Hi Katy,
In the problem of amalgam fillings, Saliva is working as the conducting medium, so it's equivalent to the solutions and salt bridge in a galvanic cell
As for the question about the galvanic cell, this is true. The galvanic cell stops when the anode strip depletes or when ions of the cathode deplete.

miss aya how do we balance these eqz?and prve redox??
ReplyDeleteh20--->h2.o2
and wat does migration of ions mean???
thxxxxxxxxxxxxxxxxxxxxxx miss yaa really
ReplyDeletemissssssssssssssssss aya yalla balance it plzzzzzzzzzzz i need it
ReplyDeletehey miss aya ... how are you? i miss u !
ReplyDeletemiss i wanna ask you...in the problems of cracking and when we are asked to find the number of carbons and hydrogens in them (for ex: CxHy -> C6H14 + C3Hy ...how can we find this ? given that CxHy is an alkane and C3Hy is an alkene ) after all..i know how to find X & Y but i want the right method to write the answer .can u give it to me plz ...mwa i love u :)
y is the same number...If C3Hy is an alkene, this means it follows the formula CnH2n, then it has 6 hydrogens, then y=6
ReplyDeletenow,if CxHy is an alkane and it has 6 hydrogens (since y=6), then it must obey the general formula CnH2n+2, since 2n+2=6 it means that n=2
so x=n=2
so the alkane is C2H6 and the alkene is C3H6
