What is incorrect about the Law of conservation of mass?a)A given compound always conatains exactly the same proportion of elements by weightb)Mass of reactants is equal to the mass of productsc)Matter can neither be created nor destroyedd)It was given by Antoine LavoiserCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

option A is saying about law of constant proportion...but remaining 3 options r describing about law of conversation of mass

Answer

Law of conservation of mass is given by lavoiser . it states that mass is neither created nor destroyed but it converts one form into another.so A is correct

Answer

according to law of conservation of mass~ mass can neither be created nor be destroyed but option A) is shows law of definite proportion

Answer

The Law of Conservation of Mass is a fundamental principle in chemistry that states that in a chemical reaction, matter can neither be created nor destroyed. This means that the total mass of the reactants before a chemical reaction must be equal to the total mass of the products after the reaction.

However, option A is incorrect because it states that a given compound always contains exactly the same proportion of elements by weight. This statement is not true because the Law of Definite Proportions, not the Law of Conservation of Mass, describes the fixed proportions of elements in a compound.

Here is a detailed explanation of the incorrect option:

Explanation:
The Law of Conservation of Mass, also known as the Law of Mass Conservation, was formulated by Antoine Lavoisier in the late 18th century. Lavoisier is considered the father of modern chemistry and his work on the Law of Conservation of Mass was a significant contribution to the field.

The Law of Conservation of Mass states that matter can neither be created nor destroyed in a chemical reaction. This means that the total mass of the reactants before a chemical reaction must be equal to the total mass of the products after the reaction. In other words, the mass of the substances involved in a chemical reaction remains constant.

However, option A incorrectly states that a given compound always contains exactly the same proportion of elements by weight. This statement is not related to the Law of Conservation of Mass. Instead, it refers to the Law of Definite Proportions, also known as the Law of Constant Composition.

The Law of Definite Proportions states that a compound always contains the same elements in the same proportion by mass. This means that regardless of the amount or source of a compound, the ratio of the masses of its constituent elements is fixed. For example, water (H2O) always consists of two hydrogen atoms and one oxygen atom, and the ratio of the masses of hydrogen to oxygen is always 1:8.

In conclusion, option A is incorrect because it refers to the Law of Definite Proportions, not the Law of Conservation of Mass. The Law of Conservation of Mass states that matter is conserved in a chemical reaction, while the Law of Definite Proportions describes the fixed proportions of elements in a compound.
