Which of the following chemical equations proves that the law of conservation of mass is in effect? Question 2 options:

Mg2 + LiBr ---> LiMg + Br

2KCl + F2 ---> 2KF + Cl2

Na +O2 ---> Na2O

H20 ---> H2 + O2

it would be a gas formation

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.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
