out since its freezing.
2nd one, I would choose A
B and C why would they slow down if they were still in a solid. they attracted one another, but they stood still(Didn't move). D is explaining how Liquid turns into a Solid, so this is definitely incorrect. So I would choose A.
I really do hope this helps you out. (Idk about the 1st, but 2nd I think its the answer)
Download the app called Socratic it helps with this
