Question 24 of 50 2 Points

What is occurring during boiling?

A. Solute particles increase in kinetic energy until they knock solvent particles out of the solution and into the air.
B. Vapor pressure is greater than atmospheric pressure and water molecules escape from the solution into the air.
C. Atmospheric pressure is greater than vapor pressure, and water molecules escape from the solution into the air.
D. Solvent particles increase in kinetic energy until they knock solute particles out of the solution and into the air.

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.
