Prefixes in SI system
The SI units of some of the physical quantities are either too small or too large. To change the order of magnitude, the metric system, which is a decimal system, relates this in powers of ten. These powers are indicated by prefixe..
Chemistry of Salt Formation in Seawater
The chemistry of seawater is very complex. Many multistep equilibrium operate simultaneously. A sequence of chemical reactions following the weathering of the igneous rock is given below: Igneous rocks consist of aluminosilicates of calcium, potassium, sodium etc. Rainwater containing som..

: With the same number of carbon atoms, it is possible to have different arrangement of atoms and therefore entirely different compounds. With five carbon atoms, it is possible to have three isomers; with ten carbon atoms it is possible to have 75 isomers and with 60 carbon atoms over..
: With the same number of carbon atoms, it is possible to have different arrangement of atoms and therefore entirely different compounds. With five carbon atoms, it is possible to have three isomers; with ten carbon atoms it is possible to have 75 isomers and with 60 carbon atoms over..Conclusion
Rate of reaction usually doubles when the temperature is raised by ten degrees near the normal temperature because the rate constant is dependent on temperature. The temperature dependency of rate constant is mathematically expressed by the Arrhenius equation. Arrhenius equation is ..
Representative or Main Group Elements
Representative or Main Group Elements - These consist of all 's' and 'p' block elements excluding the noble gases (group 18 elements). The chemical properties of the representative elements are determined by the number of valence electrons in their atoms. The number of valence electrons belonging t..
Surface Chemistry Conclusion
>Catalysis involves reactions where catalysts are used. Catalysts are used to accelerate the rate of reaction. Catalysts accelerate the rate of reaction by providing an alternate reaction pathway in which the activation energy is lower. Homogenous catalysis involves catalysts which are of the same ..

Tutor Vista perceived the math apps well and I enjoyed getting to work with Tutor Vista - Savannah
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
I have experienced very innovative way of learning, I joined online tutoring at Tutorvista few months back when I was in grade 10, I scored really well in grade 10 and ny parents were really happy.
Looking for More Help!
