Petroleum and fossil fuel area unit organic compound compounds. fossil fuel may be a complicated mixture of liquid hydrocarbons, a compound containing gas and carbon, that is created naturally in underground reserves in matter rocks.
2. Fossil Fuel
Natural gas may be a mixture of alkanes with compositions looking on the supply. Generally, it contains eightieth gas (CH4), seven-membered hydrocarbon (C2H6), 6 June 1944 gas (C3H8), four-dimensional alkane and isobutane (C4H10), and three pentane (C5H12).
Tin ore is that the results of weathering granite rocks, tin is one in every of the foremost vital minerals wont to turn out electronic devices like smartphones, computers, TVs, and so on.
Coal has many classes supported the part of carbon contained in this, there area unit styles of hard coal (carbon content 86-98%), hydrocarbon (carbon content 68-86%), Sub-bituminous (less carbon content and plenty of water content), coal ( carbon content of 35-75%, incorporates a brown color and is thought to be soft and light), humate (porous with water content up to 75%).
5. Iron Ore
Iron ore within the kind of stone or minerals (sand) that through the extraction method will turn out iron metal. metal metal will then be used as a main material for steel.
Gold is one in every of the metals that area unit classified as beginning metals due to their corrosion resistant and erosion properties. Gold is additionally a valuable metal as a result of it's a comparatively high artefact and trade worth.
Copper may be a kind of metal with the image element atomic number 29 (Cuprum). Pure orangeness copper. Copper is wide used as a conductor of electricity and warmth, building materials, and additionally as a part of many styles of metal alloys / alloys, for instance for jewellery alloys manufactured from alloy, for creating coins, and so on.
Diamond is one in every of sorts|the kinds|the categories} of rock type minerals that area unit far-famed to be terribly exhausting. typically diamond is employed for the bit of a machine besides being employed for jewellery with a really high sale worth.
Nickel may be a metal that in its use is mixed with iron to be rust resistant and become steel, mixed with copper to become brass and bronze.
Manganese may be a black metal mine that's sometimes employed in creating stone batteries, for giant alloys within the formation of steel, ceramics so on.
