What happens when mix the following metals and solution, 1) copper and tin acetate solution.                        2)copper and silver nitrate.                                                3) lead and copper sulphate. 4) lead and silver nitrate.   I know when you react copper and silver nitrate solution, it produces silver and a blue solid called copper nitrate(Cu(NO3)2). It is caused by replacemenr reaction where copper replaced silver in copper nitrate PLZ HELP WTH THE OTHER 4

Welcome, sakuraraine: to the Chemical Forums.  According to the Forum Rules{click}, we want to see your attempt.

You've done one of the four, and defined it in words.  Can you write it out in chemical nomenclature?  Can you write out the others the same way, and begin to learn what happens in each case?  Can you determine what reactions will go, and what reactions won't.  Its going to get very tedious rapidly, if you're going to list every metal on the periodic table, and every compound, and ask "and this one ... and this one ... and this one ..."

Yes, copper=Cu and silver nitrate=Ag(NO3)2 and when they react: Cu(s) + Ag(NO3)2(aq)>>Ag(s) + Cu(NO3)2(aq).

Good.  Now, lead and copper sulfate, and then lead and silver nitrate, they both contain free elemental lead, how are those two reactions different from each other?  And not just the names of the other reactant, there is a fundamental difference in this case.  Can you apply that concept?
