What are the basic laws of chemistry?
What are the basic laws of chemistry?
The basic laws of chemistry include the law of conservation of mass, the law of definite proportions, and the law of multiple proportions.
Explain the law of conservation of mass in chemistry.
Explain the law of conservation of mass in chemistry.
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction, but is conserved.
What is the law of definite proportions in chemistry?
What is the law of definite proportions in chemistry?
The law of definite proportions states that a chemical compound always contains the same elements in the same proportion by mass.
Flashcards
Law of Conservation of Mass
Law of Conservation of Mass
Mass is neither created nor destroyed in a chemical reaction.
Law of Definite Proportions
Law of Definite Proportions
A chemical compound always has the same elements in a fixed ratio by mass.
Chemical Reaction
Chemical Reaction
A process where substances rearrange to form new ones.
Study Notes
Basic Laws of Chemistry
- There are two fundamental laws in chemistry: the Law of Conservation of Mass and the Law of Definite Proportions
Law of Conservation of Mass
- States that matter cannot be created or destroyed in a chemical reaction
- Mass of reactants is equal to the mass of products
- Matter can only change form, not quantity
- Applies to all chemical reactions, whether they occur naturally or artificially
Law of Definite Proportions
- States that a chemical compound always contains the same proportion of elements by mass
- Regardless of the source or method of preparation, the ratio of elements in a compound remains constant
- Applies to all samples of a given compound, whether naturally occurring or synthesized in a lab
