Which of the following may be an correct statement?
Law of Definite Composition is also known as Law of Multiple proportion.
Mass can neither be created nor destroyed is Law of Conservation of mass
Antoine Lavoisier conducted many experiments regarding volume.
Six basic laws are required to govern the combination of elements to form compounds
Answers (1)
The correct statement is mass can neither be created nor destroyed is the Law of Conservation of Mass. On conducting many experiments regarding combustion and noticing various physical and chemical changes, there is no change in overall mass hence conservation of mass.
The law of constant proportions, also known as Proust's law or the law of definite proportions, states that the elements present in a chemical compound are always in a fixed ratio by mass. This means that regardless of where a pure sample of the compound comes from, it will always contain the same elements in the same mass ratio. For example, pure water will always have hydrogen and oxygen in a fixed mass ratio of approximately 1:8.
Antoine Lavoisier conducted many experiments regarding combustion
Antoine Lavoisier reported the results of his first experiments on combustion in which he reported that when phosphorus burned, it combined with a large quantity of air to produce acid spirit of phosphorus, and that the phosphorus increased in weight on burning.
Five basic laws are required to rule the combination of elements to form compounds. They are Law of Conservation of Mass, Law of Definite Proportions, Law of Multiple Proportions, Gay Lussac’s Law of Gaseous Volumes, and Avogadro’s number.
