rock because it’s a calcium carbide and was known here in the Philippines as kalburo. When this chemical compound is mixed with water there will be a chemical reaction and it produces acetylene gas. The two anions of carbon‚ the carbide (C4-) and dicarbide (C22-) ions react with water to produce hydrocarbons. The carbide ion gives methane gas‚ and the dicarbide ion gives acetylene gas. This video shows the reaction between calcium carbide and water to produce acetylene and calcium hydroxide. Acetylene

Church & Dwight: Time to Rethink the Portfolio I. INTRODUCTION A. EXECUTIVE SUMMARY 1. Summary statement of the problem: Church & Dwight Co. Inc. is a 160 years old company that has been working to build a market share on a brand name that is rarely associated with its name. In spite of having this status in the eye of consumers its product can still be found among several consumer products in 95% of all U.S. households. Because of its rapid growth brought by its several acquisitions

The effects of parathyroid hormone on serum calcium are mediated by increasing renal tubular resorption of calcium‚ increasing calcium absorption from the

Emission Spectra & Flame Tests Intro The emission spectrum is used in modern chemistry to help further studies of wavelengths and the spectrum. When a metal in a compound reacts in a flame and produces a color‚ it helps to show the strongest color in the emission spectrum. The purpose of performing these operations on the flame was to see how different metals would react. Using a spectroscope‚ it is possible to observe the line emission spectrum produced by sunlight‚ artificial light‚ and

example‚ a mixture of polcaprolactone (PCL) which is biodegradable and acts as a matrix materialis used to manufacture a scaffold for producing a mixture of bone and cartilage and then implanted into a rabbit in one of the studies. Also‚ adding tri-calcium phosphate (TCP) improves the biocompatibility to enhance bone regeneration. But still it is difficult to maintain the integrity of the scaffold for a long time enough to form healthy and strong bone(Gibson‚ Rosen‚ & Stucker‚ 2010‚ p.

Unur Abdul Kader T.A: Katie Experiment 22: Molar Solubility‚ Common-Ion Effect Abstract The purpose of this experiment was to determine the molar solubility‚ the solubility constant‚ and the effect of a common ion on the molar solubility of calcium hydroxide. To accomplish this the experiment was split into two parts; part A and Part B. in Part A of the experiment a standardized 0.05 M solution of HCl was titrated into a 25 mL solution of saturated Ca(OH)2 which contained 2 drops of orange methyl
