Chemical Reactions Homework: Copper & Silver Nitrate Reaction

[ride4life]

Homework Statement

When copper metal is placed in a beaker containing a solution of silver nitrate, a reaction occurs which can be represented by the following equation:

2AgNO3(aq) + Cu(s) -----> Cu(NO3)2(aq) + 2Ag(s)

a) Give the net ionic equation to represent this reaction occurring
b) Give one piece of evidence which would indicate that a chemical reaction has occurred.


2. The attempt at a solution
a) i have no idea how to write the ionic equation for this
b) is it that a displacement has happened?

 

[Borek]

Write ionic form first.

What is copper color? What is silver color?

 

[Blueshift5]

it is important to understand and accurately represent chemical reactions. The net ionic equation for this reaction would be:

2Ag+(aq) + Cu(s) -----> Cu2+(aq) + 2Ag(s)

This represents the actual species involved in the reaction and shows the transfer of electrons between them.

One piece of evidence that a chemical reaction has occurred is the formation of a solid (silver) from a solution. This indicates a change in the chemical properties and composition of the substances involved, which is a key characteristic of a chemical reaction. Other evidence could include a change in color, temperature, or the release of gas.
