Data Table
On the table below, record your observations before and after the interactions and explain how mass was conserved. Describe the changes in properties that prove a chemical reaction occurred. The first row is an example.
Observations Before Interaction
Observations After Interaction
How was mass conserved?
Proof of a Chemical Reaction
Example: Sugar + Heat
The sugar is in tiny white particles in a pile. Heat is not seen but is implied by the heat source. The pile of sugar in the pot has a mass of 100 grams.
There is a solid, light brown mass at the bottom of the pot. It has a mass of 100 grams.
The mass of the sugar is the same in melted form as it is in solid crystal form.
There was not a chemical reaction. Sugar did not change composition. It only melted. Melting point is a physical property, and this is a physical change.
Steel Wool + Oxygen (Fire)
Egg + Heat
Water + Heat
Zinc + Hydrogen Chloride
Sodium Hydroxide + Copper Sulfate
