Chemistry is used in everyday life, whether it is known it or not. As students, it is important to know how elements contribute to everyday life. Some elements are helpful, while others are deadly. Calcium is one of those elements. It is important to know how it was discovered and what its properties are. It is also necessary to know what others have researched about calcium. Finally, all this knowledge would be nothing without the benefits of calcium. Because of its importance, it is vital to know who discovered the element calcium and what its properties are. Calcium was used by the Romans to make lime. But it was isolated and accepted as an element in 1808 by Englishman Sir Humphrey Davy. He discovered it by studying the limestone and marble used in the past. Calcium is an alkaline earth metal; it has the symbol Ca, its atomic number is 20, and its atomic mass is 40.08g. Calcium is a silver-white, soft metal, but it is …show more content…
There are two areas that calcium is used the most, food and manufacturing. First, calcium is used in the food industry in many areas. It is found in dairy products, dark leafy greens, almonds, and soybeans to name a few. Consuming calcium-rich foods can help people lose weight, help fight cancer, and help decrease the risk of type 2 diabetes. These are just a few of the many uses of calcium in food products and their benefits. Calcium is also used in the production of construction materials. Calcium carbonate, also known as limestone, is used for making cement. Live Science states in their article on calcium, “Gypsum, or calcium sulfate, is used in making plaster and also "plaster of Paris," a heavy white powder that, when mixed with water, hardens into a cast to set fractured bones.” They also say that calcium in its purest form can be used as a reducing agent in preparing other metals. These are just a few of the many uses for
Calcium helps make bones strong and dense. Calcium is not made in the body so the body has to get it from the bones. When calcium is low bones will release less calcium into the blood stream.
Calcium is the 20th element of the periodic table. It is a metallic element that is greyish-silver in colour and has the atomic symbol of Ca. It is a group 2 alkaline earth metal and is the 5th most abundant element by mass in earth’s crust. It is also reactive with water and is relatively soft. It is an essential element for organisms, and is major material that is used in the materialisation of teeth, bone and shells. It is also the most abundant metal located within animals.
Strontium was discovered by Adair Crawford, an Irish chemist, in 1790 while studying the mineral witherite (BaCO3). When he mixed witherite with hydrochloric acid (HCl), he did not get the results he expected. He assumed that his sample of witherite was contaminated with an unknown mineral, a mineral he named strontianite (SrCO3). Strontium was first isolated by Sir Humphry Davy, an English chemist, in 1808 through the electrolysis of a mixture of strontium chloride (SrCl2) and mercuric oxide (HgO). Strontium reacts vigorously with water and quickly tarnishes in air, so it must be stored out of contact with air and water. Due to its extreme reactivity to air, this element always naturally occurs combined with other elements and compounds. Strontium is very
Vitamin C is a necessary vitamin for the body to carry out its functions properly. It is also known as ascorbic acid. It is a water-soluble nutrient that is found in some foods. It acts as an antioxidant in the body which helps to protect cells from the damage caused by free radicals, which are formed when our bodies convert the food we eat into energy. The body needs vitamin C to make collagen which is the protein required in wounds, healing. Moreover, vitamin C promotes the absorption of iron from fruits and vegetables and helps in promoting the immune system. Vitamin C is also important to protect our body from cardiovascular disease, prenatal health problems, eye disease, and skin wrinkling. We can obtain vitamin C from food and other sources.

It was discovered by Sir Humphrey Davy in England, in 1807. Sir Davy was able to isolate potassium using electrolysis. Potassium was the first metal isolated by this procedure. Today, it is still not found free in nature. It is obtained by electrolysis of chloride or hydroxide.
As a chemistry major, math altogether is important in understanding my major and its curriculum. Calculus is a subject that many have difficulty understanding, including myself. Understanding derivatives is very necessary because it is the basics of calculus and modern mathematics. What is differentiation? Differentiation is the algebraic method of finding the derivative for a function at any point. (Wyzant)
Out of the sources of calcium available, dairy products most aptly provide the necessary calcium with the least amount of side effects. Using dairy products as a calcium source cuts out the need to research which type of calcium is being supplied because all dairy products contain elemental calcium (Got Calcium?). A benefit of elemental calcium is an increased ability to gauge how much calcium is being absorbed (Calcium Supplemental Guidelines). This is because the elemental calcium in dairy products is more easily absorbed (Got Calcium?) Dairy products’ calcium is also less susceptible to complications with other ingested substances such as food or medications (National Osteoporosis Foundation). Removing these possible complications also removes some of the concern of short-term health risks associated with calcium. Studies have also indicated that elemental calcium does not increase some long-term health risks as calcium citrate or calcium carbonate (which are both found in calcium supplement pills) might (Harvard School of Public Health). All of these benefits make dairy products a safe and reasonable choice for supplying calcium needs.
Gypsum is quite useful and some interesting facts about it is that it can be added to certain breads and doughs as a calcium source or as a type of baking additive considering that it is 100% safe for consumption. It can be used as a fire retardant, be used like modeling clay for teeth replacements, and so much more. It is a versatile mineral and has been around for thousands of years. Throughout the years, more uses for it have been found and the material is being utilized even more as the years progress. (Gypsum: the "Magic" Mineral Indefinitely Recyclable,
Ca(NO3)2 and Na2(C2O4) are combined to produce calcium oxalate stone samples. Next Ca(NO3) and sodium phosphate are utilized to synthesize calcium phosphate stone samples. For the synthesis of the calcium oxalate stones, 11 grams of Ca(NO3)2 is dissolved in 225mL of DI water. 8.00 grams of Na2(C2O4) is dissolved separately in 200mL of DI water. The two aqueous solutions were mixed separately in order to ensure their complete homogeneous transition. Once each solution is completely dissolved, the aqueous solutions of Ca(NO3)2 and Na2(C2O4) are mixed together to form the precipitate , which produces the Calcium oxalate stone
Sodium has an atomic number of 11 and a mass of about 23g. It is a silvery white-metallic element classified under the alkali metals. Sodium has been known since early times and was used by the people of Mesopotamia and Egypt to make glasses. Sodium is the sixth most common element found on the earth. It is usually not found in nature but more often in compounds such as salt (NaCl). Sodium conducts heat and electricity easily.
In 1803, John Dalton published a list of elements. He tried to make a system to make the elements easier to remember and write. The original ...
Homework offers multiple benefits for real life. One benefit of homework is that it helps the student develop essential skills. While homework may seem like a tedious task, it can help a student comprehend the material. Homework is necessary for more than just a grade; it is an assignment that teaches you valuable life skills. According to “Do students have too much homework?”, homework should lead students to be better at taking what they know and applying it to a certain task. Students tend to portray homework as something that they have to get done without knowing the value that lies behind it. Homework enables the student to recall a certain problem and apply it to another distinctive situation. According to “Do students have too much homework?”, applying knowledge is the most important. Learning is definitely important but what students do with the facts that they learned is essential as well. Applying knowledge allows the students to take a simple fact and relate it to a grander scheme of things. Relating what they know will enhance their creativity and let them see behind the lines of how everything connects.
Throughout my school career I have always loved chemistry. In Chemistry there was always a sense that there was more, there was always something new and exciting to be discovered and theories to be proven (or even disproven). Chemistry was the main subject with a real practical aspect to it during school and it is this, along with my genuine fascination with the subject, which fuels my desire to study it further.
Chemistry forms the dispersible foundation of disciplines such as biology, medicine, and material sciences. Future studies show an accelerating change in the technology through history. What is chemistry? Wikipedia defines it as a branch of physical science and is the study of the composition, properties and change of matter. It has been said that chemistry is also called the central science because it builds bridges to the other natural sciences. The history of chemistry goes back into the ancient times, back as far as about 1000 B.C. Examples of chemistry would be taking metal from ore or pottery to glazes. The art of chemistry is the matter of changing things into another. What is the point of studying chemistry? Because we use all the time, especially when we are cooking. If you know how to use chemistry to your knowledge, then it can help you make everyday choices. There are many people who work in the field of chemistry. People from doctors to truck drivers. People often...
