Determine how many atoms of pure silver will be created when 19.83 x 1023 atoms of copper are used in the following reaction:
cu + 2agno3 -> cu(no3)2 + 2ag
avogadro's number: 6.02 x 1023

Answer : The number of silver atoms produced will be

Explanation : Given,

Number of atoms of copper =

The given balanced chemical reaction,

From the balanced chemical reaction we conclude that,

As, number of copper atoms react to give number of silver atoms.

So, number of copper atoms react to give number of silver atoms.

Therefore, the number of silver atoms produced will be

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
