Abundance of the chemical elements

threatened by these problems. The chemical compound in the coastal environment has to be regularly monitored to protect both human and ecosystem in the coastal area. The environment pollution monitoring using mussels was established in North America coastline and estuarine. It’s followed by other countries like Australia, Japan, France, Taiwan, India, and Mediterranean (Goldberg, 1975) in (Widdows and Donkin, 1992). The environmental tolerance ability, abundance, population stability,…

Kishan Patel Section: 008 Pattern: Calcium levels in the soil controls soil pH and species richness within a community Hypothesis 1: Calcium levels in the soil controls soil pH. Prediction: An increase in the calcium levels in the soil will make the soil less acidic. Reasoning: Calcium exists mainly in the soil as exchangeable cations (ca^2+) associated with basic anions, which reacts with soil acidity (H) to neutralize it. Analytical approach: Regression Independent variable: Calcium levels…

would not have occurred” (Martin and Russell 2006). This is because hydrothermal vents are a constant supply of inorganic compounds of which are vital for prokaryotic autotrophic organisms. They provided a “sustained source of chemical energy by virtue of the CO2/H2 chemical potential” (Martin and Russell 2006). There are arguments that hydrothermal vents are too hot in order to create a suitable environment for the first organisms, however it has been shown that some ‘Lost City’ vents have an…

XMM Newton:- The XMM-Newton (X-ray Multi-Mirror Mission or High Throughput X-ray Spectroscopy Mission) is an orbiting X-ray observatory launched in December 1999 by ESA (European Space Agency). ). XMM-Newton is the biggest satellite ever built in Europe. It is used for the detection of soft portion of the electromagnetic spectrum (100 eV to 12 keV).Using its large collecting area and highly eccentric orbit, it is making long observations of X-ray sources with extremely high sensitivity. It is…

Introduction In our society, people may think Mars would be easier to understand. Similiar to Earth, Mars may has ice and water in its atmosphere, different wheather in seasonal, and other recognizable features. However, conditions on Mars vary wildly from what people know on our own planet.Solar system has influenced numerous cultures effecting legends, religious beliefs and at the beginning of the 21st century. Mars Odyssey have long been achieved which is a part of Mars Exploration…

Moles 1.How is molar mass calculated and why is it useful? Molar mass is calculated by going to the periodic table finding each mass of each element in the compound then adding them all up based on how many of those elements are in the compound. 2.Define a mole in chemistry and give 3 examples equivalent units that are used in chemical calculations. Mole is considered the unit for amount in chemistry other units that are equivalent are atoms, formula units, and molecules. Gas Laws 3.How is the…

periodic table had been a key factor in many ways to finding new elements, like scandium, silicon, and neon. It has shown new ways those elements could help us by predicting certain elements reactions. While Dimitri Ivanovich Mendeleev is considered to be the creator of the periodic table, there were many contributions that helped the creation of the useful graph be achieved. Between 1817 and 1829 Johann Dobereiner was grouping elements with similar properties into groups of threes, which he…

derived from decaying plants and animals that have been fossilized over millions of years. There is more to them than that however they are also hydrocarbons comprised primarily of the following elements: carbon and hydrogen and some sulfur, nitrogen, oxygen, and minerals. Different combinations of these elements are used as a fuel for our everyday lives. This paper’s purpose is to explain some of the chemistry behind the use of these various fossil fuels as well as just some general properties…

There are 2 types of strengths that materials can be tested on: Comprehensive strength and Ultimate Tensile strength. Ultimate Tensile strength is measured by how much stress can a material withstand, while being stretched or pulled apart before breaking, while comprehensive strength is how much van the material resists while being pushed in (together). There is also a Yield Strength- the point at which the material starts to slowly break and cannot come back to it’s shape. Before the yield…

This is shown in the balanced chemical equation by the products of water and the solid copper chloride. The observation of the liquid turning clear represents the water and seeing the particles represents the precipitate. The yield of copper chloride is 1.49 grams. This demonstrates the…
