Statement A: Atoms can exist independently.
Statement B: The law of constant proportions is applicable only to pure chemical compounds.
Explanation:
Statement A: Atoms can exist independently.
- This statement is not entirely true. While atoms are the basic building blocks of matter, they do not exist independently in nature. Atoms are constantly interacting with other atoms to form molecules or compounds.
- Atoms combine with other atoms through chemical bonds to form stable structures. These structures can be simple, such as diatomic molecules like oxygen (O2) or complex, such as the arrangement of atoms in a crystal lattice.
- However, isolated atoms can exist in certain conditions, such as in a vacuum or in highly controlled laboratory settings. But in general, atoms are more commonly found in compounds or molecules.
Statement B: The law of constant proportions is applicable only to pure chemical compounds.
- This statement is true. The law of constant proportions, also known as the Law of Definite Proportions, states that in a pure chemical compound, the elements are always present in the same proportion by mass.
- This means that regardless of the amount or source of the compound, the ratio of the elements in the compound will always be the same. For example, water (H2O) will always have a ratio of 2 hydrogen atoms to 1 oxygen atom by mass.
- This law does not apply to mixtures, where the components can vary in proportion. In mixtures, the elements or compounds are not chemically combined, and their proportions can be changed without breaking any chemical bonds.
Conclusion:
- Statement A: Atoms can exist independently - False
- Statement B: The law of constant proportions is applicable only to pure chemical compounds - True
Therefore, the correct answer is option 'B' - Statement B.
Statement B: The law of constant proportions is applicable only to pure chemical compounds.
