Higher Education Science 08/04/2015 Julie Day Periodic trends across the period three oxides Objective This experiment is intended to explore the relationship between the physical properties of the oxides of Period 3 elements (sodium to chlorine) and their structures. Argon is obviously omitted because it doesn’t form an oxide. Hypothesis This experiment will be investigating the following properties of the oxides of group three; A) State at room temperature B) Appearance C) Volatility

Swimming Rejuvenating‚ the body mind and spirit…. Fitness development The fitness development of swimming can be classified into1 group and 2 sub-sections: Performing swimming regularly can help one in building cardio which is important for both weight loss and good cardiovascular health. When the workout is increased gradually by swimming strokes in the water‚ the heart rate and muscle activity is improved. This increases blood flow to your muscles‚ which results in more nutrients being delivered

hydrogen peroxide (hair bleaching)‚ oxygen (respiration) Real Life Application of Oxidation: Swimming-pool water treatment Chlorine or chlorine compounds such as Ca(ClO)2 (Calcium Hypochlorite - usually used) and NaClO (Sodium Hypochlorite) are added to water to form HOCl. HOCL is an oxidising agent and it kills microorganisms by oxidising them (by being reduced itself) When chlorine acts as an oxidising agent it is reduced to the chloride (Cl-) ion A reducing agent is a substance that allows reduction

other uncontrollable environmental factors. Introduction An alkyl halide or haloalkane is composed of hydrocarbons with a halogen attached to a sp3-hybridized carbon. It resembles an alkane with a halogen attached to it. Halogens are fluorine‚ chlorine‚ bromine‚ and iodine. Any of these halogens seen to be attached to an alkane‚ could then be identified as alkyl halides. They are generally polar because of the electronegativity difference of carbon (2.5) with the halogen (2.5-4.0). However‚ most
