Question

in the laboratory, giselle has a mixture of water and rubbing alcohol. giselle separates the water and alcohol by heating the mixture until the alcohol boils away. what happens as giselle separates the mixture? c. chemical changes b. physical change a. displacement d. increased mas

Explanation:

When separating water - rubbing alcohol mixture by heating until alcohol boils away, no new substances are formed. It is just a change in the state (from liquid to gas for alcohol) due to a change in temperature. This is a physical change. Chemical changes involve the formation of new substances through chemical reactions. Displacement is a type of chemical reaction and there is no change in mass according to the law of conservation of mass in a closed system during this separation process.

Answer:

B. physical change
