g The Law of Conservation of Energy states that no energy can be created or destroyed, only transferred or transformed. An example of the Law in the laboratory is

a polar bond is formed when electrons are shared unevenly between atoms

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m
