Question

The e c:o mass ratio of a particular compound is the same, regardless of the size or source of the sample."

Options:
a) True
b) False

Answer 1

The e c:o mass ratio of a particular compound is the same, regardless of the size or source of the sample. This is known as the Law of Constant Composition.

Step-by-step explanation:

The statement that the e c:o mass ratio of a particular compound is the same, regardless of the size or source of the sample is True. This statement is based on the Law of Constant Composition or the Law of Definite Proportions. According to this law, all samples of a pure compound contain the same elements in the same proportion by mass.

For example, consider water (H2O) which is a compound made up of hydrogen and oxygen. In any sample of water, regardless of its size or its source, the ratio of hydrogen to oxygen by mass is always 2:16 or simplified to 1:8.

However, it is important to note that while the mass ratio of a compound is constant, different compounds may have the same mass ratio. Therefore, having the same mass ratio does not necessarily mean that samples are the same substance.

Answer 2

The e c:o mass ratio of a particular compound is consistently the same according to the law of definite proportions, making the statement True. This law ensures that all samples of a compound have the same elements in the same mass ratio, and is fundamental to the study of chemical reactions and compounds.

This correct answer is a)

Step-by-step explanation:

The statement 'The e c:o mass ratio of a particular compound is the same, regardless of the size or source of the sample' refers to the law of definite proportions or the law of constant composition.

This law states that a chemical compound will always contain its component elements in a fixed ratio by mass, and this ratio is consistent for any sample of that compound, whether large or small, or obtained from different sources. Thus, the correct answer to the question is True.

The law of definite proportions is one of the foundational principles of chemistry and plays a crucial role in the study of chemical compounds and reactions.

It ensures that the same compound will always have the same chemical characteristics because its composition is consistent. The law is closely related to the law of conservation of mass, which states that mass is conserved in any chemical reaction, meaning that the mass of the reactants equals the mass of the products.
