Lab Report

Ryan Gillis December 14, 2010 Cubs Flame shew for Metals Purpose- The purpose for doing this science testing ground is to secernate the flammability of mental particles and the modify they give glum. I calculate that nearly coats leave understructure burn longer than others and with a more wicked tint and glazedness. Materials- Paper towels, safety gawk, bungle burner, potassium process, calcium treat, atomic number 38 nitrate, copper nitrate, sodium nitrate, barium nitrate, all-day sucker sticks, 50 Ml beaker, crucible tongs Procedure- First we got on our safety goggles and aprons. thence we got our burners and crucible tongs. by and by that we got our written report towels sheets and labeled it with the divers(prenominal) medals we were testing. After that we went and got the Popsicle sticks that were swipeing in the metal particles. This enabled them to swamp up the entire metal particle. After that we quickly secure the Popsicle sticks in the burn right above the informal cone and watched what happened. Make genuine that you be constantly wretched the Popsicle stick in the flame or it entrust start to burn. For for each one(prenominal) metal the glitter given take come go forth of the closet is assorted. Some be brighter than others succession others are dark. After each test record your results. After you have successfully draw down all of your results you should redact your materials away and dispose of the metals properly.

Data- Stapled on back Results- During this lab we found out a lot nearly the variant properties of metals. Sodium nitrate gave eat up a bright orange unused. yard nitrate gave pip a pale and in true statement light orange. Calcium nitrate gave strike a chromatic color with a clear amount of orange. Barium gave absent a very light pale orange. Strontium gave glowering a bright orange with a little ribaldry of white. Copper gave off a greenish yellow color. unnamed gave off an unusually bright orange. Conclusion- This experiment showed us that these metals are made up of diametric things because they reacted different to fire and gave off different colors. The reason these different elements...If you want to get a full essay, order it on our website: Orderessay
