Among the given compounds, CH3CH2CH2OH (1-propanol) will have maximum solubility in water.

Reason:
Solubility is based on the principle of 'Like dissolves Like'. Hence, water is a polar solvent, hence it will dissolve polar solvent to maximum extent. Among the listed solutes, CH3CH2CH2OH has maximum polarity.

Further, CH3CH2CH2OH is capable of displaying hydrogen bonding with water, while other compounds will not show hydrogen bonding. With reference to hydrogen bonding, it may be noted that when hydrogen atom is bonded to electronegative elements like O, N and F, it exhibits hydrogen bonding. Due to this, CH3CH2CH2OH will be readily soluble in water.

Correct answers are:

Solids can diffuse in liquids. Think of a sugar cube sitting at the bottom of a cup of tea.
Liquids can diffuse in liquids. Think of a drop of food colouring in water
It is the process of intermingling atoms from one substance into another.

The other answers are incorrect because:

Gas molecules are far apart and diffuse rapidly.
A solid can diffuse into another solid. Pure lead can diffuse into gold, and pure gold can diffuse into lead.

A 32.5 g iron rod, initially at 22.4 ∘C, is submerged into an unknown mass of water at 63.0 ∘C, in an insulated container. The f

Answer:

$m_{H_2O}=39.0g$

Explanation:

Hello,

In this case, is possible to infer that the thermal equilibrium is governed by the following relationship:

$\Delta H_{iron}=-\Delta H_{H_2O}\\m_{iron}Cp_{iron}(T_{eq}-T_{iron})=-m_{H_2O}Cp_{H_2O}(T_{eq}-T_{H_2O})$

Thus, both iron's and water's heat capacities are: 0.444 and 4.18 J/g°C respectively, so one solves for the mass of water as shown below:

$m_{H_2O}=\frac{m_{iron}Cp_{iron}(T_{eq}-T_{iron})}{-Cp_{H_2O}(T_{eq}-T_{H_2O}} \\\\m_{H_2O}=\frac{32.5g*0.444\frac{J}{g^0C}*(59.7-22.4)^0C}{-4.18\frac{J}{g^0C}*(59.7-63.0)^0C} \\\\m_{H_2O}=39.0g$
