states that in any chemical reaction, the mass of the substances that react equals the mass of the products that are formed.
A) The law of conservation of mass
B) The law of definite proportions
C) The atomic theory of matter
D) The law of conservation of matter
Answer (2)
The question refers to the law of conservation of mass, which states that the mass of reactants equals the mass of products in a chemical reaction. This principle ensures that matter is not created or destroyed during such reactions. Antoine Lavoisier is credited with developing this fundamental concept. ;
The chosen answer is the law of conservation of mass, which states that the mass of reactants equals the mass of products in a chemical reaction. This principle ensures that matter is not created or destroyed during such reactions and was established by Antoine Lavoisier in the 18th century. A classic example is the reaction between hydrogen and oxygen to form water, where the total mass remains constant before and after the reaction.
