Few properties are mentioned below. Specify whether these properties belong to mixtures 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.
statement 1 and 2 are mixtures and 3 and 4 are compounds.
Elements and compounds mix together in variable ratios to form a mixture, whereas elements and compounds combine in fixed ratios to form new compounds with entirely different properties.
