12 Questions
The laws of chemical combination summarize the basic principles followed in the interaction of atoms and molecules.
True
The transformation of matter from one form to another is not a focal point of chemistry.
False
When two different types of matter combine, it results in the formation of a compound.
True
The laws of chemical combination are not referred to as the laws of chemical combination.
False
The 18th century studies on heat and combustion were unrelated to the development of the laws of chemical combination.
False
The formation of oxide was not observed when metal was heated in air during ancient experiments.
False
Antoine Lavoisier was the first to establish the principle of conservation of mass during a chemical reaction.
True
During Lavoisier's time, the analytical balance was accurate to perhaps 1 part in 1,000.
False
Antoine Lavoisier heated mercury in a sealed flask with water to observe the formation of a red substance.
False
Joseph Proust disagreed with Claude Berthollet's belief that there are no fixed proportions of elements in a compound.
True
The law of definite proportions states that there are no fixed proportions (by mass) of elements in a compound.
False
The law of conservation of mass was established after Joseph Proust's publication of the fundamental law of definite proportions.
False
Learn about the laws of chemical combination and the atomic theory, including the method for counting atoms in reactions and definite mass ratios. Explore how atoms and molecules interact in chemistry and the transformation of matter.
