Notes - The earth is many layers on top of each other - Lots of heat and pressure in the center - Electronegativity Guided activity: Earth Science - Making Rocks Silicates: Combination of silicon(s;) and oxygen(o) 95% of earths crust and 97% of the earths mantle is made of silicates. Earth 1.Core: made of iron and nickel 2.Outer Core: Made of liquid iron and nickel. 3.Mantle: Made of molten rocks (silicates) 4.Crust: Outer is solidified mantle Na2 SiO3 : Sodium silicate Calcium Sodium Sodium Calcium Chloride Silicate Chloride Silicate Ca Cl2 + Na2 SiO3 --> 2 NaCl + Ca SiO3 Sodium is further apart than calcium meaning it is more reactive. Will KCl + ZnO React? No. Furthest chemicals have the most reaction and will kick any others out or not react at all. What Happened: After all of our equipment and materials were ready, Andrew mixed in distilled water with a strong chemical that would help a lot with the experiment. We needed distilled water because it contains zero salts. We needed a clean additive, and then our mixture of 1.5/1 was mixed in a beaker and distributed into multiple test tubes. We were then ready to proceed. Details: We first put calcium chloride into a test tube, and the reaction was fairly quick. It immediately started to slowly climb to the top of the test tube. Next was cobalt chloride, and it wasn't long before this one changed into purple and blueish colors. This substance also shot its way to the top of the tube. Finally was copper chloride, and this substance seemed to be lazy. It had very little movements towards the top. It was very slow to react, meaning it was closer than the rest to our clear liquid on the periodic table than the rest. Moving forward: What's next?
I enjoyed this experiment in particular, I think it would be fun to learn about different substances on the periodic table and see which ones are more reactive than the others. There's a whole world of chemistry that we haven't explored yet.
