Answer : This is not an ideal mixture.
Explanation :
Using Raoult's law :
where,
= total vapor pressure of mixture
= vapor pressure of pure methanol = 256 torr
= vapor pressure of pure water = 55.3 torr
= mole fraction of water = 0.312
= mole fraction of methanol = 1 - 0.312 = 0.688
Now put all the given values in the above formula, we get:
From this we conclude that the total vapor pressure of mixture is less than the total given vapor pressure of 211 torr. That means, the interactions between the methanol and water would be weaker than those between the individual substances. So, this is not an ideal mixture.
Hence, this is not an ideal mixture.
Answer: The number of energy levels increases as you move down a group as the number of electrons increases. Each subsequent energy level is further from the nucleus than the last. Therefore, the atomic radius increases as the group and energy levels increase.

BARIUM HYDROXIDE IS THE COMPOUND
<span>The shininess of an element is also referred to as "metallic luster." The element that is most likely to have a metallic luster is B. rhodium.
Arsenic has a dull luster, chlorine and hydrogen are gases so they don't have luster.
