Solution : In reaction with Sodium Carbonate, Carboxylic acids produce carbon dioxide gas which turns lime water milky whereas alcohols do not give this reaction. This experiment can be used to distinguish alcohol and carboxylic acid. Some example in table :

Solution : Agitation is necessary to clean clothes as agitation aid soap micelles to trap the oil, grease or any other impurities that have to be removed. When they are being beaten or agitated, the particles are removed from the clothes’ surfaces and go into the water, thus cleaning the clothes.

Solution: Carbon can neither lose 4 electrons nor do gain four electrons as these processes make the system unstable due to the requirement of extra energy. Therefore CH3Cl completes its octet configuration by sharing its 4 electrons with carbon atoms or with atoms of other elements. Hence the bonding that exists in CH3Cl is covalent. …

Solution:

Solution : Many impurities and dirt are mixed in the water, and most of all the dirt does not dissolve in the water. Soap molecules are a combination of salts such as sodium or potassium. The molecules are of a long chain of salt of fatty acids. So, when the carbon chain is dissolved in …
