Difficulty: EasyDistinction Between Elements, Compounds, and Mixtures

The constituent elements of a chemical compound retain their individual chemical properties and can combine in any variable proportion by mass.

Answer: Answer

Answer

The statement is False. In a chemical compound, constituent elements lose their individual chemical properties and combine in a fixed ratio by mass according to the law of definite proportions.
The statement is false because chemical compounds are pure substances formed when elements combine chemically in definite, fixed mass ratios, creating unique properties different from their constituent elements.

Step-by-Step Solution

1
Analyze the properties of chemical compounds versus physical mixtures.
Compounds undergo chemical bonding, resulting in a new substance with entirely unique properties, whereas mixtures retain individual component properties.
To recall fundamental definitions distinguishing compounds from mixtures.
2
Evaluate the rules of proportion for compounds and mixtures.
Compounds have a strict fixed composition by mass (law of definite proportions), unlike mixtures which possess variable compositions.
To verify whether variable proportions apply to compounds.
