Question

Few properties are mentioned below. Specify the property as mixture or compounds:

STATEMENT 1: The constituents can be separated easily by physical means.

STATEMENT 2: Has a variable composition.

STATEMENT 3: The composition is always fixed.

STATEMENT 4: Shows entirely different properties from constituent elements.

• A. statement 1 is mixture and rest are compound.
• B. statement 1 and 2 are mixtures and 3 and 4 are compounds.
• C. statement 3 and 4 mixture and rest are compound.
• D. 1 and 3 are compounds are rest are mixture.

Answer 1

The correct option is B

statement 1 and 2 are mixtures and 3 and 4 are compounds.

Elements and compounds mix together in variable ratios to form a mixture of variable composition (it depends on the mixing ratio in which the constituents of the mixture are mixed), whereas elements and compounds combine in fixed ratios to form new compounds with entirely different properties and a fixed composition.
