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

to the overall improvement of the environment. Forests have many important and varied functions‚ and to have a broad idea some of them are listed below: Forests are the renewable resources of nature. They are giant sinks of carbon: they absorb and assimilate carbon dioxide‚ which accounts for the majority of the greenhouse gases that are now accelerating global warming. They are home to living creatures‚ They contribute in maintaining biodiversity They regulate the climate They provide industrial

on the effects of cutting and replanting‚ such as Carbon Dioxide‚ and Global Warming. Following this will be methods for planning a forest‚ and how they are conveyed before planting in a forest begins. There are many reasons why forests are cut down. One is to benefit economically‚ with furniture and home building. But there is also another reason. Arguments say "the United States could help slow the atmospheric accumulation of carbon dioxide by replacing old-growth forests with faster-growing

2: Aerobic Respiration in Beans We will evaluate respiration in beans by comparing carbon dioxide production between germinated and nongerminated beans. As shown in the balanced equation for cellular respiration‚ one of the byproducts is CO2 (carbon dioxide): C6H12O6 + 6 H2O + 6 O2 → energy + 6 CO2 + 12 H2O We will use a carbon dioxide indicator ( bromothymol blue) to show oxygen is being consumed and carbon dioxide is being released by the beans. Bromothymol blue is an indicator that turns yellow
