Purpose- The purpose of this lab was to display to us a variety of different reactions using an eclectic of things in the chemistry lab: including magnesium, methanol, and fire. This was to make what we are doing on paper in class a real life circumstance.
Analysis questions
1) A) Part A 2Mg+O2 à(delta/heat) 2MgO
Part B 2CuCO2 à(delta) 2Cu+CO2+O2
Part C Zn+HCl à H2
Part D CuCl2+2NaOHà 2NaCl+ Cu(OH)2 …show more content…
Part E Zn+CuCl2à Cu+ZnCl2
Part F H2O2à (KI catalyst) H2+O2
Part G CH3OHà CO2+2H2O Part | Qualitative | Quantitative | Part A- | Lit up into a bright like and turned into a turned a rusty glowing color and smoked into a white ash | Magnesium about 3cmCrucible, top & Magnesium – 33.8gAfter- same weight | Part B- | Once the splint was in the stuck into the test tube the fire on the stick went out.
This happened because of the carbon dioxide | Weight before 120.3 g | Part C | Zinc with Hydrochloric acidIt bubbled up like it was boiling and produced hydrogen gas. | Zinc weight- 1.5 | Part D | It took a little while of just clear then turned into a Carolina blue precipitate | | Part E | Zinc turned fire red (The copper was already red)Liquid turned a tar heel blueWarm on the bottom | | Part F | H2O2 Hydrogen proxide KI |

2) 2 H2O2(aq) --> 2 H2O(l) + O2(g)(Cool science)
The elephant toothpaste is a catalyst because of the decomposition of the hydrogen peroxide into water and oxygen is catalyzed by the iodide ion. (cool science)
Conclusion- This lab made our paper work a reality. Getting to see the reactions with all the different chemicals in different forms was very eye opening and fulfilled the stereotypical chemistry I have been looking forward to since the semester began. This lab taught me more than anything to always be cautious of my safety procedures however. Throughout the couple days of lab, I was burned, cut, and busied, by not being cautious. The coolest lab we have done so far.
