Dancing Spaghetti Lab Materials Spaghetti Raisins Beaker Water Baking soda atomic number 11 hydrogen cokeate vinegar Procedures 1. Gather the lab supplies from the locker for the assigned grouping number. 2. Fill the 600mL beaker ¾ broad with urine. 3. stack 10g of atomic number 11 hydrogen carbonate NaHCO3 ( acquit indorse a folded up piece of paper to the plaque up and estimate the follow using the scupula, and so large number it on the balance for an hallowed measurement). 4. Measure out 45mL of acetic venomous CH3carbonic acid gunmanH (pelt an estimated amount in a 250 ml beaker then bring it to your station and pour it into the 50mL graduated cylinder to croak an accurate measurement). 5. profit a mixture by adding the sodium bicarbonate (NaHCO3) to the water (H2O). 6. Make a firmness by rousing the mixture precise well with the scupula, most of the sodium bicarbonate should be dissolved. 7. stream 45mL of acetic acid (CH3CO2H) to the sodium bicarbonate solution (NaHCO3). 8. pitch ten 2cm pieces of vermicelli in the solution. 9. dictate 5 raisins in the solution. Data In this experiment we observed that when the teacher added vinegar to the solution the raisins and spaghetti started to wander up to the top and back to the potty repeatedly.

The more vinegar you added the faster they would go up until they reached an equillibrium and colonized down at the bottom of the beaker. Conclusion Vinegar ( HC2H3O2 ) is a solution of acetic acid. It reacts with baking hot soda, sodium bicarbonate (NaHCO3 ), to invoke carbon dioxide gas (CO2) and an aqueous solution of sodium acetate rayon (NaC2H3O2). The answer can be written as follows. NaHCO3 (aq) + HC2H3O2 (aq) ------> CO2 (g) + H2O (l) + NaC2H3O2 (aq) Bubbles of carbon dioxide gas attach to the grow of the spaghetti. The issuing is that the slow-wittedness of the spaghetti and the gas is slight than that of the water solution so the pieces line up to the surface. many an(prenominal) of the bubbles pop at the surface and the density is erstwhile again greater than that of...If you want to crush a full essay, differentiate it on our website: Ordercustompaper.com
