* Chemical Reactions Lab
Statement of the Problem:
* We are trying to see if the chemicals are real reactions or not. by testing and balancing them in varies ways to really see if they are true reactions.
* Before this lab we know how to balance equations and we knew the reaction and the all five reaction types and it helped us how to complete this lab.
Hypothesis:
* The possible solutions for each reaction tested is: does it produce a gas, if so what kind, which type of reaction it is, and what the products of the reaction are. We can test most of these with a wood splint that has been burnt slightly.
Materials:
* We first had to get all of are safety gear on like our goggles and are apron and turn on the fume hood because the reactions created many gases and we like to be safe. Also we used, test tubes, test tube racks, CuSO4, Ba(NO3)2, HCl, H2O2, MnO2, C3H8, and a Bunsen burner.
Procedure:
* In this lab we tested many chemical reactions of different solutions mixing.
*First we mixed Zinc with Copper Sulfate, and the copper formed on the zinc in the solution making a single displacement reaction.
*Next we mixed Barium Nitrate and Copper Sulfate, and the reaction was foaming and creation of powder at the bottom of the test tube making it a double displacement reaction.
*After we mixed Magnesium and Hydrogen Chloride the reaction was a single displacement, but the magnesium was being broken down and the solution is very warm in the test tube.
*After the reaction labs we began to test reaction with flame. These tests consisted of H2O2 being heated, C3H8 being heated. Later we mixed Catalyst with the H202 Mixture.
Results (Data):
*In each reaction there was bubbling and changes in each of the mixtures. In the heating reactions they all bubbled at different rates.
Conclusions:
* Each reaction did produce gas and bubbled, we were also able to find out which reaction type each reaction was.
* Our hypothesis was correct because we knew a lot about the lab before we began it.
*I learned in this lab that there are many different reactions in the world of chemicals.
*The only possible errors in the lab would be that we did not use enough of each mixture or that we recorded it wrong.
Bigger font, maybe.
ReplyDeleteAnd more in the procedure.
but after that it will look great(;
just need some pictures of the reactions to spice it up:)
ReplyDeletethe bigger font is nice but you forgot to make the conclusion bigger font
ReplyDeletemissing photos of each reaction, try to create a data table next time.
