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.

What the spectator ions in silver sulfate plus Barium nitrate reaction?
The spectator ions are Ag+ and (NO3)-.
What happens when silver nitrate solution is stored in zinc vessel?
Some of the silver ions from the silver nitrate solution are deposited as metallic silver on the contacted parts of the zinc vessel and are replaced by half as many zinc ions in the solution.
What reactions extract the copper metal from the ore?
There are two main types of reactions used for extracting copper form its ore. In one reaction, copper oxides reduced by carbon to produce carbon dioxide and pure copper. In the second reaction, Copper ore is dissolved, then reduced by iron ions to form Cu+ which forces the copper to let go of its impurities and these copper ions are then fully reduced by a chemical reaction to form Copper metal. See related links for more information about the second reaction.
Potassium chloride and silver acetate react to produce silver chloride and potassium acetate. Which reaction has occurred?
The reaction you describe in words is: KCl + AgCH3CO2 → AgCl + KCH3CO2 This type of reaction is known as a "double replacement reaction" aka "double displacement reaction" aka "metathesis reaction." A double replacement reaction is a chemical reaction where two reactant ionic compounds exchange ions to form two new products compounds with the same ions. In this case the ions are K+ , Cl-, Ag+ and C2H3O2−. Note that potassium chloride (KCl), silver acetate (AgCH3CO2) and potassium acetate (KCH3CO2) are all quite soluble in water. Silver chloride (AgCl) is not particularly soluble in water (520 μg/100 g at 50 °C) and will precipitate out as the reaction occurs.
What is the reaction product of Fentons reagent with silver?
The reaction product of Fenton's reagent (a solution of hydrogen peroxide and ferrous iron) with silver is typically silver oxide (AgO) or silver hydroxide (AgOH) depending on the conditions of the reaction. These products are formed when the silver ions present in the solution react with the hydroxyl radicals generated by Fenton's reagent.
Can silver nitrate be in a redox reaction?
With what? Not enough detail, but silver is not very electropositive. Pretty much any compound or chemical entity can be involved in a redox reaction of some kind. The obvious redox reaction involving silver nitrate would involve silver ions being reduced to silver metal, plus some corresponding oxidation reaction.
What happen in the reaction between chlorine and iodine ions?
The chlorine is reduced to chloride ions and the iodide {note correct spelling} are reduced to elemental iodine.
What kind of reaction takes place when a copper wire is added is to a beaker of silver nitrate?
A displacement reaction, in which the copper dissolves to form copper nitrate and replaces silver ions in the original silver nitrate, reducing the silver ions to metallic silver.
Are silver ions examples of ionic bonds?
Silver ions are only one half of a ionic bond. Take a simple ionic compound, one half of which is silver, for example silver bromide. This contains both Ag2+ (silver) and Br-(Bromine) ions. The bonds between these two different ions are ionic bonds
What is the Function of cupric sulfate in benedict's solution?
These Copper(II) ions are reduced to insoluble Copper(I) ions, while the reaction.
What type of the reaction is cl2 2kbr2kcl br2?
The reaction of chlorine with potassium bromide is a reduction-oxidation reaction. The chloride oxidizes bromide ions to molecular bromine, and itself is reduced to chloride ions.
What the spectator ions in silver sulfate plus Barium nitrate reaction?
The spectator ions are Ag+ and (NO3)-.
What will happen if the silver bromide is kept for some time in sunlight?
The silver ions in the exposed area will be reduced to black metallic silver in a matter of minutes.
What are the spectator ions in silver sulfate plus barium nitrate reaction?
The spectator ions are Ag+ and (NO3)-.
What is the oxidation half-reaction for Fe 2hcl FeCl2 H2?
Oxidant half reaction: 2H+ + 2e- --> H2 Reductant half reaction: Fe --> Fe2+ + 2e- Tribune ions: 2Cl- --> 2Cl-
What species is reduced in the reaction Fe plus AgNO3 Fe(NO3)3 plus Ag?
Fe + 3AgNO3 ==> Fe(NO3)3 plus 3Ag The oxidation number of Ag in AgNO3 (on the left side) is 1+ and in Ag (on the right side), it is zero. Thus, in this reaction, silver (Ag) has been reduced.
How many electrons are gained in the half reaction?
In the half reaction where an oxygen molecule becomes into two oxide ions, it obtains 4 electrons from the oxidising substance.
