The lab was not infallible‚ however‚ as the samples could have been easily contaminated‚ mixed‚ or out of order. Also‚ burning the woods splints caused the flames to appear orange‚ affecting the results in several possible ways. The results seemed similar to each other and many of them seemed to share a slightly orange hue‚ perhaps because the splint was being burned unintentionally at the same time. The first unknown was identified as Calcium due to the similarities in color and the second

Make a few crystal stick to the splint 2.Hold the end of the splint with the crystals in the burner flame and watch the first color you see. When it changes to orange‚ the splint is burning and we don’t care about that color 3. Use your chart from your prelab to estimate the wavelength of the color being produced

affected. Clubfoot is most common in children who suffer from spina bifida who have an L4 or L5 motor level. Many orthopedic surgeons instead of serial casting suggest early taping and gentle manipulation followed by an application of a well-padded splint. The reason for this is because serial casting can cause skin irritations and breakdown. Another technique manipulation and casting is a treatment that begins shortly after birth. It involves slowly stretching out the tightened muscles and holding

Seven wooden splints that were soaked in distilled water were then placed into a 250 ml beaker half-full with deionized water to continue soaking. Six weighing dishes were then labeled “NaCl”‚ “Sr(NO3)2”‚ “CuCl2”‚ “LiCl”‚ ” KCl”‚ and “BaCl2” were obtained. Each contained a scoop full of each metallic solid in the corresponding weighing dish. After this‚ the Bunsen burner was carefully lit. The soaked end of one of the metallic splints was then dipped in one of the metallic

Also that the heated solids caused condensation that put the fire on the splints out. The experiment could have been flawed due to measurements.
