Question

what exactly would you observe and see at the end of the reaction of zinc and lead nitrate? include in formation about colour changes and bubbles.
you can use the following equation to help;
zinc+lead nitrate(arrow) zinc nitrate+lead

Answer 1

What I will write will not be inclusive. You should read about the activity series and note that Zn is above Pb in the series. Any metal HIGHER in the series will displace an ION LOWER in the series. Note that Zn is higher than Pb; therefore, Zn metal will displace Pb ion.
Zn + Pb(NO3)2 ==> Zn(NO3)2 + Pb.

This is a single replacement type reaction. The Pb will plate out on the Zn and eventually form small particles of Pb at the bottom of the beaker/reaction container. This should get you started.
