Dancing Spaghetti Lab Materials Spaghetti Raisins Beaker Water Baking soda sodium hydrogen cokeate acetum Procedures 1. Gather the lab supplies from the locker for the charge group upshot. 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 think the measuring rod using the scupula, then mass it on the commensurateness for an holy measurement). 4. Measure out 45mL of acetic venomous CH3 carbon dioxideH (pour an estimated amount in a 250 ml beaker then bring it to your transport and pour it into the 50mL graduated cylinder to stool an accurate measurement). 5. deliver a premix by adding the sodium bicarbonate (NaHCO3) to the pee (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 sodium bicarbonate ances tor (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 bay window repeatedly.

The more vinegar you added the faster they would go up until they reached an equillibrium and colonised 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 start out carbon dioxide gas (CO2) and an aqueous solution of sodium ethanoate (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 place of the spaghetti. The contribute 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: OrderEssay.net
