analysis due to the exclusion of the previous one) was successful, and measurements can be seen below. We then moved onto the second reaction using magnesium oxide and hydrochloric acid in the fume hood. We measured 200.1 mL of HCl and placed it in the calorimeter, and initial temperature reading was taken. Next, we measured 1.07 g of magnesium oxide, using a balance in the fume hood, added it to the HCl in the calorimeter, and shut the lid quickly to conserve heat. This mixture was “swirled”…

The comparison of emissions between the electric and gas cars has played a key role in determining which type is more environmentally-safe. Vehicle exhaust has brought many discussions because of its contribution to climate change. Due to electric vehicles splitting their power between electricity and gas, they emit fewer greenhouse gases and have a smaller carbon footprint (Duivenvoorden, 2014). Gasoline cars account for much of the dangerous exhaust gases entering the atmosphere. However,…

Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide which can be released in different ways. Both Sulfur dioxide (SO2) and nitrogen oxide (NO) are primarily released by human sources such as electricity generation, factory emissions and motor vehicles. Energy generation through the process of burning coal is a primary contributor to gaseous…

of how destructive this power source is. Coal power produces a number of problems that directly and indirectly effect human health, environment, and global warming. Coal contains Sulfur, and when it is burned for energy it produces Sulfur oxide. Nitrogen oxide is also emitted into the…

These nonroad vehicles produce a large amount of air pollution which with this rule will drastically decrease the emissions over time. Nonroad diesel engines contribute a large amount of emissions which include particulate matter (PM) and nitrogen oxides (NoX). Both contribute to heath problems and air pollution, and with this rule it will help decrease the amount of emission on nonroad diesel engines. Engine manufactures will have to produce an engine…

If heating magnesium in the presence of oxygen and they react completely, then the ionic compound’s empirical formula can be found using this equation by calculating the masses of magnesium and oxygen in this equation: Mg + O2 → MgxOy Since an ionic compound is the hopeful result of this lab, an ionic compound is a chemical compound comprising ions, which ions are an atom or molecule with a net electric charge due to the loss or gain of an electron. Ions can be negatively charged and called…

In 1959, metal–oxide–semiconductor field-effect transistor (MOSFET) was invented by Dawon Kahng and Martin M. (John) Atalla at Bell Labs. Julius Edgar Lilienfeld had already patented the basic principle of this kind of transistor in 1925. But later the Bell Labs edition was allocated the name bipolar junction transistor, or merely junction transistor, and design of Lilienfeld came to be identified as field effect transistor. Later, Jean Hoerni found that Silicon dioxide (SiO2) should be used to…

times more heat that carbon dioxide and methane remains in the atmosphere for about ten years. Dinitrogen oxide is commonly called nitrous oxide, most people recognize this as “laughing gas”. The major sources are from the extensive use of fertilizers, sewage treatment plants, and car exhaust. Dinitrogen oxide in the atmosphere has increased about 15% since industrialization. Dinitrogen oxide released in the atmosphere today will remain there for 150 to 180 years and has a greenhouse effect that…

their hands on the commonly known as laughing gas (Nitrous oxide (NO2)). It is the same substance that sometimes dentists used to knock patients out for teeth operations. NO2 causes a high that can last from a few seconds to a few minutes, but it can be very dangerous if taken in large doses. Even the famous did not escape from this trend; actress Demi Moore was said to be abusing whip-its (the whipped cream chargers filled with nitrous oxide) before she was hospitalized in 2012 (Drugabuse.com,…

gaseous pollutants in the air such as oxides of carbon, sulphur. Refuse burning: Refuse disposal is a major environmental problem that has contributed immensely to high level of air pollution in my community. The refuse is usually from multiple sources including domestic, and agricultural sources. One of the environmentally unfriendly methods of managing the waste is by open burning. Often times the air within refuse burning sites is contaminated with oxides of, carbon, nitrogen, and sulphur…
