changing even before carbon dioxide emission by humans. There is no scientific evidence to back claims of man-made global warming period. Anyone who tells you that scientific research shows warming trends – be they teachers‚ newscasters‚ Congressmen‚ Senators‚ Vice Presidents or Presidents – is wrong. In fact‚ scientific research through U.S. government satellite shows that the earth’s atmospheric temperature is actually cooling – very slightly by 0.037 °C. Generally carbon dioxide is considered to be

made activities that largely contribute to global warming and this occurs in automobiles‚ in factories‚ and in electric power plants that provide energy for houses and office buildings” (Global Warming NASA). The burning of fossil fuels produces carbon dioxide ‚ a chemical element that “slows the escape of heat into space” (Global Warming Nasa). “According to the Intergovernmental Panel on Climate Change (IPCC ’s) report‚ CO2

when the earth heats up and the temperature rises. This is caused by green house gases trap heat and light from the sun in the earth’s atmosphere which in turn causes the temperature to increase. Examples of these greenhouse gases are carbon dioxide‚ methane‚ carbon monoxide and nitrous oxide. (library.thinkquest.org‚ 2011). There are two main causes of global warming. The first one being natural causes. Natural causes could include volcano eruptions‚ changes within the earth’s orbit and sunspots

moderately alkaline‚ so it can neutralise strong acids - Can precipitate many metal ions from solution as carbonates Uses of sodium carbonate - Glass manufacturing (most common use) o Used as a flux gas which lowers the melting point of the silicon dioxide and the calcium carbonate - Soap and detergents o Used as a base in soap and detergents. It is also used to make sodium phosphate and sodium silicate that act as builders - Softening hard water o The carbonate ions precipitate calcium and magnesium

cell in your body. Respiration in Cells In your cells‚ oxygen is used to split glucose apart — releasing energy‚ water and carbon dioxide. Photosynthesis Plants take in carbon dioxide and water and use them to make food. Their food is simple sugar — glucose. Photosynthesis (continued) Plants pull the carbon off CO2 and use the carbon in glucose. (They do not need the oxygen for this. They get that from water‚ H2O.) Plants release the oxygen (O2) back into

process converting sugar to gases and occurs in yeast and bacteria. In the experiment we conducted‚ we used sucrose and yeast and measured the fermentation carbon dioxide formation. The factors affecting fermentation that we tested in this experiment were temperature and the effect of a disinfectant. We measured the fermentation carbon dioxide formation by using a ruler and measuring the amount of bubbles in the tube that were formed. To conduct this experiment‚ we used 5 grams of sugar and 2 grams

of these ancient carbon remains‚ it is not a viable option; this is because this requires much effort in the realm of change‚ and changing “the system” would be too costly. Before we can think of a way we can reverse this process and use this excess carbon dioxide to our advantage‚ people must stop it in its tracks. The human race must adopt biofuels‚ mainly because they neither contribute to nor take from the problem. Fuels made from Biomass will only release as much carbon dioxide as they absorb

the average rate of photosynthesis of the leaf discs increased in a linear trend. As it is the sodium bicarbonate which decomposes into carbon dioxide necessary for photosynthesis‚ it is reasonable to consider from Graph 1 that as carbon dioxide concentration of the solution increases‚ the rate of photosynthesis will also increase in a linear trend. Carbon dioxide concentration is shown to be directly proportional to rate of photosynthesis ([CO2] ∝ rate of photosynthesis). The line of best fit in

the rest escapes into space. The more greenhouse gases are in the atmosphere‚ the more heat gets trapped. CAUSES OF GLOBAL WARMING. 1. Global Warming Cause: Carbon dioxide emissions from fossil fuel burning power plants Our ever increasing addiction to electricity from coal burning power plants releases enormous amounts of carbon dioxide into the atmosphere. 40% of U.S. CO2 emissions come from electricity production‚ and burning coal accounts for 93% of emissions from the electric utility industry

belonging to the kingdom fungi. Yeasts live on sugars and produce ethanol and carbon dioxide as by-products. [James Mallory‚ 1984]When Yeasts are given water and sucrose they convert the sucrose into glucose then convert the glucose into carbon dioxide and ethanol following the following reaction: C₆H₁₂O₆ ( 2(C₂H₅OH + CO₂ [Brady Burkhart‚ Terrell Grayson and Eric Kimler‚ 2009] Because yeasts produce ethanol and carbon dioxide they are commonly used in the fermentation of alcoholic beverages and in
