Conservation of Mass Activity Worksheet
Instructions: Observe and analyze the interactions between the substances pictured in the slide show. Compare the properties of substances before and after each interaction. You will submit your completed worksheet for grading.
Data Table
On the table below, record your observations before and after the interactions and note if 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
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 weighs 100 grams.
There is a solid, light brown mass at the bottom of the pot. It weighs 100 grams.
Yes, both the reactants and the products weigh the same.
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
