Saftey Rules
Make sure that you pull your hair back if you have long hair. That you always have your goggles on and your sleeves pulled up if you have long sleeves.
Chemical Reactions
MnO2
This solution is an Hydrogen Poroxide Product.
How to do this
Once you light the candle, burn the wooden splint, tip it upside down, blow it out and place it inside of the test tube.
Chemical Reaction
You do the exact same thing that you did for the previous lab and see the difference between the two chemicals and how they react to fire and wood.
Chemical Reaction Part 2
Once we blew out the lit stick and put it into the tube (Not touching the water) it only got foggy and warm. Which means it had a temperature change and gas being released. This reaction was a Decomposition reaction.
Chemical Reactions are cool!
After we poured NaI into PbNO3 this is what it turned out to be. This Chemical Reaction had color change, temp change, and gas being released.
Chemical Reaction
This reaction is a Double Replacement
Chemical Reaction
This reaction is a Single Replacement
Chemical Reaction
Once we put the zinc in the acid it made it have a color change, gas being released, odor change, temp change, and precipitation.
