its to compare the properties of two substances. In doing it, he prepare two flasks containing the substances and labeled them Liquid A and Liquid B. He monitor the boiling points of the liquids and found that the boiling points were 100°C for substand A and 110 C - 112 C for liquid B. How would you classify the two liquids? A. Liquid A is pure substance while Liquid B is a mixture. B. Liquids A and B contain two or more atoms that are chemically bonded. C. Liquid A has varying boiling points while liquid B has a fix boiling point. D. Liquid A maybe homogenous or heterogeneous but substance B is not. For item number 8, two liquids were observed and heated. The data gathered is shown in th table below.

7. Ryan wants to compare the chemical properties of two substances. In doing it, he prepared
two flasks containing the substances and labeled them Liquid A and Liquid B. He monitore
the boiling points of the liquids and found that the boiling points were 100°C for substance
A and 110 C - 112°C for liquid B. How would you classify the two liquids?
A. Liquid A is pure substance while Liquid B is a mixture.
B. Liquids A and B contain two or more atoms that are chemically bonded.
C. Liquid A has varying boiling points while liquid B has a fix boiling point.
D. Liquid A maybe homogenous or heterogeneous but substance B is not.
For item number 8, two liquids were observed and heated. The data gathered is shown in the
