**Statement A: Atoms can exist independently**
Atoms are the basic building blocks of matter, and they are the smallest unit of an element that retains the properties of that element. Atoms are not typically found in isolation in nature. Instead, they tend to combine with other atoms to form molecules or compounds. So, statement A is false.
**Statement B: The law of constant proportions is applicable only to pure chemical compounds**
The law of constant proportions, also known as the law of definite composition, states that a pure compound always contains the same elements in the same proportion by mass. This means that, regardless of the source or method of preparation, a compound will always have the same ratio of elements.
For example, water (H2O) is always composed of 2 hydrogen atoms for every 1 oxygen atom. This ratio remains constant, regardless of whether the water is sourced from a lake, a river, or a laboratory.
However, the law of constant proportions does not apply to mixtures. In a mixture, different substances are combined physically, but they do not chemically react with each other. Therefore, the proportions of the different components in a mixture can vary.
For instance, a mixture of salt and sand can have varying amounts of each component, depending on how it is prepared. This mixture does not follow the law of constant proportions because the ratio of salt to sand can change.
Based on this explanation, statement B is true. The law of constant proportions only applies to pure chemical compounds, not to mixtures.
