Which statement best describes balancing equations and the law of conservation of mass?
A.)There are more atoms in the reactants than in the products, and the total mass is the same in the reactants and in the products.
B.)The number of atoms is the same in the reactants and in the products, and the total mass is the same in the reactants and in the products.
C.)There are fewer atoms in the reactants than in the products, and the total mass is less in the reactants than in the products.
D.)There are more atoms in the reactants than in the products, and the total mass is higher in the reactants than in the products.

The number of atoms is the same in the reactants and in the products, and the total mass is the same in the reactants and in the products.

Explanation:

B.)The number of atoms is the same in the reactants and in the products, and the total mass is the same in the reactants and in the products.

Explanation:

This makes sense because according to the law of conservation of mass, mass can not be created or destroyed. So when balancing equations you are merely transferring mass so it should remain the same from when you start.

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.
