Answer:
Option C. Electrons are shared between two atoms
Explanation:
Covalent bonding is a type of bonding which exist between two non metals.
In this bonding, electrons are shared between the two atoms involved in order to attain a stable octet configuration.
This can be seen when hydrogen atom combine with chlorine atom to form hydrogen chloride as shown below:
H + Cl —> HCl
Hydrogen has 1 electron in it's outmost shell and it requires 1 electron to attain a stable configuration.
Chlorine has 7 electrons in it's outmost shell and requires 1 electron to attain a stable configuration.
During bonding, both hydrogen and chlorine will contribute 1 electron each to form bond, thereby attaining a stable configuration. The bond formed in this case is called covalent bond as both atoms involved shared electron to attain a stable configuration.
Answer: Soaps are sodium or potassium fatty acids salts, produced from the hydrolysis of fats in a chemical reaction called saponification. Each soap molecule has a long hydrocarbon chain, sometimes called its 'tail', with a carboxylate 'head'.
Explanation: Saponification is an exothermic chemical reaction—which means that it gives off heat—that occurs when fats or oils (fatty acids) come into contact with lye, a base. In this reaction, the triglyceride units of fats react with sodium hydroxide or potassium hydroxide and are converted to soap and glycerol.
