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.

64799.4 J

Explanation:

The following data were obtained from the question:

Mass (M) = 1.05 kg = 1.05 x 1000 = 1050g

Specific heat capacity (C) = 0.9211 J/g°C

Initial temperature (T1) = 23°C

Final temperature (T2) = 90°C

Change in temperature (ΔT) = T2 – T1 =

90°C – 23°C = 67°C

Heat required (Q) =?

The heat required to increase the temperature of the kettle can b obtain as follow:

Q = MCΔT

Q = 1050 x 0.9211 x 67

Q = 64799.4 J

Therefore, 64799.4 J of heat is required to increase th temperature of the kettle from 23°C to 90°C.
