(H)
Compounds - ANSWERComposed of two or more elements in chemical combination,
meaning they are held together by certain strong electrical forces. They cannot be
separated by filtration or sedimentation.
Formed by combining specific elements in definite proportions such as a ratio of 2:1
Examples: Calcium hypochlorite (Ca(OCl)2), Water (H2O), Carbon dioxide (CO2),
Sodium thiosulfate (Na2S2O3)
Mixtures - ANSWERComposed of two or more elements and/or compounds in physical,
not chemical, combination
They can be separated into their physical components by physical means such as
sedimentation
