Neutralization Reaction Definition Class 10 Science A neutralization reaction occurs when an acid and a base react together. As acids and bases react, salt and water are produced as byproducts. Energy is also created throughout the process. The general equation for the neutralizing reaction is as follows: Acid + Base → Salt + Water Examples of Neutralization Reactions Examples of neutralization reactions are given below: 1. Sodium chloride and water are made from a combination of sodium hydroxide and hydrochloric acid. NaOH + HCl → NaCl + H2O 2. In the case of indigestion, milk of magnesia, a base, is administered as an antacid to neutralize the excess acid created in the stomach. Mg(OH)2 + 2HCl → MgCl2 + 2H2O Acids, Bases, and Ions When an acid dissolves in water, it creates positive hydrogen ions (H+) and negative nonmetal ions. (Ions get charged atoms that have lost or gained electrons.) An example of an acid is hydrochloric acid (HCl). HCl creates positive hydrogen ions and negativ

English Worksheet Exercise The Sentence A sentence is a logical combination of words. A sentence must always start with a capital letter and end with a period. Children in second grade should practise understanding who to use to construct sentences. Is it making sense to say that the city of Delhi is big?

Erosion of Soil The erosion of topsoil is referred to as erosion. Deforestation, overgrazing, excessive use of fertilisers or pesticides, precipitation flow, landslides, and floods are all possible causes of erosion. What are the soil conservation methods? Mulching - Mulching aids in the retention of moisture in the soil. Mulching is the practise of covering undeveloped area with organic debris such as straw. Contour Barriers — Contour barriers aid in the prevention of rain-induced erosion. Stone, grass, or dirt connected to the contour forms the contour barrier. To store water, a trench has been dug in front of the dam. Dams, such as rock dams , can impede the flow of water. As a result, rocks are arranged to create a dam. Dams like these impede water flow. As a result, dirt and soil are not lost. Terrace Cultivation : In steep places, terrace cultivation is utilised to decrease erosion caused by water flow. To maintain a flat surface for growing crops, the plots are built in terrac

Equivalent Fraction Class 7 Maths When fractions are reduced to their simplest forms, equivalent fractions have the same value in their numerators and denominators . Example to convert a fraction into its simplest form To reduce a fraction to its most basic form, divide both the numerator and the denominator by a common number. Repeat the process until no single number can divide both the numerator and the denominator. Consider the fraction 2/4 as an example. Both the numerator and denominator can be divided by two, as we can see. As a result, we divide 2 and 4 by 2 and substitute the quotients of each division for the numerator and denominator. Because 2 divided by 2 yields a quotient of 1, 2 is replaced with 1. Similarly, the number 4 is replaced with the number 2 since 4 divided by 2 yields a quotient of 2. As a result, the most basic version of 2/4 is 1/2. Fraction Exercise for practice I. Fill in the blank to make the fractions equivalent: 24/__ = 4/1 220/__ = 20/11 20/40 = ___/2

Uses of coal tar - Class 8 Science Notes Coal tar is a thick black liquid produced as a by-product of coal gas and coke manufacture. It contains benzene, naphthalene, phenols, and aniline, among other biochemicals. It's employed in both medicinal and industrial settings. Itching, scaling, and skin problems can all be treated with coal tar. It's used to treat dandruff and lice, and in medicated shampoos and soaps. Analgesic characteristics can be found in phenolic coal tars. Pavements, highways, and parking lot seal-coat products all use coal tar to protect and beautify them. Coal tar is a flammable substance. As a result, it is used for heating. Coal tar is one of the binders used in the graphite industry to make green blocks. Construction paints, synthetic dyes, and photographic materials all include coal tar.

Difference between Fertilizers and Manure  It is made by depositing plant and animal wastes in pits in an open area. It is an organic compound formed by the breakdown of plant or animal faeces. Because it is probably insoluble in water, it is slowly absorbed by the soil and plants. It provides fewer plant nutrients than fertilisers. It enriches the soil with humus. It is not harmful to the soil and, in the long term, enhances soil quality. It is cost-effective since it may be simply made from decaying plant and animal waste. It is created in factories by a chemical process. It is a synthetic or industrially-produced substance that contains plant nutrients. It dissolves easily in water and is promptly absorbed by the soil and plants. It contains more plant nutrients than manure. It does not add humus to the soil. Excessive fertiliser application can degrade soil quality and damage soil organisms. It is expensive because it is manufactured in factories by machines. Tag - online classes f

Short Essay on Pollution for Kids The introduction of any impure substance into the environment, whether in the form of a solid, liquid, or gas, is referred to as pollution. Pollution may contaminate the air, water, and land, resulting in a filthy environment. Chemical particles harm the environment as well. Honking and excessively loud sounds contribute to noise pollution. When artificial fertilisers are mixed with the soil, it results in land pollution. Garbage disposal in open areas pollutes the environment and spreads a number of diseases. Pollution has a negative impact on humans, animals, birds, and the environment. Pollution of the water is caused by the removal of dirty particles from factories. Pollution is caused by improper sewage management, which can be avoided by covering drainage lines. Groundwater is contaminated by metals such as arsenic and mercury. Click for know more Pollution Tag -  online classes for school students, pollution essay, short essay on pollution
