Decomposition!
The reaction is dehydration.
endothermic reaction
boner
The copper and silver will combust.
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.
The reaction is dehydration.
endothermic reaction
Neutralisation reaction.
it's a physical reaction because you can get it back to copper oxide
I'm not quite sure how to answer this question except to say that this is an exo-thermic reaction. Does that answer it for you?
exothermic
synthesis
When potassium metal and water are mixed, a chemical reaction occurs. This exothermic reaction produces hydrogen gas and potassium hydroxide, which dissolves in the remaining water. This reaction can be vigorous and produce light, heat and sound.
This is an endothermic reaction.
