The reasons why copper dissolves in AgNO3 solution but remain insoluble in Pb(No3)2 solution.help me.thank you
See the activity series.
A metal will displace any ION BELOW it in the activity series.
Cu is ABOVE Ag but Cu is below Pb.
Cu + 2AgNO3 ==> Cu(NO3)2 + 2Ag
Cu + Pb(NO3)2 ==> No reaction because Cu is BELOW Pb in the series.
Solve simultaneously: 27 raise to power of x-y =9/3 raise to power of x,2 raise to power of x-2y =0.5.THANK YOU.
Your post will get lost here. You should post a new one at the top of the page and use the subject of math.
