VLD [36.1K]

Fatty acids are composed of hydrocarbon chains and a carboxyl group.

<h3>What are Fatty acids ?</h3>

Fatty acids are the building blocks of the fat in our bodies and in the food we eat.

During digestion, the body breaks down fats into fatty acids, which can then be absorbed into the blood.

Fatty acid molecules are usually joined together in groups of three, forming a molecule called a triglyceride.

Generally, a fatty acid consists of a straight chain of an even number of carbon atoms, with hydrogen atoms along the length of the chain and at one end of the chain and a carboxyl group (―COOH) at the other end.

It is that carboxyl group that makes it an acid (carboxylic acid).

ra1l [238]

Answer : The incorrect option is, The most of the mass of the atom comes from the electron cloud.

Explanation :

There are three basic particles of an atom which are neutrons, protons and electrons.

The nucleus which is present in the center of an atom that contains the neutrons and the protons. The protons are positively charged and neutrons has no charge.

The outer region of an atom contains the electrons and the electrons are negatively charged.

As per given options, the statement which is the most of the mass of the atom comes from the electron cloud is incorrect statement because the most of the mass comes from the nucleus in which protons and neutrons are present.

Describe the reaction below by listing the
rjkz [21]

Answer:

The covalent bond in Cl₂ is break and combine with sodium to form NaCl through ionic bond.

Explanation:

Chemical equation:

Na  +  Cl₂    →   NaCl

Balanced chemical equation:

2Na  +  Cl₂    →   2NaCl

The given reaction indicate the formation of sodium chloride.

Sodium chloride is an ionic compound. It is formed by the reaction of chlorine and sodium. The type of bond in Cl₂ is covalent. Both chlorine atoms are tightly held together through sharing of electrons. When sodium chloride is formed the covalent between the chlorine atoms are break and it react with sodium . The chlorine toms thus gain the one electron from the sodium atom and became negative ion while sodium by losing its one valance electrons became positive ions. The strong electrostatic forces are develop between them and ionic bond is formed.
