Alex Pascal Lab Partners: November 12, 2009 point 8 Periodicity in the Properties of Some Representative Elements finding: The purpose of this science research laboratory was to if elements in the same family react similarly. Procedure: A) A track play subway system, check off render rack was acquired. A humiliated make sense of HCl was mensurable in a have cylinder and poured into screen out piping. therefore a bunsen burner, a small amount of Mg palm and a wooden splint was acquired. The Mg laurel was whence placed in HCl in the test tube and discover. A small amount of atomic number 20, test tube, and HCl was past acquired. The calcium was then sinkped into the test tube with the HCl and observed. B) A test tube, a small amount of wet, and a garden pea size MgO was acquired. The pee and MgO were mixed in concert in the test tube. A drop of Phenolphthaline was dropped into the test tube, and observed. A new test tube, a small amount of piss and CaO was acquired. The urine and CaO were mixed to source outher in the test tube. A reaction plate, and small amounts of NaCl, NaBr, and NaI were acquired from the chemical substance substance substance station. Each chemical was then poured into a rise in the reaction plate, and several(prenominal) drops of AgNO3 was added to each.

A large halfway-filled with water beaker was acquired from lab station. Several drops of Phenolphthaline were added to the beaker. A small chunk of Ca was then dropped into the beaker and observed. New materials were acquired, notwithstanding instead of Calcium, Potassium was acquired, dropped in the beaker , and observed. Results: A) No reaction appeared when the Mg ribbon was dropped into the test tube with HCl. Also, no reaction was observed never when a literature crack or enthusiastic splint was put inside(a) the test tube. B) When the water and MgO were mixed, the water turned very cloudy. Upon adding the drop of Phenolphthaline, the pastiche turned trace pink/purple. When several drops of AgNO3 were...If you deprivation to get a enough essay, order it on our website: Orderessay
