    inaccurate timing as the reflect time to stop the stopwatch when 30cm3 of carbon dioxide is collected in 100mL measuring cylinder is often various from time to time. Time may be longer or shorter than the actual time taken to collect 30cm3 of carbon dioxide. This will then lead to the wrongly calculation of the rate of reaction as the formula of the rate of reaction is: Rate of reaction=1/(Time taken to collect 30.0cm³ of carbon dioxide (s)) Next, the sources of the random errors in this experiment are

    Research Question: To investigate and compare how different temperature (5℃, 15℃, 25℃, 35℃, 45℃) can affect the concentration of carbon dioxide in soda water through titration with sodium hydroxide solution. Introduction: Carbon dioxide plays an important role in soft drinks. Soda water is manufactured by pumping carbon dioxide into water under high pressure. Carbon dioxide dissolves in water to form carbonic acid, which is the fizz we find in soft drinks. CO2 + H2O ⇌ H2CO3 The popping sound we

    which is essential for life. We exhale carbon dioxide that can be tested for limewater because carbon dioxide dissolves in water to form carbonic acid (H2 C03). Glucose is a reactant of respiration. The glucose in your blood comes from carbohydrates in your food. Carbohydrates include sugar and starchy foods like: bread, pasta and rice. Keywords: Carbon dioxide, Glucose, Water, Oxygen and energy. Word and Symbol equations: Glucose + oxygen = Carbon dioxide + water C2H12O6 + 602 = 6CO2 + energy

    enables organisms to harvest stored in them in a form of ATP. The glycolytic pathway produces a net yield of two ATPs. Yeast undergo fermentation and produce ethanol and carbon dioxide. Carbon dioxide can be used to measure the rate of fermentation. In this study the rate of fermentation was measured through the production of carbon dioxide into a test collection tube over a 25 minute period. Fermentation increases steadily

    “Photosynthesis is the most important reaction on Earth. “ –unknown (Brainy quotes). photosynthesis is a chemical process in which plants and other organisms use sunlight to synthesise nutrients from water and carbon dioxide. (source 1) Photosynthesis includes a significant scientific background behind it. The process takes place in chloroplasts, which is a type of plant cell organelle frequently referred to a plastid. They are recognised to be eukaryotic cell structures. The chloroplast a green

    Extinction by Elizabeth Kolbert, is solely devoted to her experience in these waters where the vents on the sea floor bubbled up almost 100% carbon dioxide. She talks about the consequences of constantly burning fossil fuels to add about 365 billion metric tons of carbon into the atmosphere and how it could lead to our own demise. The thing about carbon dioxide is that the moment it interacts with water, it becomes an acid which can be deadly to the animals living in these oceans obviously, but also

    Stomata are pores commonly found on the underside of leaves of a plant (stomata study). These microscopic pores are a passageway for carbon dioxide to enter while at the same time allow water and oxygen to be released (berkley). Plants need stomata as they allow the plant to take in carbon dioxide, a necessary part of photosynthesis (berkley). Plants open stomata by their guard cells located on either side of the stomata (stomata study). These cells can swell up to open the stomata or deflate to

    Elodea Canadensis is an aquatic weed that, like any other plant, uptakes carbon dioxide during photosynthesis and produces it through aerobic respiration. The purpose of this experiment was to measure the amount of carbon dioxide production in Elodea Canadensis plant with varying light source distances in order to understand whether more photosynthesis than aerobic respiration in the plant has occurred. This was done through a two-day experiment where the Elodea plant was first placed under a light

    which are glucose and oxygen, while photosynthesis uses the products in aerobic cellular, which are carbon dioxide and water. These reactions are how cells make and store energy. Photosynthesis occurs in the chloroplast, while cellular respiration occurs in the mitochondria. Although these processes differ, they do have several similarities. Aerobic cellular respiration

    absorption of carbon dioxide, also known as CO2, by the ocean. This causes the acidity of oceans to rise and the PH levels to fall. Humans are directly contributing to the problem in many ways. One of the ways is the amount of fossil fuel society emits. Another way people are contributing is by deforestation. Because people don’t feel or see the increase the increase of CO2, they do not believe that it is negatively affecting the marine life. The ocean absorbs roughly thirty percent of the carbon dioxide

    Do humans cause global warming or is it natural? Many researchers, scientists, and environmentalists are expressing concerns about changes in the overall climate of the `earth. Some believe that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as "global warming”. What is global warming? Global warming is an increase in the average temperature at Earth's surface (“global warming”). Global warming is all about adverse climate change caused

    seeds/plants are autotrophic organisms, which produce their food from the energy that the light provides them. To release the stored energy within the food molecules, the germinated seeds carry out respiration and the release of carbon dioxide. Oxygen was being consumed and carbon dioxide was being released because the water level in test tube “G” continued to

    within each chloroplast in most of the green plants, and Carbon dioxide is one of the main components of this process. Plants use photosynthesis to produce their own food (glucose), some water and the oxygen that we need. The overall balanced equation is: 12 H2O+ 6 CO2 → 6 H2O+ C6H12O6 + 6 O2 Sunlight energy Where: CO2 = carbon dioxide H2O = water Light energy is required C6H12O6 = glucose O2

    immediately reducing global warming, a shift away from methane-emitting food sources is much easier than cutting carbon dioxide. First, there is no limit to reductions in this source of greenhouse gas that can be achieved through vegetarian diet. Second, shifts in diet lower greenhouse gas emissions much more quickly than shifts away from the fossil fuel burning technologies that emit carbon dioxide. The turnover rate for most ruminant farm animals is one or two years, so that decreases in meat consumption

    The relationship between Photosynthesis and Cellular Respiration is that the reactants on photosynthesis are the products to cellular respiration, and the products of photosynthesis are the reactant. Photosynthesis removes carbon dioxide from the atmosphere while cellular respiration puts it back into the atmosphere. Photosynthesis releases oxygen into the atmosphere, and cellular respiration uses that oxygen to release energy from food. Cellular respiration and photosynthesis differ because they

    dreaming, this could actually happen if the glaciers and the ice capes continue to melt at the speed they are now do to global warming. The main cause of global warming is the Greenhouse effect. This effect is natural and holds certain gases like carbon dioxide and methane and helps the Earth stay warm. The Industrial Revolution was not natural and directly contributed to the Greenhouse effect. According to Michaels and Balling, authors of Climate of

    change is increasingly recognized as a major challenge. It is widely accepted that the greenhouse gas emissions caused by humans are having a negative impact on the environment. The most important greenhouse gas, arising from human activity, is carbon dioxide (CO2). Virtually all human activities cause the CO2 emissions that lead to climate change. By using electricity generated from fossil fuel power stations, burning gas for heating or driving a petrol or diesel car, every person is responsible for
