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.
The density of the object is 0.467 36 g/cm³.
The mass of the object is 389.27 g.
The volume of the object is 832.92 cm³.
Density = mass/volume = 389.27 g/832.92 cm³ = 0.467 36 g/cm³
This would be the downward movement of water. It begins flowing and continues in a downward movement moving throughout,
Potassium nitrate does not have a net ionic equation. It is because potassium nitrate is not soluble and does not produce precipitates. The net ionic reaction is going to be Zn2+ + S2- -> ZnS(s). Zinc sulfide precipitates in the net ionic reaction.
It is c because I did it already
