How does changing the amount of one substance affect a mixtures identity and a compounds identity iscience?
pychu [463]

Explanation:

A compound is defined as follows.

  • Compounds are pure substance.
  • The atoms bonded in a compound are in specific proportion.
  • A compound is formed by chemical combination.
  • For a compound, melting point and boiling point is defined.

A mixture is defined as follows.

  • Mixtures are impure substance.
  • The bonded atoms in a mixture are in any proportion.
  • A mixture is formed by physical combination.
  • For a mixture, melting point and boiling point is not defined.

On changing the amount of one substance will affect the formation of compound as a compound requires atoms to be bonded in a specific proportion. Whereas changing the amount of one substance will not affect the formation of mixtures  as atoms can be bonded in any proportion in a mixture.
