When a substance has large or strongly-attracted particles, they do not flow freely. For example, water flows very quickly compared to honey. Which property of liquids does this example illustrate?

Viscosity

Explanation:

Viscosity is how thick a liquid is due to internal friction.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
