spectator ions in a double replacement reaction
Partners are exchanged in a double replacement reaction.
For a double replacement reaction to take place, one of following must occur:One product is only slightly soluble and precipitates from solutionOne product is a gas that bubbles out of the mixtureOne product is a molecular compound
The change in color indicates that a chemical reaction has taken place.
Evidence of a double displacement reaction includes the formation of a precipitate (solid) when two solutions are mixed, a color change, or the formation of a gas or a distinct odor. Observing any of these changes typically indicates that a chemical reaction has taken place.

A double replacement takes place. And a precipitate is formed called AgCl. It is solution on CuNO3.
1) Formation of a precipitate 2) Usually there is a colour change. 3)Neutralization reactions (also a double displ. reaction) involving an acid and a base form water which is a clue.
A double replacement reaction involves the exchange of ions between two compounds. The general equation for a double replacement reaction is AB + CD -> AD + CB, where A and C are cations and B and D are anions. The products formed are two new compounds.
The change in color indicates that a chemical reaction has taken place.
Condensation Reaction.
Evidence of a double displacement reaction includes the formation of a precipitate (solid) when two solutions are mixed, a color change, or the formation of a gas or a distinct odor. Observing any of these changes typically indicates that a chemical reaction has taken place.
A single-replacement reaction
single-replacement reactions and a double-replacement reactions differ in the fact that in a single-replacement reaction only one element that has a positive charge is oxidized or looses electrons. In double-replacement reactions two elements in a compound that contain a positive charge are oxidized.
it's single-replacement. I took a test with a question like that and got 100%
