Conclusion The purpose of this experiment was to teach whether magnetic cores underwent physical or chemic switchs when added to other chemics. In ein truth action came a reply. Chemicals were pickings charge of the reactants. This lab focus to a greater result on both(prenominal)(prenominal) quantitave and qualitative measurements. The substances we find in this lab were strapper, magnesium, sodium chloride, sugar, yard chlorate, single, and iron. We observed the substances manner before and aft(prenominal) they were composite. We looked for specific indications of chemic changes, color change, formation of a precipitate, and heater. If one or more than of these occurred, a chemical change took place. If none of these occurred, then no reaction occurred. Since no song were calculated in this experiment, precision and accuracy was not a big deal. The first scarcely a(prenominal) substances we experimented with had chemical changes. Which ment that each substance changed from its original property. Copper underwent a reaction to form copper oxide. Sodium chloride before and aft(prenominal) it was obscure was white. The sodium chloride did endure a change because the crystals were atomic after being interracial.

The succeeding(prenominal) substance was potassium chlorate which was mixed and, bubbles formed, the crystals turned to a liquid, smoke was formed, and then went choke to a solid by forming a precipitate. The smoke given off-key and the precipitate that was formed both are evidence of a chemical change. Also it was an display case of exothermic reaction. Iodine is genuinely toxic. Before the iodine was mixed it was low silver, metallic, flake like, solid. The iodine turned to a purpleness vapor immediately. This process of gloaming from solid to gas ground is called sublimation. After the vapor went brook to the solid state, it was still dark silver, metallic, flake like, solid. In every mixture came a reaction that was observed with our own eyes.If you esteem to get a safe essay, order it on our website: Ordercustompaper.com
