Dancing Spaghetti Lab Materials Spaghetti Raisins Beaker Water Baking soda atomic take 11 hydrogen cokeate acetum Procedures 1. Gather the lab supplies from the locker for the designate group number. 2. Fill the 600mL beaker ¾ broad with urine. 3. Mass 10g of atomic number 11 hydrogen carbonate NaHCO3 ( pay back a folded up piece of paper to the face up and venture the come up using the scupula, then mass it on the sense of equilibrium for an holy measurement). 4. Measure out 45mL of acetic venomous CH3carbonic acid gasH (pour an estimated amount in a 250 ml beaker then bring it to your beam and pour it into the 50mL graduated cylinder to get under ones skin an accurate measurement). 5. confine a sort by adding the sodium bicarbonate (NaHCO3) to the weewee (H2O). 6. Make a firmness by rousing the mixture very well with the scupula, most of the sodium bicarbonate should be dissolved. 7. Pour 45mL of acetic acid (CH3CO2H) to the s odium bicarbonate ascendent (NaHCO3). 8. Put ten 2cm pieces of vermicelli in the solution. 9. Put 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 float up to the top and back to the tail end repeatedly.

The more vinegar you added the faster they would go up until they reached an equillibrium and colonize down at the bottom of the beaker. Conclusion Vinegar ( HC2H3O2 ) is a solution of acetic acid. It reacts with baking soda, sodium bicarbonate (NaHCO3 ), to pretend carbon dioxide gas (CO2) and an aqueou s solution of sodium ethanoate (NaC2H3O2). T! he answer can be written as follows. NaHCO3 (aq) + HC2H3O2 (aq) ------> CO2 (g) + H2O (l) + NaC2H3O2 (aq) Bubbles of carbon dioxide gas attach to the pop out of the spaghetti. The moment is that the slow-wittedness of the spaghetti and the gas is less than that of the water solution so the pieces line up to the surface. Many of the bubbles pop at the surface and the density is erstwhile again greater than that of...If you want to get a full essay, order it on our website: OrderCustomPaper.com
