Amides are typically not soluble in cold hydrochloric acid due to their non-polar nature. The acidic conditions of hydrochloric acid can protonate the amide bond, making it less soluble in water. Heating may be required to promote solubility by breaking down the amide bonds.
Beeswax is a nonpolar substance and water is a polar solvent, so they are not compatible. Ethanol, being able to dissolve both polar and nonpolar substances, can dissolve a small amount of beeswax. Chloroform, being nonpolar like beeswax, allows for better solubility due to similar intermolecular forces.
Chloroform (CHCl3) is more soluble in water than carbon tetrachloride (CCl4) because chloroform has a dipole moment, allowing it to form hydrogen bonds with water molecules. Carbon tetrachloride is nonpolar and lacks the ability to form hydrogen bonds with water, making it less soluble.
No, carbon dioxide is more soluble in water than oxygen. This is why carbon dioxide can readily dissolve in water to form carbonic acid, whereas oxygen is less soluble and does not react as readily with water.
Iodine is not soluble in water because iodine is nonpolar and water is polar. According to the "Like dissolve like" expression, nonpolar substances are soluble with nonpolar substances and polar substances are soluble with polar substances, but nonpolar substances are not soluble with polar substances.

As wood is made of many, many chemical substances, some components may be more soluble than others. For example, some ionic substances containing sodium and potassium ions would be completely soluble, while, for example, some starches would be considerably less soluble.
Sugars with increasing carbon units tends to be less soluble in water like polysaccharides.
I think oil will be less soluble in water at elevated temperatures.
Amides are typically not soluble in cold hydrochloric acid due to their non-polar nature. The acidic conditions of hydrochloric acid can protonate the amide bond, making it less soluble in water. Heating may be required to promote solubility by breaking down the amide bonds.
The solubility of a substance in water is usually determined by the polarity of the substance and water molecules. Polar substances tend to dissolve in water because they can form favorable interactions with water molecules. Nonpolar substances, on the other hand, are less soluble in water because they cannot form strong interactions with water. Temperature, pressure, and presence of other solutes can also affect solubility.
Excess concentration of fat-soluble vitamins can lead to toxicity because they are stored in the body's fat tissues and can accumulate over time. In contrast, excess water-soluble vitamins are easily excreted from the body through urine, making toxicity less likely but can still cause adverse effects at very high levels.

It has very less water solubility
Beeswax is a nonpolar substance and water is a polar solvent, so they are not compatible. Ethanol, being able to dissolve both polar and nonpolar substances, can dissolve a small amount of beeswax. Chloroform, being nonpolar like beeswax, allows for better solubility due to similar intermolecular forces.
No, salt is more soluble in hot water than in cool water. Hot water molecules have more energy, creating more space between them for salt molecules to dissolve. This allows for more salt to dissolve in hot water compared to cool water.
