Assignment Help Chemistry
Reference no: EM132287334

A student performs parts A and B of the experiment and attains an average percent yield from the Alka-Seltzer of 54.4%. Using this value and the following data perform the calculations for part B and complete the table below. Assume the pressure has not changed. You may apply the findings regarding percent-yield in Part A to Part B when calculating the moles of calcium carbonate.

Pressure is 0.9914 atm

Reaction from part A:

  • Alka-Selzter Reaction: 3NaHCO3(aq) +  C6H8O7(aq) →  3CO2(g) +  Na3C6H5O7(aq) +  H2O(l)

Reaction from part A

  • Unknown Antacid Reaction : CaCO3(aq) +  2HCl(aq) →  CO2(g) +  CaCl2(aq) +  H2O(l) 
  • Mass antacid used: 0.3966 grams
  • Volume CO2 Recovered: 0.0181 L
  • Temperature: 287 K

What is:

  • Moles CO2 recovered
  • theoretical coles of CO@
  • Moles CaCO3
  • Grams CaCO3
  • Mass Percent CaCO3
