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 of the Alka-Seltzer reaction. Possible factors to be investigated include

Gas Laws Lab Introduction: The four basic physical properties of a gas sample are pressure‚ volume‚ temperature‚ and number of moles. The volume simply indicates the volume of the container since a gas will take up all space available to it. The temperature indicates the average kinetic energy of the gas particles. For gases‚ the temperature must be converted to the Kelvin unit. The pressure of the gas indicates the number of collisions with each other and the wall of the container. The number

The purpose of this lab was to use gas chromatography to determine the relative amounts of the three components of gas products from the dehydration reaction of 1- and 2-Butanol with sulfuric acid and the dehydrobromination reaction of 1- and 2-Bromobutane with potassium tert-butoxide. E1 reactions are two-step unimolecular reactions. The first step of an E1 reaction occurs when a leaving group‚ which consists of a weak base‚ leaves an organic compound‚ leaving an intermediate carbocation. In the

Greenhouse gas emission What is greenhouse gas? A greenhouse gas is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. Many greenhouse gases occur naturally‚ such as water vapor‚ carbon dioxide‚ methane‚ nitrous oxide‚ and ozone. Others such ashydrofluorocarbons (HFCs)‚perfluorocarbons (PFCs)‚ andsulfur hexafluoride (SF6) result only from human industrial processes. Greenhouse gases act like a blanket around Earth‚ trapping energy in the atmosphere and causing
