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

Clinical Tip #10 A patient is seated in your dental chair‚ and during the examination prior to choosing a size of sensor; you see a shallow palate‚ and narrow maxilla and mandibular areas. You decide to use a #1 sensor. When taking bitewings with a #1 sensor‚ you cannot get under a deep crown with bitewings. However‚ the patient’s mouth will not accommodate a #2 film. It is best to take an extra periapical film of the tooth with the deep crown‚ so the dentist can give a diagnostic examination

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

Reaction 4- My hypothesis for reaction 4 is that adding hydrochloric acid to solid calcium carbonate produces bubbles maybe. When burning the splint is placed on the test tube‚ the flame is extinguished. Reaction 5- My hypothesis for reaction 5 is that mozzy zinc in the test tube will make smoke come out of
