to see which chemical kills the plants faster. It is hypothesized that ammonia will kill the radish plants faster than vinegar or both vinegar and ammonia combined. BACKGROUND INFO: AMMONIA Ammonia is a chemical compound which is made up of nitrogen and hydrogen‚ the chemical formula for ammonia is NH3. This chemical is the foundation of most

vessels that gradually become narrower. At the same point‚ the embolus will block a small artery and cut off the blood supply to a particular area of the body. ▪ Nitrogen Narcosis is an affect on the brain of gaseous nitrogen that occurs to divers who go below 100 FSW‚ due to the laws of partial pressures. It is the gas that causes nitrogen narcosis through the affect of Dalton and Henry’s Law and it is the gas that causes decompression sickness on ascent from depth with reduction of pressure. ▪

much oxygen causing them to find it difficult to breathe. Breathing into a paper bag helps them hypoventilate to the point where they are calmed and can breathe at a normal rate again. This is because you exhale 17% oxygen‚ 4% carbon dioxide and 89% nitrogen so rebreathing this air will help you inhale more carbon dioxide and helps it to be quickly added back into the bloodstream. This restores the balance of gases in the blood stream which in turn slows breathing rate and gets it back to your steady

Etosha: Place of Dry Water Etosha is an ecosystem that contains many interacting species of organisms and their physical environment. As the seasons change‚ the temperature and climate affect the biotic and abiotic factors. Biotic factors are the living organisms that are affected by abiotic factors. Abiotic factors are the non-living or physical factor that directly affects the living organisms. Etosha displays all type of biotic and abiotic factors as the seasons change and the rainy seasons come

Haber-Bosch Process) The Haber process is the process for converting nitrogen and hydrogen from natural gas into ammonia. Control & Click to follow link. The Haber Process PPT.ppt Questions to Answer Questions that should be answered by the content of your research project: 1. Describe the process you researched‚ including its uses in various industrial or health fields. I chose to research The Haber Process. It combines nitrogen from the air with hydrogen that comes from natural gas‚ into ammonia

growth are classified into two groupings‚ macronutirents and micronutrients. Macronutrients are those that are needed in very large amounts‚ and whose absence can do a great harm to the development of the plant life. These nutrients include calcium‚ nitrogen‚ phosphorus‚ and potassium‚ and are very sparse in most soils‚ making them the primary ingredients in most fertilizers. The other‚ more common macronutrients are called secondary nutrients‚ as they are not of as much importance. Micronutrients‚

Bio Cement The project aims at attaining high durability of concrete and gaining high strength of cement. We plan to make use of bacterial species which can hydrolyze the enzyme Urease efficiently to produce microbial concrete. Such bacterial are known to produce calcium which is useful in giving strength to cement. We are working in 2 stages. Stage 1: Here we check the effect of bacterial solution on cement mortar and along with that we check the effectiveness of the bacterial solution

zero (-459 degrees Fahrenheit‚ 0 degrees Kelvin‚ -273 degrees Celsius) to liquid nitrogen temperatures (-321 F‚ 77 K‚ -196 C)‚ they have no electrical resistance. The temperature at which electrical resistance is zero is called the critical temperature (Tc) and varies with the individual material. For practical purposes‚ critical temperatures are achieved by cooling materials with either liquid helium or liquid nitrogen. The following table shows the critical temperatures of various superconductors:

from naturally occurring substances‚ and include by-products or waste remains of the animals. Dead plants and dead animal remains are also often used as fertilizers in organic farming. They are naturally chemical-rich and contain high amounts of nitrogen‚ phosphorus and potassium (NPK). The main difference between a chemical and an organic fertilizer is that the former come out of a lab and the organic one comes from living beings. A chemical fertilizer is synthetically prepared to include the

Phosphorus is used to measure the relative acidity of solutions such as water. The range for pH is measured in 0-14 scale. 0-6 is unhealthy‚ 7 is neutral‚ and 8-14 is healthy. Nitrogen is an element that helps invertebrates survive because it has special proteins that help them grow. Nitrogen then enters as ammonia. The range of nitrogen ammonia should be between 1.3 and 2.2 mg/L at all times.
