Oxygen Atom And Its Effects On The World

Introduction Water is a precious natural chemical compound that is essential for many organisms in the world. It consists of two hydrogen atoms and one oxygen atom which are bound by a covalent bond to form a polar molecule. This is because of its shape because they share those electrons with the oxygen atom, the electrons have a tendency to to stay close to the oxygen atom and the external side of the hydrogen atom tends to be positively charged. The oxygen atom has eight electrons. A lot of those tend to stay away from the hydrogen atoms, and cause the outside of the oxygen atom to have a negative charge (Triangularwave, 2015). It is also the only substance to occur in all three states of matter naturally. It…show more content…
Shade also directly correlates to the water temperature as the surface temperature of the water affects the actual water temperature. The factors affecting the temperature of a body of water are: air temperature, amount of shade, soil erosion increasing turbidity, thermal pollution from human actives and unfamiliar chemical reactions that weren’t occurring in the water before. This has various effects on the actual body of water. Factors which are affected: Resistance in organisms, fluctuation of the temperature stresses organisms, lowering their resistance to pollutants diseases and parasites (effectively changing water quality), metabolic rate of the organisms, rate of plant growth and solubility of dissolved oxygen (the lower the water temperature the more gases that can be dissolved in the water, i.e oxygen and animals and other organisms requiring high amounts of dissolved oxygen thrive on colder water). Another important parameter used to test the quality of water is the use of a pH scale. A pH scale is used to measure the acidity of a substance. The common scale consists of numbers 0 to 14 with 7 being the neutral point. The lower the number the more acidic and the higher the number the more basic. Water has a pH of 7 as it is a neutral substance. This scale can however exceed these numbers to above 14 or below 0. H+ and OH- ions can determine the pH value by their relative concentration. Water has a pH of 7 as it has equally the same
