The Many Uses of the Element Cobalt

As for metal, it has many uses. In fact, modern civilization has thrived off of things where iron is used like: buildings, car frames, bridges, and much more.

We use about 5.8 billion pounds of copper each year. We use copper for our money here in the United States. The copper is used in our pennies. Just in pennies we make about 13 billion pennies a year. All of that is copper. A penny weighs about 0.088 ounces. Another thing that we use copper for is electricity. Copper is a great conductor of electricity. Copper is able to take heat very well when running electricity because the conduct electrons. Copper is malleable and ductile. Since it is very ductile it allows us make wiring out of it. It is very well good at conducting heat so you will see it a lot in motor vehicle radiators and home heater systems. It is also used in air-conditioning. Copper is not really corrosive so that is why people will see it in pipes, water pipes. The only problem with the pipes made out of copper is that copper will bend and break really easy. Some copper is used in gun designs. They were also used for making swords and shields. Very few were made out of helmets but it was still used for that way back when. Also copper was well known for killing bacteria. So in the past they used it to treat wounds for patients because it could kill the bacteria. It was also used on the sides of ships to protect it from algae and other bacteria that may have harmed the boat. Copper has been used for a long time. It dates back to about ten thousand years

The purpose of performing the variety of tests that we did was to give more accurate results of what the unknown mineral was. By roasting the copper mineral, we obtained copper(II) oxide. This new sample came out of the crucible grayish-black. It was very brittle and full of cracks. This provided the percent composition that was necessary in finding the unknown mineral. When performing

First a few general informations: Copper has the chemical symbol Cu,an atomic mass of 63.546 and 29 protons. This means that it has also 29 electrons. If 63.546 is rounded to 64 and 29 is subtracted from this, Copper has 35 neutrons. The melting point of copper is 1085 C°.

During the Industrial Revolution it was used for mining, creating roads, and removing jagged places. Dynamite was also used in war and, to put it simply, terrorist attacks. Even though dynamite had good and bad purposes, it changed not only life in the Industrial Revolution, but the lives of everyone around the world. Dynamite set the way for explosives and construction devices today, and changed the way people fought wars. Before dynamite was invented the use of explosives in war was unheard of, and created a new way people fought

Key Concept 1.2. The Neolithic Revolution and Early Agricultural Societies II. Agriculture and pastoralism began to transform human societies. B. Technological innovations led to improvements in agricultural production, trade, and transportation. Pottery improved agricultural production because it gave a way to store a surplus of food.

The purpose of this lab was to determine the percent cobalt and oxalate by mass, and with that information, the empirical formula for cobalt oxalate hydrate, using the general formula Coa(C2O4)b.cH2O.

Nickel is the 28th element on the periodic table and is considered a metal. Its melting point is 1455 degree Celsius, and its boiling point is 2913 degree Celsius. The density for nickel is 8.90g and its atomic mass is 58.693. The atomic radius is 1.97 and its electron affinity is 111.537. Nickel is used for many things we use, drink, and many other things.

Tungsten is applied to different metals for a variety of uses. In applications where strong steels are needed, tungsten can be added in higher and lower quantities based on need to increase strength due to its increased durability. Some common uses for the material are electron television tubes, filaments in electric lamps, winding/heating elements for electric furnaces, missile/ high temperature applications, and high speed tool steels to name a

Cobalt is also used in batteries. Lithium-ion batteries have their limitations, however, as proven by the ill-fated Samsung Galaxy 7 tablets that spontaneously caught fire after a battery redesign. As a result, people have been searching for a better replacement. Silver, zinc, and other metals are more in demand. What’s driving the demand for more and better batteries?

Iron can be used for a wide range of resources in the contemporary world. It is the most abundant, least expensive, and most used of all metals. It is vital to human and animal life, and humans use it in a variety of devices to make life convenient. It is combined with other elements to make steel or other compounds for many commercial uses, the most common of which include making fuels, lubricants, automobiles, machine tools, hulls of large ships, building parts, machine parts, cooking pots and pans, cutlery, surgical equipment, and aircraft. Iron (III) “is used in the treatment of sewage, as a dye for cloth, as a coloring agent for paint, an additive in animal feed, and in the manufacture of printed

Non-ferrous metals were the first metals used by humans for metallurgy. Gold, silver and copper existed in their native crystalline yet metallic form. These crystals, though rare, are enough to attract the attention of humans. Less susceptible to oxygen than most other metals, they can be found even in weathered outcroppings. Copper was the first metal to be forged; it was soft enough to be fashioned into various objects by cold forging, and it could be melted in a crucible. Gold, silver and copper replaced some of the functions of other resources, such as wood and stone, owing to their ability to be shaped into various forms for different uses.

Cobalt was discovered by a Swedish chemist by the name of Georg Brandt. In 1735, Georg was trying to prove that certain minerals had the ability to color glass blue and was not due to bismuth but due to an unknown element (1). Since then, it has developed into a highly useful isotope.

Copper has many chemical properties that make it unique. The Atomic number of copper is 29. An Atomic number is a measure of the amount of protons in the nucleus of an atom. Protons are sub-atomic particles, which have a positive charge. The Atomic mass of copper is 63.546. The Atomic mass is a measure of how many neutrons and protons are in an atom. Neutrons are

into weapons or tools. Copper has been one of the most useful metals for over
