In order to properly grow, plants need certain macronutrients and micronutrients. They need the macronutrients: nitrogen, phosphorous, potassium, calcium, sulfur, magnesium; and the micronutrients: boron, chlorine, manganese, iron, zinc, copper, molybdenum, and nickel. (3). Fertilizer enhances the growth rate of plants. Fertilizer adds nutrients and modifies the water retention and aeration of plants. Fertilizer contains three main macronutrients: nitrogen for leaf growth; phosphorus for the…

nutrients, which include Calcium (Ca), Magnesium (Mg), and Sulfur (S), are found abundantly in the soil. In contrast to macronutrients, micronutrients are essential for plant growth but are only needed in very low quantities. The micronutrients are: Boron (B), Copper (Cu), Iron (Fe), Chloride (Cl), Manganese (Mn), Molybdenum (Mo) and Zinc…

standard silicon based photovoltaic cell will have a thin, negatively charged phosphorus-doped silicon wafer on top of a positively charged thicker boron-doped silicon layer. Excess electrons from the phosphorus-doped silicon layer move to the electron deprived boron-doped silicon layer, resulting in the phosphorus-doped layer becoming positive and the boron-doped layer becoming negative. This switch creates an electrical field over the cell that acts as a medium for current (Morris). The…

Chemistry Honors Mrs. Moreno Period 5 INTERPRETING THE PERIODIC TABLE Partner’s name: Faranak Hajikhan, Pablo Moncada, Albina Contreras and Karla Santos Title: Interpreting the Periodic Table Date: 12-18-14 Subject: Honors Chemistry / Period 5 Introduction: The periodic table is a table of the chemical elements in which the elements are arranged by order of a atomic number. The periodic table also has a special name for its vertical columns. Each…

who consume less than 500 mg a day may be inclined to have low bone mass. Calcium supplementation may help to sustain preserve come bone structure, but it is not clear weather this helps to inhibit fractures. Habitually sub-par intakes of Vitamin D, Boron, Vitamin K, Vitamin B12, Fluoride, magnesium, folic acid, and vitamin B6 and folic acid may put individuals at higher risk of osteoporosis. On the latter, abnormally high intakes of alcohol, sodium chloride, caffeine, and protein may also…

One action that was taken was using aircraft vehicles to pour sand and boron from debris from the reactor. The intentions of the poured sand was to smother any remaining fires as well as prevent any further release of nuclear material. The boron was used to prevent any further nuclear reaction. After a few weeks passed, the response crew started to construct a concrete unit called a Sarcophagus to cover the…

Chlorine is an element that consists of 17 protons, an average of 18.5 neutrons and 17 electrons. It has an atomic number of 17, and an average nuclear charge of 35.5. There are 2 isotopes of chlorine that are 35Cl and 37Cl. 35Cl has an atomic mass of 35 and a natural abundance of 75%. 37Cl has an atomic mass of 37 and a natural abundance of 25%. The average atomic mass or nuclear charge equates to 35.5. Both of the isotopes have the same atomic number. (BBC Bitesize. Atoms and the periodic…

1. What is the forbidden gap in semiconductors? One electron volt (eV) 2. At absolute zero temperature, semiconductor behaves as Insulator 3. Define electrical conductivity. Electrical conductivity is the ability to conduct an electric current. 4. What are the two types of charge carriers in semiconductors? Electrons and holes are the two types of charge carriers in semiconductor. 5. Define charge carrier. Charge carrier is a particle, which carries electric charge or electric current from one…

The Big Bang theory is a theory scientists use to explain the creation of the universe. According to this theory, the universe was concentrated into a single point 13.7 billion years ago. This theory states that the universe started as a singularity. Time began when this single point exploded causing the expansion of the universe. This expansion formed matter, energy, space, and time. In 1915, Albert Einstein applied his theory of General Relativity to how the universe began. General Relativity…
