For eg. H2 + O2 → H2O.... Here no.of atoms in lhs...for hydrogen is 2 and oxygen is also 2....but in RHS no of atom in hydrogen is 2 but in oxygen it is only 1..so by balancing it become.. 2H2+O2→ 2H2O...... In this no of atom in both side us equal... In LHS- H- 4, O-2...SAME IN RHS...H-4, O-2

To balance a chemical equation, start by writing down the number of atoms in each element, which is listed in the subscript next to each atom. Then, add coefficients to the atoms on each side of the equation to balance them with the same atoms on the other side

What is the difference between organic acid and weak acid

Posted by Posa Sai 5 years, 8 months ago

CBSE > Class 10 > Science

Meghna Thapar 5 years, 6 months ago

In general, organic acids are weak acids and do not dissociate completely in water, whereas the strong mineral acids do. Lower molecular mass organic acids such as formic and lactic acids are miscible in water, but higher molecular mass organic acids, such as benzoic acid, are insoluble in molecular (neutral) form. A great way to identify whether or not you are looking at an organic acid is to find the carboxylic acid functional group, RCOOH. A weak acid is one that does not dissociate fully in water. ... Lactic acid, acetic acid, propionic acid, formic acid, butyric acid, valeric acid, oxalic acid, lactic acid, magic acid, citric acid, benzoic acid.

Define the term elrctrical resistivity of material

Posted by Sabita Sha 5 years, 8 months ago

CBSE > Class 10 > Science

2 answers

Yogita Ingle 5 years, 8 months ago

Electrical resistivity is the reciprocal of electrical conductivity. It is the measure of the ability of a material to oppose the flow of current.

Metals are good conductors of electricity. Hence, they have low resistivity.
The insulators like rubber, glass, graphite, plastics, etc. have very high resistivity when compared to the metallic conductors.
The third type is the semiconductor which comes in between the conductors and insulators. Their resistivity decreases with the increase in temperature and is also affected by the presence of impurities in them.

Electrical resistivity, represented by the Greek letter ρ (rho), is a measure of how strongly a material opposes the flow of electric current.

How the fats of our body digested? Where this process are happen?

Posted by Aditya Kumar 5 years, 8 months ago

CBSE > Class 10 > Science

1 answers

Yogita Ingle 5 years, 8 months ago

Fats are present in the form of large globules in the small intestine. The small intestine receives the secretions from the liver and the pancreas. The bile salts (from the liver) break down the large fat globules into smaller globules so that the pancreatic enzyme lipase can easily act on them. This is referred to as emulsification of fats. This process takes place in the small intestine.

Respiration is an exothermic reaction

Yogita Ingle 5 years, 8 months ago

There are two types of respiration:

Aerobic respiration

It is a type of cellular respiration that takes place in the presence of oxygen to produce energy. It is a continuous process that takes place within the cells of animals and plants. This process can be explained with the help of the chemical equation:

<center>Glucose(C₆H₁₂O₆) + Oxygen(6O₂) → Carbon dioxide(6CO₂) + Water(6H₂O)+ Energy (ATP)</center>

Anaerobic respiration

It is a type of cellular respiration that takes place in the absence of oxygen to produce energy. The chemical equation for anaerobic respiration is

<center>Glucose(C₆H₁₂O₆) → Alcohol 2(C₂H₅O H) + Carbon dioxide 2(CO₂) + Energy (ATP )</center>
