2016年4月18日 · Coal is formed when ancient peat forests are buried and compressed over time. The way coal forms is similar to how other fossil fuels form. Coal is formed when ancient peat forests are buried and compressed over time. Over millions of years, heat and pressure cause the buried organic matter to coal. As the temperature increases, carbon dioxide, oxygen, nitrogen are released, and the proportion ...

2018年1月22日 · Coal is made from organic materials. Coal is classed as an organic sedimentary rock and rocks are made from inorganic (not from living) material such as minerals. Coal is made from decomposed plants that are organic (were living)

2017年10月8日 · Coal, Oil, fast moving rivers, forests, ( maple syrup ) Fishing. The North east does not have the warm climate or rich soils needed for large scale commercial agriculture. However corn, soy beans and even grapes are grown in the Northeast. Coal deposits are extensive. Along with the s, and coal veins are rare earth elements. The first commercial oil fields were in western Pennsylvania. The ...

2017年4月2日 · It is largely due to prevailing winds that guide coal emissions from the Midwest to the North Atlantic and the Northeast. Acid rain is caused by two gases rising into the air in great quantities: sulfur dioxide and nitrous oxide. Those two gases are both produced by coal-firing plants. The Midwest produces a large proportion of the coal that is produced in the U.S. Thus, wind patterns guide ...

2018年1月27日 · There are extra carbon it has to process through Burning of wood, coal, fossil fuels, combustions, etc. All produce carbon dioxide, other reactions produce carbon-related molecules, such as methane. All this carbon has to go somewhere, however, there is simply not enough plants to convert all of them into oxygen. Therefore, the extra carbon is left unprocessed, which is bad for life on Earth ...

2017年11月9日 · The standard enthalpies of formation, ΔH∘fΔHf∘, for C2H2(g), O2(g), CO(g), H2O(g), and CO2(g) are given in the table.

2015年2月17日 · Combustion reaction produce products which have a lower energy state than the reactants which were present before the reaction. A fuel (sugar for example) has a great deal of chemical potential energy. When the sugar burns by reacting with oxygen, it produces mostly water and carbon dioxide. Both water and carbon dioxide are molecules which have less stored energy than what sugar molecules ...

2017年9月25日 · Erosion affects waterways. Erosion affects waterways. If erosion is high, eroded particles deposit in river beds or available banks. Therefore, when there is a flood in such places lots of places will be under water. Erosion also cause river ships unoperability. They are designed to navigate under regular circumstances (canal bed depth and width, for instance). If erosion deposits solid ...

2016年2月27日 · Sulfuric acid (H_2SO_4), nitric acid (HNO_3), and carbonic acid (H_2CO_3) are the major components of acid rain. These chemicals are released into the atmosphere naturally however prior to industrialization and the advent of factories and reliance on hydrocarbons (coal, gasoline, crude oil, et cetera) acid rain was a rare event. In recent decades acid rain has become an increasingly common ...

2018年5月5日 · The alveoli are clusters of small sacs at the end of the bronchiole tubes. These sacs fill with air with each inhalation. The alveoli are surrounded by capillary beds. Both the alveoli and the capillary walls are one cell thick and allows for the diffusion of Oxygen O_2 and Carbon Dioxide CO_2 between the lung tissue and the blood.
