For example, silver nitrate formed a white precipitate when it was tested with ammonium chloride. In contrast, unknown 3 did not formed any precipitate with ammonium chloride. Ammonium chloride change the color of unknown 3 to a light green while the solution of silver nitrate and ammonium chloride was cloudy white solution. Likewise, the metal in unknown 3 could have been Calcium neither. Data and observation shows that calcium nitrate whether formed a white precipitate or did not react at all while unknown 3 formed an orange precipitate. Therefore, silver and calcium are not the two metal present in unknown

What is Calcium? The chemical element Calcium (Ca) is a malleable, ductile, soft metal. It's located in period four and group two of the periodic table. Calcium atoms have 20 electrons and 20 protons, there are two valence electrons in the outer shells. Its mass number is approximately 40.08. Calcium has four stable isotopes including 40Ca, 42Ca, 43Ca, and 44Ca; 97% of naturally occurring calcium is in the isotope 40Ca. Isotopes are atoms that have the same number of protons and electrons, but a different number of neutrons. In nature, calcium does not appear as a metal itself instead it appears in the form of rocks and minerals such as limestone, dolomite, and gypsum. Calcium can be found in countries such as Russia, China, USA, and France.

The element I chose to research is the element Titanium. Titanium’s symbol is Ti and is located Period and Group number four. Also, Titanium is considered a metal but does not have a group name. This element is usually found in the minerals rutile, ilmenite, and sphene. It also makes up 0.57% of Earth’s crust.

Calcium plays a very significant role in our bodies. Approximately 99 percent of the calcium in our bodies is stored in the teeth and bones. Calcium generates about two percent of our total body weight. Calcium is crucial in bone formation, keeping strong bones and teeth and is known for helping to prevent osteoporosis. Although calcium is mostly thought about in the bones and teeth, it also plays important roles throughout the body. The amount of calcium outside the bones and teeth may be small in comparison to what is inside the bones and teeth, but is very useful in many functions in the body. Calcium is required in functions such as the contraction

Calcium(Ca) is a soft, silvery-white, reactive metal. Its chemical symbol is Ca and it has an atomic number of 20. It is the fifth element on the periodic table and is the fifth most abundant element found in Earth’s crust. Calcium is an alkaline earth metal. Therefore, it reacts with water and when it comes in contact with air it creates a nitrate coating to prevent further corrosion

Muscatine, Iowa isn't the K9 capital of America, but all dogs matter. Every fluffy pup deserves a nice place to frolik and play with others of its own kind. Creating a dogpark in the heart of this city is just the right decision to livin it up.

Calcium is a chemical element with symbol Ca and atomic number 20. Calcium is a dull gray, silver solid under standard conditions. Calcium atoms have an electron configuration of (2, 8, 8, 2) and 2 outermost shell electrons. Calcium is in group 2 and period 4 of the periodic table. Calcium commonly forms the cation Ca2+ by donating 2 electrons, reaching a stable electron configuration. Calcium is an alkaline earth metal.

The formula CACO3 is very common in natural such as limestone cave, animal’s bones. Normally, the cement production and agriculture have deployed this component. The formula CACO3 is utilized to enforce the strength of cement in the company. Increasing the strength is one of a good property of eggshell. The other one is raising a plant and garden. Most fertilizer companies produce a various type of fertilizer to blend calcium in their products for encouraging vigorous plant growth. calcium boost fro

Did you know that calcium is the fifth most abundant element in the earth's crust? Calcium has been used for decades for creating statues and other things. It was not till 1808, when Sir Humphrey Davy isolated the element. Calcium has a greyish silverish color, and is rather hard. It can be found in many things, for example bones, teeth, shells, and in various minerals such as limestone, gypsum, and furite. It is classified chemically as one of the alkaline earth metals, and is rather reactive. Calcium is used for many things like as a building material, but one of the most important thing we use it for our bones. So make sure you drink your milk!

In Tinorgea the government will have their own building called the Governmental Building of Tinorgea. In the building will be the dictator and his family. The dictator will be chosen by the previous dictator. The new dictator chosen must also be approved by Head of Security which is also chosen by the dictator at the time. To make a law, the dictator will first send a request to the Head of Security which will then approve the law it will then go back to the dictator and will be sent out for a public vote. The public will vote on the law and the majority of the population vote decides. To keep our citizens safe, we will have Watch Towers every one tenth of a mile. Inside the tower will be Security members that are armed with small guns. The

Introduction: The purpose of this lab was to find the relative solubilities of some salts of the Alkaline Earths and use that information to find the order which they appear in the periodic table; also use that information to efficiently find an unknown alkaline earth halide. Also to find the relative oxidizing powers of the Halogens given and using that information finding the order of the Halogens in the periodic table; also use that information to efficiently find an unknown Halogen.

Some minerals are used by our body in large amounts to form various structures like bones or teeth. Minerals like this are known as bulk minerals. Calcium is one of the better known bulk minerals. Another category of minerals are trace minerals. Trace minerals are used within the body in very small quantities. However, they are still just as important to good health as bulk minerals. Unfortunately, science didn't recognize the usefulness of trace minerals for many, many years. In fact, it was even thought that not

Calcium phosphate is found in cow milk. Seventy percent of bone and ninety percent of tooth enamel contains a calcium phosphate mineral known as bone mineral or hydroxyapatite. Calcium phosphate is often used to prevent and treat calcium deficiencies. Calcium phosphate contains 40 percent elemental calcium, tied for the highest of any calcium
