Question 6 1 pts Mark all of the statements that are TRUE for the limiting reactant in any chemical process. You must know the balanced equation for the reaction to determine the limiting reactant The limiting reactant limits the amount of product(s) formed. The limiting reactant is present in the smallest mass. The limiting reactant leads to the formation of the smallest amount of product. The limiting reactant is completely consumed during a chemical reaction. Question 7 1 pts Take...
Question text A limiting reagent is Choose...consumed completelyleft over in excess during a chemical reaction, and it Choose...decreasesincreases the possible amount of product that can be formed. Question 2 Not yet answered Points out of 1 Flag question Question text A student used 7.15 g of CaCl2 and 9.25 g of K2CO3 to make CaCO3. The reaction is: K2CO3(aq) + CaCl2(aq) = CaCO3(s) + 2KCl(aq). Based on the masses of the two reactants given, the limiting reagent is Choose...CaCl2K2CO3 ....

what is my limiting reagent, theoretical yield
calculated from moles , and % yield for the synthesis of banana
oil?
Isoamyl acetate (banana oil) is made by the acid
catalyzed reaction (fischer esterification) between isoamyl alcohol
and acetic acid. sulfuric acid was used as the catalyst for the
fast conversion of product from starting alcohol and acid. the
catalyst only affects the rate of the reaction not the extent of
the reaction.
here is the data from lab:
