Answer 1

2.48 0.709

i got it right on edg so enjoy

Answer 2

Ans: 0.709 moles glycerin

The given reaction is:

14KMnO4 + 4C3H5(OH)3 → 7K2CO3 + 7Mn2O3 + 5CO2 + 16H2O

a) Based on the reaction stoichiometry:

5 moles of CO2 requires 14 moles of KMnO4

Therefore, 0.886 moles of CO2 would correspond to:

= 0.886 moles CO2 * 14 moles KMnO4/5 moles CO2

= 2.48 moles

b) Again from the reaction stoichiometry:

5 moles of CO2 requires 4 moles of glycerin

therefore, 0.886 moles of CO2 would consume:

= 0.886 moles CO2 * 4 moles glycerin/5 moles CO2

= 0.709 moles
