 Podar International school,Vadodara Summer vacation Home work  General instructions for Summer Home Assignment for all subject. GENERAL NOTE: Kindly submit all your work of all subjects to respective subject teacher as and when  it gets completed through mail.  Create your assignment in your own style with new ideas as per given instruction. The aim for home assignment only for learning. So no need to go out for any material or anything to purchase. Use handy material which is already available at home. Use waste material/scrap /best out of waste /reusable things as per your use. Notebook work can be completed in any notebook that you have at home (used one or new one or papers). You may keep one single notebook for all assignments. No need to go out to buy anything pertaining to your assignment. English Prepare speech on (Any one topic) and record your video for the same 1. Man’s use of fossil fuels – coal, oil, and natural gas – together with deforestation has inc...

Chemistry class - Topic taught as on 21/4/21

Expression of Nernst Equation Nernst equation is an equation relating the capacity of an atom/ion to take up one or more electrons (reduction potential) measured at any conditions to that measured at standard conditions (standard reduction potentials) of 298K and one molar or one atmospheric pressure. Nernst Equation for Single Electrode Potential Ecell = E0 – [RT/nF] ln Q Where, Ecell = cell potential of the cell E0 = cell potential under standard conditions R = universal gas constant T = temperature n = number of electrons transferred in the redox reaction F = Faraday constant Q = reaction quotient The calculation of single electrode reduction potential (Ered) from the standard single electrode reduction potential (E°red) for an atom/ion is given by the Nernst equation. For a reduction reaction, Nernst equation for a single electrode reduction potential for a reduction reaction Mn+ + ne– → nM is; Ered = EMn+/M = EoMn+/M – [2.303RT/nF] log [1/[Mn+]] Where, R is the ...

Chemistry - Topic taught 20 April

Electrochemistry  is the branch of chemistry which deals with the relationship between electrical energy and chemical energy and inter-conversion of one form into another. 2. An electrochemical cell  consists of two metallic electrodes dipped in electrolytic solutions. The cells are of two types: (a) Electrolytic cells (b) Galvanic cells 3. A galvanic cell  consists of two half cells. Each half cell contains an electrolytic solution and a metallic electrode.The electrode at which- oxidation takes place is called an anode and the electrode at which reduction takes place is called the cathode. The half-cells are separated from each other by means of a porous pot or a salt bridge. What is Salt Bridge? A salt bridge is a device used in an electrochemical cell for connecting its oxidation and reduction half cells wherein a weak electrolyte is used. In other words, a salt bridge is a junction that connects the anodic and cathodic compartments in a cell or electrolytic solution....
