Chemical Reaction Lab*

Katrina, Nika, and I did all sorts of different labs and found out how they reacted.

We took a piece of copper wire shining it up with emery cloth. Then we lit the Bunsen burner and held the copper over it with tongs. the copper turned black then green .
-Cu+O2 heat CuO
 We put hydrogen peroxide in a test tube. then added manganese dioxide to the test tube. Catching the gasses in a separate test tube we put a burnt splint in the gasses and it made the coals burn hotter.
-H2O2 MnO2 O2+H2O

We had hydrochloric acid and we filled a test tube half full. Then we took a short piece of magnesium metal and placed it in the acid. Catching the gas that was produced by the acid and magnesium in another test tube. Then we lit a match and put it in the gas and the flame made a popping noise.
 -2HCL(ag)+Mg-H2+MgCl2

We placed copper 2 carbonate into a test tube and heated it, then we caught the gasses that were given off. we lit a splint and put it in the gas.
-CuCo3+heat Co2=CuO

 We had to light a Bunsen burner, then we cut a short piece of magnesium and placed it over the burner holding it with tongs. The magnesium got hott enough and lit up and produced a bright white light.
-Mg+O2heatMgO

We filled a test tube with ammonium carbonate. Then we gently heated this substance and we wafted the smell to us. It smelled like Bleach.
-(NH4)2Co3heatNH3+Co2+h2O

we mixed Potasium iodine and lead 2 nitrate. and we produced a yellow color.
- Ki+Pb(No3)2-KnO3+PbI2
