there is no CuNa3 ....
Added:
..... and PbNO3 doesn't exist as well.
If questioneer probably meant Pb(NO3)2 and Cu(NO3)2 then the answer would have been: there is NO REACTION.
When Pb(NO3)2 (lead nitrate) is mixed with KI (potassium iodide), a yellow precipitate of lead iodide (PbI2) is formed. This reaction can be represented by the equation: Pb(NO3)2 + 2KI -> 2KNO3 + PbI2.
It has to be Pb(NO3)2 with NaCl as Pb has a +II oxidation state and NO3 has -I oxidation state. The reaction is the following: Pb(NO3)2 +2NaCl ----> PbCl2 + 2NaNO3
The chemicals which are involved in a reaction are called Reagents or Reactants
Mixture... the cookies and ice cream and mixed together as there was no chemical reaction involved. It is heterogeneous because they are not evenly mixed together.
The Nucleophilic substitution of Halo alkanes
Just because one has mixed chemicals together doesn't mean one will get a chemical reaction. The two chemicals could stay neutral when mixed. So, no just because a chemical is mixed it doesn't have to have a reaction.
There is no Mixed Number as there is no Whole Number involved.
its a chemical reaction
nothing
Any reaction occur in this case.
When copper sulfate and iron are mixed, a redox reaction will occur. The iron will displace the copper in the copper sulfate solution, forming iron sulfate and copper metal. This reaction is a classic example of a displacement reaction.
When acid reacts with base, that is a neutralization reaction.
