what is neutralization reaction? with example.

A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water. The neutralization of a strong acid and strong base has a pH equal to 7.  For example when HCl (Hydrochloric acid), a strong acid, reacts with NaOH, a strong base, the resulting salt is sodium chloride and water.

What is homologous series?

A homologous series is a group of organic compounds having similar structures and similar chemical properties in which the successive compounds differ by (CH2).

Meaning of Homologous Series

A homologous series refers to a series of carbon compounds which have a different number of carbon atoms. However, they contain the same functional group.

In this series, a group of compounds share similar basic chemical makeup. Also, in such a series, the compounds show a difference in the number of iterations of a certain aspect of their structure.

Properties of Homologous Series 

Repeating unit is the most important characteristic of a homologous series. An example can be the alkaline group which consists of the CH2 repeating unit.

What this means is that the compounds are identical with the notable exception of the number of CH2 units existing in the compound.

Organic compounds certainly have functional groups. Moreover, these groups define the fundamental and basic properties of the compound.

Most noteworthy, every compound in the homologous series is in the same functional group. However, these compounds have different numbers of repeating units.

Question 1. What is the general formula for aldehydes?

Answer : Aldehydes contain an alkyl group or a hydrogen group that contains a benzene ring in addition to one hydrogen atom that is attached to the carbonyl group. Aldehyde has the generic formula CnH2n+1CHO or CnH2nO because alkene has the universal formula Cn H2n+1.

Question 2 : What does it indicate when a series is homologous to another?

Answer : A group of hydrocarbons that share the same general formula and exhibit chemical properties that are comparable to one another is called a homologous series. There are three distinct hydrocarbon series that is: alkanes, alkenes, and cycloalkanes. Only hydrogen and carbon make up hydrocarbons. A sequence of carbon compounds that share an overall structure but differ in the number of carbon atoms that they contain is known as a homologous series. 

On the other hand, both of them have the same functional group. A collection of chemicals in this series have a fundamental chemical composition that is comparable to one another.

Give some examples of rancidity and some precautions also.

example of rancidity Some examples of rancidity are - Food when exposed to atmospheric air for a long duration becomes rancid. Butter changes its taste and smell when kept in an open atmosphere for a longer duration. Some precaution to prevent rancidity : Food should be kept in sealed containers. Food that needs to be refrigerated. Foods containing fat and oil can be packaged in nitrogen gas to prevent rancidity. To avoid rancidity, food should be stored away from light. Antioxidants can be added to food.

Class -IX : Atoms and Molecules

Law of Chemical Combination Given by Lavoisier and Joseph L. Proust as follows: 1. Law of conservation of mass Mass can neither be created nor destroyed in a chemical reaction. e.g. A + B → C + D  Reactants → Products, Mass of reactants = Mass of products 2. Law of constant proportion In a chemical substance the elements are always present in definite proportions by mass. e.g.,  in water, the ratio of the mass of hydrogen to the mass of oxygen is always 1 : 8 respectively. These laws lacked explanation. Hence, John Dalton gave his theory about the matter. He said that the smallest particle of matter is called ‘atom’. Dalton’s Atomic Theory ·        Every matter is made up of very small or tiny particles called atoms. ·        Atoms are not divisible and cannot be created or destroyed in a chemical reaction. ·        All atoms of a given element are same in size, mass and chemical properties. ·        Atoms of different elements are different in size, mass and
