Why is there no reaction between solid silver and copper (II) nitrate

For the reaction to occur, it is necessary that the metal which replaces the metal from the compound LIES above that metal in the ELECTROCHEMICAL SERIES(ECS). The metal in the compound here is Copper (II) nitrate where as the metal trying to displace is silver. Silver lies below the copper in a ECS, that means Copper is more reactive than silver. The reaction is not possible because more reactive metal displaces less reactive metal from its compound, and silver is LESS reactive than copper so it cant displace the copper from copper nitrate.

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
