1.3 g of zinc reacts with excess sulphuric acid. Calculate the volume of hydrogen gas formed at

s. t.p.

[ RAM : Zn=65 ; 1 mole of gas occupies a volume of 22.4 dm3

at s. t.p. ]

A 112 cm3 B 224 cm3

C 336 cm3 D 448 cm3

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

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.
