i am asked to find the concentration as i have stated in the beginning of my post
my question is , is it possible to deduce the concentration from the volume of the solution that was consumed ? the volume of the solution did decrease * due to the reaction with CaCO3 * , i don't think this...
dont just turn off your mind , nobody is trying to knock you off your choice , people here are trying to help you realize what your choice really is , in the end you are the one who's going to live it , the difficulty is not in studying , if you love physics you will love studying , its in the...
thats what i am supposed to find
i will post the exact numbers in the problem
the volume of the solution is 50 mL , the solution reacted with 0.0101 moles of CaCO3 , * so 0.0202 moles of HCl reacted with the carbonate * , the remaining solution needs 24.6 mL of a specific NaOH solution
25 mL...

basically the forum is advising you to take the reality pill , physics might be what you love , it might be your passion , your love , but marriage is very different from dating
you will have responsibilities , lots of responsibilities * which you seem ready to take * ,you will...
there must be somekind of a misunderstanding , first of all it doesn't matter if the HCl was liquid or gas , its dissolved in a solution , the way i was given the second volume was not direct , anyway let's not speak about moles for a while , the volume of the solution at first was 3 litres ...
basically the question is
i have a solution** of HCl * say 3 litres * it reacted with 1 mole of calcium carbonate * so 2 moles of HCl reacted with CaCO3 * , some of the HCl remained , the volume of the solution after the reaction with CaCO3 is 1 Litre , measure the concentration of HCl .
so...
my apologies , i meant liquid HCl , and by radioactive H2O i meant H2O with radioactive Oxygen isotope , anyway this is not the problem .
my question is
if i have a solution of HCl , for the sake of simplicity let's say it is dissolved in some other solvent , anything other than water , and...
suppose you have 2 litres of pure hcl in a solution of 4 litres of radioactive h2o , so the concentration of HCl is 1/3 of the whole solution , now suppose you neutralized that solution with Sodium hydroxide , what happens to the radioactive solvent ? is it involved in the reaction ? does its...
nevermind , i for somereason thought that electrons come one at a time out of a conductor , i thought of the wire as a two dimensional object , but my logic has been corrected by some comment above . also i know that the movement of charges creates a current , i am just talking about electrons...
you sir deserve a nobel prize just for that comment , that is absolutely correct
it is really harder for me * or anyone who is interested in the subject* to learn things that are not physically correct than to learn complicated real physical things
that is due to the fact that physically...
does this imply that any of what was said above is incorrect ?
i know its a classical description of a quantum mechanical phenomena , but until i learn the real quantum mechanical description , this is pretty sufficient only if it's correct
just to make sure i understand it
if the inductor is alone in the circuit with no other resistors , and even the resistance of the inductor = 0 , the voltage across the conductor must always = to 12 voltage correct ? no matter how the flux changes through time
oh , so the inductor voltage just acts as a voltage drop , i never knew that a voltage drop was opposing the current :D thanks a lot , made lots of things clear
the law of the transformer states that
in primary coil , the EMF = -n multiplied by the rate of change of flux with respect to time
but that law applies to induced EMFs , and since the voltage in the primary coil is not actually induced but rather produced by an external source of A.C , then...
aha \
just a couple of questions
shouldn't Vi = Vemf - IR2 ? since these potential differences are opposite * like two opposing batteries *
now the important one , how much of the original V does the induced Emf reach ? when does V = Vemf ?
