Carbon dioxide is an significant contributor to the enhanced greenhouse effect. It can result in trapping more of the heat that Earth is radiating into space and cause detrimental climate changes and rising sea levels. The main concern regarding the combustion of organic compounds is the result of incomplete combustion. Incomplete combustion occurs when there is not enough oxygen to completely burn the fuel to carbon dioxide and water, causing pollution and fuel inefficiency. For example: Pentane reacts with little oxygen to form
2. What gas is produced naturally in the stratosphere and is also a primary component of photochemical smog in polluted air at the surface? a. carbon dioxide b. carbon monoxide c. ozone d. nitrogen dioxide e. hydrocarbons 3. Which of the following is not considered a temperature scale? a. Fahrenheit b. Kelvin c. Calorie d. Celsius 4.
ceName___________________________________ Homework Chapter 8: Quantities in Chemical Reactions Please answer these questions on a scantron ;-) MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 1) The primary cause of increasing greenhouse gases is: A) the increased use of natural gas, petroleum and coal. B) the release of CO2 by decreasing solubility in the ocean. C) the production of CO2 by respiration.
They changed because the molecules of hydrogen and helium were moving so fast that they eventually escaped the Earth. 14. Explain how the greenhouse effect works and how it relates to global warming. The greenhouse effect is when radiation at visible wavelengths passes freely through the atmosphere and is absorbed at the ground. The ground heats up and emits infrared radiation.
Carbon dioxide does not only cause problems in the atmosphere but also in the ocean. The coming of industrial advancement has brought many changes in the earth’s environment (Gibson et al., 2011). Industrialization has brought an increase in gases released into the atmosphere; carbon dioxide forming the largest percentage. The ocean absorbs about 30% of the carbon dioxide in the atmosphere and, thus the increase of carbon dioxide in the atmosphere leads to a corresponding increase in the amounts the ocean absorbs. When the ocean absorbs carbon dioxide it reacts with water to produce chemicals such as bicarbonates and carbonic acid, which lowers the pH of the ocean.
2. What distinctive characteristics of Earth make it suitable for life? How has life altered the chemistry of Earth’s atmosphere? Water, Energy, Time, Recycling or Plate Tectonics, Magnetic field Protection, and Low Sun Radiation. Life has altered the atmosphere by releasing high levels of carbon dioxide along with other chemicals which has been slowly thinning the atmosphere over the years, 3.
The black shirt would also fade over time because the suns rays would eat up the shirt. #2 Question: Which method of heat transfer describes vertical circulation of a fluid as in Hadley Cell? Correct Answer: C) My Answer: A) Why it’s Wrong: Convection, Because of the circulation in the Hadley cell, two pressure belts are created. The first is a belt of semi permanent high pressure that results from the sinking air at 30°. This belt of high pressure is called the subtropical ridge.
C1.4.3 Hydrocarbon fuels Additional guidance: a) Most fuels, including coal, contain carbon and/or hydrogen and may also contain some sulfur. The gases released into the atmosphere when a fuel burns may include carbon dioxide, water (vapour), carbon monoxide, sulfur dioxide and oxides of nitrogen. Solid particles (particulates) may also be released. Candidates should be able to relate products of combustion to the elements present in compounds in the fuel and to the extent of combustion (whether complete or partial). No details of how the oxides of nitrogen are formed are required, other than the fact that they are formed at high temperatures.
limb_flare_sm.jpg (5710 bytes)Solar flares are tremendous explosions on the surface of the Sun. In a matter of just a few minutes they heat material to many millions of degrees and release as much energy as a billion megatons of TNT. They occur near sunspots, usually along the dividing line (neutral line) between areas of oppositely directed magnetic fields. The biological effect. There is a growing body of evidence that changes in the geomagnetic field affect biological systems.
Sulfuric Acid is a strong acid that exists as a colorless oily corrosive liquid and is made by reacting sulfur trioxide with water. This is most commonly found in batteries, manufacture of fertilizers, explosives, detergents, dyes and other different chemicals. Sulfuric Acid is very dangerous to humans as it can cause respiratory tracts of humans and other animals while doing some major damage to plants that helps provide oxygen for us. Ground-level ozone is a secondary air pollutant formed when sunlight triggers reactions between nitrogen oxides and volatile hydrocarbons. If a human inhales ground-level ozone it can cause chest pain, throat irritation, and congestion.
