3. Carefully put an egg in a glass half filled with vinegar. Replace the vinegar on the second day. Place the covered glass with the vinegar and egg in a safe place for one week without disturbing it. After one week, pass a light through the egg using a flashlight. N.B. DO NOT BOIL AND EAT THE EGG. A. Results and observation. Equation: HC2H3O2 + CaCO3 calcium acetate + H20 + carbon dioxide B. Calculation: If 9.02 x 1024 particles of vinegar (HC2H3O2)HC2H3O2) is added to 16.5 moles of eggshell (CaCO3) and 6.35 moles g of calcium acetate is formed. What are the (a) theoretical yield, (b) actual yield and (c) percent yield
