This is a 'Sngle Displacement' reaction ( A + BC --> AC + B
Zn(NO3)2 + 2Ag ---> Zn + 2AgNO3
Zn(s) + 2AgNO3(aq) --> Zn(NO3)2(aq) + 2Ag(s) is a single displacement reaction. It is also called a single replacement reaction. As you can see, the zinc displaced, or replaced, the silver in the silver nitrate solution.
It's been a long while since chem, but perhaps this will put you on the path. When they're talking about "half reaction" I believe they're referring to one side or the other, of the balanced equation -- what forms from what. In the case of solid copper and silver nitrate, the copper "takes" the NO3 and leaves the silver, previously in solution, to remain as a solid. Cu + 2AgNO3 ---> Cu(NO3)2 + 2Ag
Cu(s) + 2AgNO3(aq) --> 2Ag(s) + Cu(NO3)2(aq)According to the metal activity series, copper is more reactive than silver, so the copper will replace the silver in the silver nitrate compound.https://en.wikipedia.org/wiki/Reactivity_seriesThe silver metal will precipitate out of solution, forming along the piece of copper, which goes into solution, combining with the aqueous nitrate ion. If this reaction goes to completion, all of the copper will go into solution as copper(II) nitrate, and all of the silver metal will precipitate out of solution.
The balanced chemical reaction is: Mg(s) + 2AgNO3(aq) → Mg(NO3)2(aq) + 2Ag(s) This reaction produces silver metal precipitate and magnesium nitrate in solution.
There shall be none as both compounds have same anions (Nitrates)
The chemical reaction between silver nitrate and bromine results in the formation of silver bromide and nitric acid. The balanced chemical equation for this reaction is 2AgNO3 + Br2 -> 2AgBr + 2 HNO3. Silver bromide is a yellowish solid precipitate, and nitric acid is a byproduct of the reaction.
When iodide is mixed with silver nitrate, a yellow precipitate of silver iodide is formed due to a double displacement reaction. This reaction can be represented by the chemical equation: 2AgNO3 + 2KI → 2AgI + 2KNO3.
Equation:Cu + 2 AgNO3 ----> Cu(NO3)2 + 2 Ag
The chemical equation representing the reaction between silver nitrate and calcium chloride is AgNO3 + CaCl2 -> AgCl + Ca(NO3)2. In this reaction, silver chloride and calcium nitrate are formed as products.
The balanced chemical equation for the reaction of lead foil with silver nitrate solution is: 2AgNO3 + Pb --> Pb(NO3)2 + 2Ag This reaction forms lead(II) nitrate and silver.
In the electrochemical series of reactivity of metals, you will find that copper(Cu) is more reactive than silver(Ag). Hence copper will displace silver from silver nitrate, to form elemental silver. Cu + AgNO3 = CuNO3 + Ag
No Reaction
This is a 'Sngle Displacement' reaction ( A + BC --> AC + B
When silver nitrate and sodium chlorate react, they form silver chlorate and sodium nitrate. The balanced chemical equation for this reaction is: 2AgNO3 (aq) + 2NaClO3 (aq) -> 2AgClO3 (s) + 2NaNO3 (aq)
The balanced chemical equation for silver nitrate (AgNO3) plus calcium iodide (CaI2) is: 2AgNO3 + CaI2 -> 2AgI + Ca(NO3)2
