Matter and Chemical Reactions
The reason we are doing this lab is because we are trying to see what will happen. When you put copper and silver nitrate together. Also after that I will see if any elements reacted and if so which ones and what is the name of the compound they formed.
Hypothesis: If I put the copper into the silver nitrate, then it will make some type of solid.

1.) Read the entire CHEMLAB.
2.)Prepare all written material that you will take into the laboratory. Be sure to include safety precautions, procedure notes, and a data table in which to record you observations.
- Safety Precautions
Always wear safety googles, gloves, and lab apron.
Silver nitrate is toxic and will harm skin and clothing.
Use caution around a flame.
3.) Define the terms physical property and chemical property. Given example of each.
Physical property: is a characteristic that can be observed or measured without changing the sample’s composition. (Ex. Crush, Boil, Freeze, Condense, etc.)
Chemical property: the ability of a substance to combine with or change into one or more other substances. (Ex. Corrode, Ferment, Rust, Burn, etc.)
4.) Form a hypothesis regarding what you might observe if...
a.) A chemical change occurs
- The copper might rust when it when in the solution.
b.) A physical change occurs
The copper might melt when it enters the solution.
5.) Distinguish between a homogeneous mixture and a heterogeneous mixture.
Homogeneous mixture: is one that does not blend smoothly throughout and in which the individual substances remain distinct.
