Balance the following equation by inspection:
cu + hno3 --> cu(no3)2 + h2o +no

3Cu + → 3 +4 + 2NO

Explanation:

Considering the number of each atom in both reactants, it must be equal to the number of each atom in the product. Thus, the number of copper atom, hydrogen atom, nitrogen atom and oxygen atom must be equal on both sides of the equation.

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.
