than distilled water‚ which has a pH of 7. How does temperature/the presence of salinity affect the oxidation rate? Pyrite oxidation generates O2 and produces heat. Due to this‚ the acidity and temperature of the surrounding soil/solution will affect the overall reaction rates (4). Biological oxidation only occurs between 0oC and 55oC with an optimum range of 24oC – 45oC (4)‚ but chemical oxidation can happen at a much higher temperature. It is predicted that the PASS will oxidize at a much faster

is where photosynthesis occurs. Respiration can be defined as the oxidation of the end products of glycolysis with the storage of the energy in the form of ATP. Cellular respiration occurs when oxygen is available‚ and the products are carbon dioxide and water. There are three main pathways in the cellular respiration process. These are: pyruvate oxidation‚ the citric acid cycle‚ and the respiratory chain. Pyruvate oxidation in eukaryotic cells occurs inside the mitochondrion in the inner membrane

Introduction A. Background of the Study For us‚ a house is a place of residence. It is usually a place in which an individual or a family can rest‚ store personal property‚ and prepare food. In able for the house fulfills its function‚ we need to eliminate some factors that disturb us in doing these things. Example is the insects. One of the easy ways to prevent insects is to use insect repellant. This is the reason why the researcher decides to make a liquid insect

Greenhouse gas Greenhouse effect schematic showing energy flows between space‚ the atmosphere‚ and Earth’s surface. Energy exchanges are expressed in watts per square meter (W/m2). A greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect.[1] The primary greenhouse gases in the Earth’s atmosphere are water vapor‚ carbon dioxide‚ methane‚ nitrous oxide‚
