Sulphuric acid is a typical strong acid. (a) Change the equations given into a different format.

(i) Mg + H2SO4 MgSO4 + H2

Change into a word equation.

(ii) lithium oxide + sulphuric acid lithium sulphate + water

Change into a symbol equation.

(iii) CuO + 2H+ Cu2+ + H2O

Change the ionic equation into a symbol equation.

(iv) Na2CO3 + H2SO4 Na2SO4 + CO2 + H2O

Change into a word equation.

(b) When sulphuric acid dissolves in water, the following reaction occurs.

H2SO4 + H2O HSO4 + H3O+

Explain why water is behaving as a base in this reaction.

(c) Sulphuric acid is a strong acid, ethanoic acid is a weak acid.

Explain the difference between a strong acid and a weak acid​

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.
