Question

please help me with balanced chemical equation and percent yield above is my trial.

Data and Calculations, Part 2: 28. 27 used or + 26.18 Data for Trial #1: 1. 1987 16 empty flask: 19A Mass of flask plus baking soda: Mass of baking soda (calculated): _1.49 11 49.5/ 1.49 Mass of graduated cylinder with 50mL of vinegar: Mass of graduated cylinder after vinegar is poured out: Mass of vinegar transferred (calculated): 69.89 & sloos 20.38 49.51 e 77.11 50.33 (X) 51.00 M 0.67 B (Y-X) Mass of the flask with solution (after reaction is complete): Mass of the solution (calculated): Combined mass of vinegar plus baking soda (calculated): Mass of carbon dioxide gas produced during reaction (calculated): Percent Yield of Carbon Dioxide Gas: Percent yield compares how much product we actually obtain (actual yield) to the amount of product we were supposed to obtain (theoretical yield). The formula to calculate percent yield is: actual yield Percent yield theoretical yield oretical yield (100) Percent Yield Calculations: Determine your percent yield of carbon dioxide for each of your two successful trials. Show each step of your work. To accomplish this you must first start with the balanced chemical equation. Then calculate the theoretical yield, in which you will determine how much carbon dioxide should be produced from the amount of baking soda you started with.

Answer 1

ICH COOH + NaHCO CH₃COONa + HO + Co. Acetic acid soduim bicarbonate. (Vineger) (Baking soda) Molar mass of NaHCO₃ = 84.007g mel foom Molar mass of coa 44.0l almal... - From reactions 84.007g Natco gives 44.01g CO2 - 1.49g NaHCO will give 44.0 x 1.49 g co 84.007 = 0.78 g co₂ Percent yield = actual yield x 100 theoretical yield 0.679 x 100 0.789 = 85.9 %
