Carbonate

not discovered as a metal until 1808.(Helmenstine, 2015) It is hardly found in the elemental form, however it is easily found all over the Earth often in the form of rocks and minerals such as limestone also known as calcium carbonate, dolomite called calcium magnesium carbonate, and gypsum which is calcium sulfate. Calcium is recognized as the fifth most common element in the Earth’s crust. It is about the eighth most sufficient element found in the ocean.(Nelson, 2015) This element is the…

shell was dissolved, and the egg got larger. The reason the shell dissolved is because vinegar contains acetic acid, this breaks apart the calcium-based eggshell creating two byproducts. One byproduct is carbon dioxide from dissolving the calcium carbonate crystals in the shell. The second byproduct is the calcium…

minerals can be beneficial, as humans need minerals to survive. However, water hardness begins to cause problems when it comes its constant use in the home and in appliances. For instance, when the water is heated, it forms solid deposits of calcium carbonate. This type of mineral build-up can decrease the lifespan and efficiency of…

replacing bone and mimicking their structure for, various applications. When looking at biological materials, to determine their effectiveness as a scaffold or sufficient structure for various other uses, often they are tested for their resistance to fracture. This is referred to as fracture propagation. Bamboo Bamboo is well known for its sufficient mechanical properties, and great flexibility. It also has great fracture toughness. Bamboo is considered to be a bio composite, meaning it…

BEST DISHWASHER DETERGENT FOR HARD WATER Firstly we need to recognize what hard water is, hard water is a water that has high mineral substance. Hard water happens when groundwater grabs minerals as it moves through rock and soil. It most normally grabs salts like magnesium chloride and calcium chloride. At the point when hard water is utilized to wash your dishes, it might turn out looking more regrettable than when they went in. Hard water leaves your dishes spotted and can even keep your…

As it can be seen in the previous figure, the Bubble Column PBR is a simple conceptual design. The figure simply illustrates the basic flow in the column. The gas enters the bottom of the column through a diffuser causing the gas to break into thousands of small bubbles making it easier for the algae to absorb the carbon dioxide in the gas. Once the algae have consumed as much carbon dioxide as it can, it releases oxygen in the form of gas, which leaves the column through the opening in the…

Purpose What makes the best bubble solution? In order to make a best bubble solution, I have to use detergent, corn syrup, water, and glycerin. By the best, I mean a mixture that creates a solution which will last long. Acknowledgments I would like to thank everyone who helped me make my project successful. First of all, I would like to thank my teacher Mr. Mackey’s help. He provided the instructions and explained how to do an essay and a poster board. Secondly, I would like to thank you my…

Discussion: In this section the results of the degree of water hardness of the water samples of this group using the two primary methods EDTA and AA will be discussed and analyzed in terms of which sample is exhibiting a high degree of hardness and which sample is considered to have a small water hardness value compared to other samples, and test the hypothesis and prediction of the water samples being tested. According to the results obtained and calculated the water sample that has a high…

SHAKEN OR STIRRED – WHAT’S THE BEST FINISH FOR MARBLE FLOORS Polished, Honed, and Tumbled Finishes for Marble Floors Selecting the right finish for your marble flooring is a critical factor when deciding on the look and feel of the floors throughout your home. Overall aesthetics are important to your design, but the finish for your natural stone may be more appropriate for certain areas of the home depending on traffic and nature of use. Marble is a fantastic choice for floors. In addition…

Marble is a metamorphic rock that can be found in lots of places, this rock has many uses in our everyday life. This rock can be found in many common household items. There are many different colors of marble that are found all over the world. Colorful marble is discolored due to how it was formed. When marble is formed from a limestone that has few impurities, the marble turns white. If the marble contains clay minerals, iron oxides, or bituminous minerals, the marble will turn a different…
