Difference between chemical and physical change?
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
Characteristic of a substance that can be measured or observed without changing the identity of the material?
I believe that you are referring to physical properties. They are observed without changing composition of the substance. Physical properties are more obvious things like colour, shape, etc.
How do chemical and physical properties differ?
chemical properties cannot be determined just by viewing or touching the substance and physical properties can be observed or measured without changing the composition of matter.
How would you convert benzophenone into benzanilide?
Benzophenone can be converted into benzanilide by reacting it with aniline in the presence of a base, such as potassium hydroxide. The reaction proceeds via nucleophilic aromatic substitution, where the aniline replaces the oxygen in benzophenone, forming benzanilide. The product can be isolated and purified by techniques such as recrystallization.
What is the procedure of recrystallisation of benzanilide?
To recrystallize benzanilide, you would first dissolve it in a hot solvent (such as ethanol) until it forms a clear solution. Next, slowly cool the solution to allow crystals to form. Filter the crystals, wash them with a cold solvent to remove impurities, and then allow them to dry to obtain pure benzanilide crystals.
Why ethanol is used in recrystallization of benzanilide?
Ethanol is often used in the recrystallization of benzanilide because it is a good solvent for benzanilide at high temperatures. When the mixture is cooled, benzanilide becomes less soluble in ethanol, leading to the formation of pure crystals as it precipitates out of the solution. Ethanol also helps to minimize impurities in the final crystal structure of benzanilide.
What is the dipole moment of benzanilide?
The dipole moment of benzanilide is approximately zero because the molecule is symmetrical and the dipoles cancel each other out. Benzanilide consists of a benzene ring linked to an aniline group, resulting in opposing dipole moments that effectively cancel each other.

Why benzanilide not soluble in water?
Benzanilide is not soluble in water because it is a nonpolar compound, meaning it does not have any charged or polar groups that can interact with water molecules through hydrogen bonding. Instead, benzanilide's nonpolar nature leads to weak van der Waals interactions with water, resulting in poor solubility.
What are physical properties of a textbook?

What is solubility of benzanilide?
Benzanilide is a white crystalline solid that is moderately soluble in organic solvents such as ethanol and acetone, but it has low solubility in water. Its solubility in water is limited due to its relatively nonpolar structure, which hinders interactions with polar water molecules. Typically, benzanilide's solubility in water is in the range of a few milligrams per liter.

What are physical propeties?
Noticable things are physical properties. Look, appearance, feel, taste, etc. are physical properties. Physical properties can change after a chemical reaction.
