Question

Cu+ agno3->cu(no3)2 + ag окислительно восстановительная реакция

Answer 1

Cu + 2AgNO3 = Cu(NO3)2 + 2Ag

$Cu^{0} - 2e = Cu^{+2}$ |1| восстановитель, реакция окисления
$Ag^{+1} + 1e = Ag^{0}$  |2| окислитель, реакция восстановления 

Answer 2

Oxidation-Reduction Reaction: Cu + AgNO3 -> Cu(NO3)2 + Ag

The reaction between copper (Cu) and silver nitrate (AgNO3) results in the formation of copper(II) nitrate (Cu(NO3)2) and silver (Ag). This is an example of an oxidation-reduction reaction, where one substance is oxidized and another is reduced.

Oxidation and Reduction: In this reaction, copper undergoes oxidation, while silver nitrate is reduced. Oxidation involves the loss of electrons, while reduction involves the gain of electrons.

Balanced Chemical Equation: The balanced chemical equation for the reaction is: Cu + 2AgNO3 -> Cu(NO3)2 + 2Ag

This equation shows that one mole of copper reacts with two moles of silver nitrate to produce one mole of copper(II) nitrate and two moles of silver.

Explanation: When copper reacts with silver nitrate, the copper atoms lose electrons to form copper(II) ions, while the silver ions in silver nitrate gain these electrons to form solid silver. This transfer of electrons is what characterizes an oxidation-reduction reaction.
