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...

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...
