Disadvantages Of Engineering Materials

For the industries the larger equipment is used which is made up of metal or ceramics.

* Copper, gold and aluminum are all alloyed with other metals to make them harder.

New technologies were used such as alloying and casting metals for tools, weapons, and luxury goods.

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.

2. If the mineral is non-metallic, decide if it is light or dark in color.

Chemical equilibrium is a dynamic state where the rate of the reverse reaction is equal to the rate of the forward reaction. The chemical reaction is still occurring however the rate of reverse reaction is matching the rate of forward reaction hence the concentration of reactants (〖Hb〗_((aq) ) + O_(2 (g))) and products (HbO_2) no longer change, resulting in an equilibrium. (b) Which direction will equilibrium shift if the O_(2 ) concentration is increased?

Nonmetallic properties tend to predominate for elements at the far right portion of the table.

Aim: To classify unknown substances according to their structure type and to observe how the structure of materials affects their uses.

Architects turn to zinc for its long, maintenance-free life and adaptability to various design styles ranging from traditional to modern. It is at the forefront of contemporary design. Zinc is also a major prospect to science and technology. Battery-powered laptops now can use a zinc-are battery, which provides more than 12 hours of usage on a single charge. That's almost ten times the runtime of the original battery. The battery can also give cars enough power to reach speeds up to 120 mph. A high-purity alloy of zinc and copper is used in water purification. Zinc is also the key ingredient in a new hi-tech tape that is helping law enforcement officials around the world conduct safer and more reliable undercover work. Consuming more than 40,000 tons annually, the toy market is also an important user of zinc.

The periodic table is a table that categorises and displays all of the chemical elements. It is made up of groups, periods and blocks. A group (also referred to as a family) are the columns of elements, there are 8 groups. The elements in each family have similar but not identical properties and they all have the same number of outer electrons. E.g. lithium (Li), sodium (Na), potassium (K) are all soft, white, shiny metals because they are all members of group 1. A period is each horizontal row of elements, there are 7 periods. In a period, the elements are not alike in properties, the first element in a period is always an extremely active solid, and the last element in a period is always an inactive gas. Properties change greatly across a given row. Each new period represents the next shell which electrons fill. A block is a region of the periodic, there are 4 blocks: S, D, P and F.

Theses are exported for the iron that they need, and gold and silver after that.

An unknown material can be determined by using simple chemical tests and separations which is called as inorganic qualitative analysis. The separation of cations depends on the difference in their propensity to form precipitates. Separation scheme is used to classify cation into five groups on the basis of their physical and chemical behavior opposed to some reagents. Classification is based on whether there is formation of precipitates or not when metal cations react with the reagent. The five groups of cations and the characteristics of these groups are as follows:

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

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