Carbon Dioxide from Cars U.S. states are beginning to attack another major source of global warming pollution besides power plants: your car. David Biello reports Cars in California offer a new kind of sticker shock this year: carbon. In addition to the familiar smog ratings, labels on new Cali cars rank them 1 to 10 based on greenhouse gas emissions. The best, a perfect 10, will emit less than 200 grams of greenhouse gases per mile. The bad ones more than 520. Vermont will also begin offering...

Carbon Dioxide Understanding and Production in Elodea, Snail, and Goldfish Introduction This report discusses an experiment to study the rate of aerobic cellular respiration in aquatic organisms which are Elodea (aquatic plant), Snail, and Goldfish, by measuring carbon dioxide production. Because ectothermic organisms (Elodea, snail, and goldfish) were placed in completely covered beaker, each organism would produce different amount of carbon dioxide. The objective of the experiment is to measure...

Carbon Dioxide and Deforestation

deforestation is responsible for approximately 20% of world greenhouse gas emissions. Recent calculations suggest that carbon dioxide emissions from deforestation and forest degradation (excluding peatland emissions) contribute about 12% of total anthropogenic carbon dioxide emissions with a range from 6 to 17%.Deforestation causes carbon dioxide to linger in the atmosphere. As carbon dioxide accrues, it produces a layer in the atmosphere that traps radiation from the sun. The radiation converts to heat...

Each tablet contains aspirin (acetylsalicylic acid), citric acid, and sodium bicarbonate. As the tablet dissolves in water, the bicarbonate ions in the tablet react with the hydrogen ions from the acids that are also contained in the tablet. The carbon dioxide gas produced by the reaction is what causes the bubbling that can be observed. HCO3- (aq) + H+ (aq) → H2O (l) + CO2 (g) In this investigation, you will design two experiments which will compare two different factors that may affect the rate...

3. Carbon dioxide Their presence is important for the buffering capacity of the water. The level of carbon dioxide in the water is related to photosynthetic activity of aquatic plants and respiration of these plants and aquatic animals, as well as bio-oxidation of organic compounds. Dissolved carbon dioxide forms carbonic acid, causing a drop in pH. At equilibrium, freshwater contains about 2.0 mg/L CO2 and seldom rises above 20 to 30 mg/L.

unethically. At the centre of the government’s policy on climate change is pricing carbon. Many commenters and politicians have referred to this as a “carbon tax”. The idea is that polluters will pay per tonne of carbon they release into the atmosphere. This cost will initially be set at $23, and increase gradually until 2015. This is widely thought of as the most effective and least costly mechanism to reduce carbon output and reduce the level of climate change that is occurring. ...
