Write a balanced equation for copper metal and aqueous sulfuric acid react to form a solid copper (II) sulfate, liquid water, and sulfur dioxide solid.

Cu (s) + 2H₂SO₄(aq) —> CuSO₄(s) + 2H₂O (l) + SO₂(s)

Explanation:

Copper metal => Cu

Sulphuric acid => H₂SO₄

copper (II) sulfate => CuSO₄

Water => H₂O

sulfur dioxide => SO₂

The equation for the reaction between copper metal and aqueous sulfuric acid can be written as follow:

Cu + H₂SO₄ —> CuSO₄ + H₂O + SO₂

The above equation can be balance as follow:

Cu + H₂SO₄ —> CuSO₄ + H₂O + SO₂

There are 2 atoms of S on the right side and 1 atom on the left side. It can be balance by writing 2 before H₂SO₄ as shown below:

Cu + 2H₂SO₄ —> CuSO₄ + H₂O + SO₂

There are 4 atoms of H on the left side and 2 atoms on the right side. It can be balance by writing 2 before H₂O as shown below:

Cu + 2H₂SO₄ —> CuSO₄ + 2H₂O + SO₂

Thus, the equation is balanced.

Include the phase of each reactant and product, we have:

Cu (s) + 2H₂SO₄(aq) —> CuSO₄(s) + 2H₂O (l) + SO₂(s)

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.
