    A lack of dissolved oxygen in the river would result in scores of fish‚ plants and other life forms to perish. An increase in dissolved oxygen downstream is surprising as downstream of the treatment plant‚ temperatures are much hotter‚ an averaged increase of about 10 degrees. Although‚ this could be due to the tests at the second site being conducted later in the day whereas the tests at test site 1 were done before midday. The increase in the levels of dissolved oxygen are due to a process called

    natural gases‚ gunpowder and trinitrotoluene (TNT). Although for the combustion reaction to take place there has to be an oxidiser‚ this usually is Oxygen (O2). An oxidiser is a chemical substance that adds Oxygen to complete a reaction (Daily‚ 2015). The oxidiser is usually found in the surrounding air‚ this also concludes to the fact that if you add Oxygen by fanning a flame it will become brighter. Overall meaning that since both explosions and coloured flames undergo a combustion reaction both must

    water becomes oxygen depleted. There are natural cycles of eutrophication in the spring and fall‚ but the body of water can deal with those amounts. When excess waste is added to the water the body of water can no longer control the growth of the algae and the water soon becomes algae ridden and oxygen depleted. The water becomes oxygen depleted because the dead algae goes to the bottom and uses the oxygen in the deeper water to decompose‚ but if there is too much dead algae all the oxygen is depleted

    there is no need for an Argon atom to combine chemically with any other atom to form any bond. Argon’s history begins in 1785 when Cavendish mixed air with oxygen and performed several electrical discharges over a mixture of potassium hydroxide. By this process‚ he converted nitrogen of the air into potassium nitrate. Then‚ he removed the oxygen excess‚ but there still remained a small amount of gas‚ no larger than 1/120 of the original volume of air. He considered that this difference had been caused

    INTRODUCTION: The research topic is based upon the impact of the abiotic factors on community properties in the aquatic ecosystems of bith La Vega and Caroni Swamp. The abiotic factors to be included ate salinity‚ turbidity‚ dissolved oxygen‚ phosphates‚ nitrates‚ pH‚ and temperature. Aqautic abiotic factors have become a prudent issue in these ecosystems affecting the abundance and distribution of species as well as feeding relationships as seen in food webs and food chains. In order to try to solve

    amount is oxygen‚ that’s where VO2max comes into play. VO2max is “the volume of oxygen a person can consume in one minute as he or she exercises at maximum exertion” (paragraph 4). With Team NOVA‚ their VO2max levels were measured before and after their nine months of training; and they were dramatically better after. It’s not the VO2max levels that help with receiving enough oxygen when running‚ it is merely an indicator. The amount of red blood cells present in your body help with your oxygen intake

    Ozone As A Disinfectant Joey Finnegan Section 01 October 3‚ 2010 Ozone is a highly reactive gas composed of three oxygen atoms. Ozone is an unstable gas that can destroy bacteria and viruses. Ozone can have many different effects on humans depending on where it is in the atmosphere‚. Some of these effects can be harmful although some can be good. An excess‚ or high concentration of ozone in an inclosed area can be quite harmful to humans although in moderation and if used properly ozone

    conversion of light energy to chemical energy took place in the chloroplast. In 1881‚ he observed the movement of bacteria towards the chloroplasts in a strand of “Spirogyra” algae. Engelmann hypothesized that the bacteria were moving in response to oxygen generated by the photo synthetically active chloroplasts in the algae. This was one of the first documented observations of positive aero taxis in bacteria. In 1882‚ he performed his famous action spectrum experiment using a device designed and built
