Question

True or False: Scientists use what they know about the properties of different molecules to separate mixtures. *

Answer 1

True

Step-by-step explanation:

Mixtures are substances with indefinite composition. They consist of two or more elements and or compounds in any proportion by mass.

• Their constituents retain their identities i.e. physical properties are retained.
• Their constituents reacts differently to changed conditions.
• They can easily be separated into constituents by physical methods.

From these properties we can clearly identify that to separate mixtures, we use the differences in the chemical properties of the constituents of the mixtures.
