half equation is normally used in electrolysis actually we divide our electrolytic cell in two half cell reaction and termed as anodic and cathodi compartment and their equations r termed as half cell equation please elaborate your question thanx

sorry party i m late to read ur messages else isurely have given answer to your questions well how was your paper was that bad or you pass through it easily cya

hello you r too fast in order to understand mole u pick the wrong concept mole is actually a molecular mass or atomic mass of a molecule or an atom expressed in grams and 6.02x10^23 is the no. of molecules or no. of atoms per mole for mole u can find out from the equation of disociation of NaHCO3 it would be three moles of oxygen now no of moles=mass/mol mass no of molecules = Avogadros no.(6.02x10^3)x mass of substance/molecular mass no of atoms = Avogadro's n0x mass of sub/atomic mass simple now i think your problem is solved u can ask more freely:-)

i agree with bignose first you must try yourself helping doesnot mean to make you idle dont make yourself sluggish by jamming your brain try it on your own and show that you have done something dont worry if u cant we will hellp you solve it out surely dont worry:-)

hello to all there lovely biologists i dont have much knowledge about our ancestors neither i ever studied much about it but a bit interested in recently i studied an opposition to the Darwin's theory that our ancestors are supposed to be the mammals living in the water the reason behind this argument is that iif it were apes or monkeys then how could they breed the generation of same kind throughout the world as they could not travel all around in that era instead water organism could travel easily from continent to continent and they only have to change the fins into hands a little more genetic change i m confused i neither satisfied with Darwin nor i pursue such above argument so what could likely be our ancestors according to science? thanx

hello to masterminds waht is a memory resident program in assembly language i want some detail of memory resident program in assembly language also please tell me the sites or links from where i can get elaborate answer to the above question thanx

hey thanks woelen what i predict from your answer is that as the concentration of the reactants continuously decreases the expression comes to be negative also,we introduce negative sign so as to make the expression positive

hello there to all respectable science lovers i would like to ask about the rate of a chemical reaction my question is: why rate expression for the reactants is taken with negative sign? e.g. A+B ----> C+D the rate expression for the reactants is dx/dt=-[A] i need some clarification as i teach chemistry thanks sincerely chemilover
