specific density

Let us learn about specific density

density is defined as its weight per unit volume. The density of a substance is the reciprocator of its specific volume, a representation commonly victimized in thermodynamics.


Density of substance = D = M/v

The density of a substance is its weight per unit volume

corrosion of iron

Let us learn about corrosion of iron

Iron and different forms of iron are highly susceptible to chemical reactions and their protection from rust costs billions of money annually across the world. Corrosion under atmospheric conditions is extremely complex and the outcome of corrosion is commonly known as ‘rust’. Water & Oxygen gas must be present for Iron to rust. There many metals which react with oxygen, as a glance at the Standard Reduction Potential table will show. With the notable exceptions of silver & gold, most common metals will form spontaneous redox couples with oxygen.

free online tutoring

Hi Friends!!!

How many of you like free online tutoring and why?

Online tutoring refers to the deliver of tutoring within an online realistic surround or networked environs where teachers and learners are distributed by reading and character.


Guidance held on the computer, often using multi-media devices such as webcams, video, audio and interactive materials.


This saves time of student. It is more flexible, service will be available 24/7 any time any day. Student get immediate feedback with report card. There many websites which provides free online tutoring.

list of natural resources

Hi Friends!!!

In our previous blog we learned about "Types of natural resources" . Now let find list of natural resources.

Natural resources become course within environments that survive relatively undisturbed by mankind, in an uncolored cast.


list of natural resources.

1. Solar energy
2. Wind power
3.
Hydropower
4.
Geothermal power
5. Soil
6. Animals
7. Forest and so on

In our next blog we shall learn about diseases caused by viruses I hope the above explanation was useful.Keep reading and leave your comments.

basicity

Let us learn about basicity

A inferior method for evaluating the magnitude of bases is to story the acidities of the united acids of the bases (these conjugate acids are oft "onium" cations). The resulting pKa's are proportional to the immoral magnitude of the substructure.

A reusable concept is: pKa + pKb = 14.

Amines are reasoned to be the alkyl- or aryl computation of ammonia (NH3). Amines can be classified on the cornerstone of the size of alkyl or aryl groups substituted for the hydrogen

Or

in new line, on the magnitude of replacement at the nitrogen speck of ammonia.Commonly, aryl substituted liquid are titled aryl amines or aromatic amines. Among radical substituted liquid (group amines), we make the succeeding categories:

a) Substitute amines

b) Tertiary amines

c) Primary amines

Polymers


what are polymers ?

Polymers are molecules which exist of a daylong, continuation formation of small units called monomers. Polymers hit the maximal molecular metric among any molecules, and may exist of zillions of atoms. Frail DNA is a polymer with over 20 1000000000 essential atoms. Proteins, or the polymers of amino acids, and some another molecules that get up brio are polymers. Polymers are the maximal and most diverse category of renowned molecules. They regularize include plastics.
