Transportation Summary
Summary - In lower organisms, there is no transport system as the cells are in touch with the surrounding medium. The transport is by the physical processes like diffusion, osmosis, etc. With the advancement in structure, the organisms have to evolve methods to tr..
Hit and Trial Method or Inspection Method
The symbols and formulae of the reactant and products are written as a skeletal equation. Any elementary gas (O 2 , H 2 , N 2 etc.) appearing on either side of the skeletal equation, is written in the atomic state. The formula containing the maximum number of atoms is selected to begin the..
Balancing Chemical Equations
Balancing of Chemical Equation - A chemical equation should be balanced so as to satisfy the requirements of the law of conservation of mass, as no matter is destroyed or created during a chemical reaction. The two popular methods of balancing are the hit and..
Balancing of Chemical Equations
. Such an equation is called an unbalanced equation or skeleton equation . All chemical reactions need to be balanced because, in a chemical reaction “matter can neither be created nor destroyed”. This means that the total mass of the reactants must be equal to the total mass ..
Balancing Oxidation-Reduction Reactions
There are two very important methods for balancing oxidation-reduction reactions. These are: Oxidation number method Ion-electron meth..
Partial Equation Method
When equations contain many reactants and products they cannot be balanced by the hit and trial method. They are then balanced by the partial equation method. In this method the overall reaction is assumed to take place through two or more simpler ..
Ion-Electron Method
The balancing of a chemical equation by ion-electron method (using half reactions) is done acccording to the following steps: Find the elements whose oxidation numbers are changed. Choose the substance, which acts as an oxidizing agent and one that acts as a reducing agent. ..
Methods to Enforce the Concept of Sustainable Development

I dont even think my school teachers has as much knowledge as this tutors does. Tutor Vista ROCKS.........
My daughter is in 9th grade and I was having a hard time helping her. I am finding TutorVista very helpful. I don't want my daughter to think she knows more than her Mom :-) Thank you all - Megan
We got alot done all the responses were fast the internet was kinda slow but that cant be helped this was a good tutor and they taught everything clearly. - Jenifer
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
