Answer:

1.For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

2.Energy from hot water molecules makes solids more soluble. In hot water, molecules are moving around more, so there are more collisions between the water molecules and a solid. A solvent is a substance that can dissolve other substances – water is a good solvent.

3.For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

Answer:

how does temperature affect the solubility of a liquid? = For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions

why do you think liquids are more soluble in warmer solvents? = Energy from hot water molecules makes solids more soluble. In hot water, molecules are moving around more, so there are more collisions between the water molecules and a solid. A solvent is a substance that can dissolve other substances – water is a good solvent.

As the temperature of a solution increases, the average kinetic energy of the solvent molecules increases. This increase in kinetic energy allows the solvent molecules more effectively to separate the solute molecules that are held together by intermolecular attractions.

An aqueous solution of 1.29 M ethanol, CH3CH2OH, has a density of 0.988 g/mL. The percent by mass of CH3CH2OH in the solution is

anzhelika [568]

Answer:

Explanation:

Hello, for this case, we assume that the volume of the solution is 1L, thus, the mass is given by using the density as follows:

$m_{solution}=1L*\frac{1000 mL}{1L}*\frac{0.988g}{1mL} =988g$

Now, the mass of the ethanol:

$m_{C_2H_5OH}=(1.29molC_2H_5OH/L*1L)*\frac{46gC_2H_5OH}{1molC_2H_5OH} \\m_{C_2H_5OH}=59.34g$

Finally, the by mass percent is:

$m/m=\frac{59.34g}{988g}*100\\$ %

%m=6%

Best regards.

Ethyl alcohol (ch3ch2oh) is/is not soluble in water. 1. is; all organic molecules are soluble in water. 2. is; ethyl alcohol exh

nata0808 [166]

Answer:
Ethyl alcohol is soluble in water because <span>ethyl alcohol exhibits dipole-dipole and h-bonding interactions with water.

Explanation:
Ethyl alcohol and water are miscible in each other because both are polar in nature and "Like dissolves Like".
The bond between oxygen and hydrogen atoms, both in alcohol and water are polar in nature and results in intermolecular hydrogen bond interactions between them as hydrogen bonding results when hydrogen atom in one molecule directly attached to highly electronegative atoms like fluorine, oxygen and nitrogen forms interaction with higly electronegative atom of neighbor atom.</span>
