Dala Shoot! Chemical Reactions 2. in a clean, dry test tube, place a small amount of calcium carbonate. Carefully and slowly add about 3 mL of 6 M HCl solution. Remember that carbonic acid is NOT a gas, but an aqueous acid that decomposes into carbon dioxide and water. Allow the reaction to proceed for 60 seconds, the insert a lit splint into the test tube. What did you observe? From your observation, determine what gas is evolved. TABLE 9.17...

Part IV. Decomposition Into a test tube, place about 2 mL of 3% hydrogen peroxide along with a pea size amount of Mnog Manganese dioxide, the common name, is used as a catalyst. Remember, that a catalyst is used to lower the activation energy of a reaction, thereby speeding up the reaction. It does not get con- sumed in the reaction and therefore is not part of your balanced chemical equation. It is written above the reaction arrow in a...

Chemical Reactions & Equations System 1: Reaction of Sodium Metal with Water Observations: solution start to produce vapor and eventually catches fire Reaction Type: Balanced Equation: (Na with H2O) Reaction in words: The hydrogen gas produced in the reaction can ignite in the presence of oxygen gas in the air. If you observed flames above, it was likely due to this reaction Reaction Type: Balanced Equation: (hydrogen gas with oxygen gas): System 2: Combustion Reactions of Methane (CH4) and Cellulose...
