Course # Student name / Names of members of group Date: Exp # : Estimating the effects of acid rain Introduction: Precipitation that measures a pH value below 5.6 is generally considered as acid rain. Burning fossil fuels is the main reason for the elevated levels of gaseous oxides in a polluted atmosphere that in-turn forms acid rain. Gaseous oxides such as that of carbon, sulfur, nitrogen and phosphorus could dissolve in water to form an acidic solution. A generalized reaction sequence on the formation of acid rain is as follows; One of the determinants of clean water in the natural environment is its alkalinity. Alkalinity can be defined as the capacity to neutralize acids.
Sulfuric Acid is a strong acid that exists as a colorless oily corrosive liquid and is made by reacting sulfur trioxide with water. This is most commonly found in batteries, manufacture of fertilizers, explosives, detergents, dyes and other different chemicals. Sulfuric Acid is very dangerous to humans as it can cause respiratory tracts of humans and other animals while doing some major damage to plants that helps provide oxygen for us. Ground-level ozone is a secondary air pollutant formed when sunlight triggers reactions between nitrogen oxides and volatile hydrocarbons. If a human inhales ground-level ozone it can cause chest pain, throat irritation, and congestion.
This experiment was completed with the purpose of testing and discovering the effects different contaminants have on water and to hypothesize the possible effects contaminated water could have on the human body based on research and readings of different scholarly sources. This investigation will also determine if there are any differences in taste and compositional makeup between tap water and bottled water. The pollutants used in this experiment are oil, vinegar, and laundry detergent. For my hypotheis for this experiment, I believe that the oil and vinegar will have a more negative effect on the water and the laundry detergent will have the least negative effect, which I believe will only give the water a more soapy aroma. For the difference in quality between tap water and bottled water, I believe that the bottled water, in this case Dasani and Fiji, will be a lot purer and not have as many contaminants than the municipal tap water.
Water Quality and Contamination Report 1 Schrita Scott Water Quality and Contamination SCI207: Dependence of Man on the Environment Instructor Carrie Myers February 25, 2014 Water Quality and Contamination Report 2 Water Quality and Contamination Introduction: When it comes to water quality and contamination, first and foremost ground water is present below the surface in porous rocks and is prone to contamination by natural and human activities. Large amounts of chemicals like soap, detergents, fertilizers, pesticides, and pharmaceutical are often times discharged into fresh water aquifers almost daily. These contaminants leak into the soil in which it then dissolves into ground water. Different contaminants have different rates of solubility and degradation once they reach the underground water table, either by simple flow or by the downward movement of rain water. The ground water may become contaminated with both organic and inorganic substances which may include heavy metals like Cadmium, Chromium and Nickel, etc.
In Partial Fulfillment of the Requirements of Science 9 Submitted by: Macam, Victoria Liz C. Escabarte, Chrystine Hace A. Navarro, Carl Louie T. Abstract: The researchers came up with the problem, “Can vitamins affect the growth of plants?” Many investigations were made regarding this problem yet the researchers wanted to clarify everything and tested the effectiveness of the vitamins with their own eyes. The researchers arrived with this problem because they wanted to know if there is a difference between organic and inorganic fertilizer and human vitamins. Lastly, the researchers wanted to help the farmers in providing a safer and more effective way of having healthy plants. Vitamins are important for the growth of plants. Based on other investigations, vitamins which are made up of organic compounds can help plants grow by providing them with essential nutrients.
The sexually transmissible disease gonorrhea has become increasingly resistant to treatment with antibiotics. What is the most likely scientific explanation? a) The gonorrhea bacteria learned to avoid antibiotics b) The gonorrhea bacteria changed their genes when they sensed antibiotics c) Antibiotic-sensitive gonorrhea bacteria died out, but antibiotic-resistant gonorrhea bacteria have flourished and persisted d) The antibiotic increased the mutation rate in the gonorrhea bacteria e) Both b and d 26. Which statement best describes the relationship between plants and animals on earth? a) Plants produce O2 and sugars from CO2 b) Animals produce CO2 and H2O from sugars and O2 c) Plants produce O2 and sugars and animals produce CO2 and H2O d) Animals produce O2 and sugars and plants produce CO2 and H2 27.
Research question: Will the level of acidity of the rain have an effect on the corrosion of limestone, as measured by change in mass of marble chips in a beaker? Introduction: Acid rain is any form of precipitation due to excess or elevated levels of hydrogen ions. It is also a process by which acid particles leave the atmosphere. Natural rain has a pH of 5.6; this is due to the presence of carbonic acid by the mixture of carbon dioxide dissolved in water in the atmosphere. H2O + CO2 → H2CO3 The carbonic acid molecules immediately dissociate in water to form hydrogen carbonate ions: HCO3−, and hydronium ions, H3O+: H2CO3 + H2O → HCO3− + H3O+ The deposition of acid like sulfuric and sulfurous make rain water acidic this is from the sulfur
It has to be considered the negative correlation between the levels of salt stress and crop growth rate. Reduced plant growth is also caused by stomatal closure involved in the decline in photosynthesis and limited CO2 uptake. The response to salinity consists of numerous processes that must function in coordination to alleviate both cellular hyperosmolarity and ion disequilibrium (Hasegawa et al., 2000). Plants have evolved mainly four strategies to fetch tolerance under high salinity; i) ion homeostasis; ii) osmolyte biosynthesis; iii) transcriptional factor and salt related genes regulation; iv) hormonal regulation (Vaibhav and Gothandam,
