What else can I help you with?
What molecules would you expect to dissolve in water polar covalent molecules inoic molecules nonpolar convalent molecules?
ionic molecules dissolve the most. but some polar covalent molecules also do dissolve in water.
What solvents change water's boiling point?
Any solvent can; the more ions it dissipates into, the more it will change the boiling point (in general). You shouldn't expect a very large change, however. Pressure tends to affect boiling point more than solvents.
Why would you not expect to find a solution with a solid solvent?
A solid solvent typically lacks the mobility required for solvation, which is essential for dissolving solutes. In a solution, solute particles must interact with solvent molecules, and solids do not have the fluidity to facilitate these interactions effectively. Additionally, solid solvents do not provide the necessary molecular interactions to break down solute structures, leading to the expectation that solutions would not form. Thus, solid solvents are generally not conducive to creating solutions.
Why would you expect the tail to be nonpolar?
The tail of a molecule, particularly in the context of lipids, is expected to be nonpolar because it typically consists of long hydrocarbon chains. These chains are made up of carbon and hydrogen atoms, which share electrons relatively evenly, resulting in a lack of significant charge separation. This nonpolar nature makes the tail hydrophobic, allowing it to avoid interactions with water and instead aggregate with other nonpolar substances. Such properties are crucial for the formation of cellular membranes, where nonpolar tails shield themselves from the aqueous environment.
What cannot be dissolved by water?
Substances that cannot be dissolved by water are typically nonpolar molecules, such as oils, fats, and waxes. These substances do not have charged regions that can interact with the polar water molecules, making them insoluble. Additionally, some ionic compounds with very low solubility in water, like silver chloride or lead(II) sulfide, are considered insoluble in water.

What molecules would you expect to dissolve in water polar covalent molecules ionic molecules nonpolar covalent molecules?
Polar covalent molecules are likely to dissolve in water because they have partial positive and negative charges that can interact with water molecules through dipole-dipole interactions. Ionic molecules also dissolve in water as the positive and negative ions are attracted to the polar water molecules. Nonpolar covalent molecules do not dissolve well in water because they lack partial charges that can interact with water molecules.
You expect NaCl to dissolve in fat?
no

Why should you not expect the halides ions to dissolve in mineral oil?
halide ions strongly interact with the counter-ions. However, mineral oil is non-polar. To dissolve the halide ions (and the counter-ions) into mineral oil would drastically raise system energy. Thus it does not work. More simply, halide ions have a charge and won't easily dissolve in non-polar substances, since like-dissolves-like.

Carbohydrates and lipids are very large organic molecules Which two bonds do you expect to find most in these molecules?
ANSWER: nonpolar cavalent bonds and polar covalent bonds

Benzoic acid is non-water soluble?
From the structure of benzoic acid, we can see that the phenyl substituent makes of most of the molecule, so we should expect it to be nonpolar with respect to water. However, if another molecule were to deprotonate the benzoic acid (ie. with a base like NaOCH3), its conjugate base -- which by the way is negatively charged -- will easily dissolve in water because it can form favorable interactions with water molecules.
Do you expect distribution of the solutes on each side of each membrane to change over time?
Yes, the distribution of solutes across each membrane is expected to change over time due to processes such as diffusion and osmosis. Solutes will move from areas of higher concentration to areas of lower concentration until equilibrium is reached. Additionally, active transport mechanisms may further alter solute distribution by moving substances against their concentration gradients. Thus, the solute distribution is dynamic and influenced by various factors.
How does you expect an ionic component to behave when mobile phase is a relatively nonpolar solvent such as acetone?
In a relatively nonpolar solvent like acetone, an ionic component is expected to exhibit low solubility due to the solvent's inability to stabilize the charged particles. Consequently, the ionic species may remain largely undissociated, leading to reduced mobility in the mobile phase. This could result in poor separation efficiency during chromatographic processes. Overall, the ionic component is likely to be retained longer on the stationary phase compared to nonpolar compounds.
