Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The substance left over from the reaction
A
Limiting Reactant
B
Excess Reactant
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -An excess reactant is a substance that is not wholly consumed or entirely reacted in a chemical reaction. It is also known as an excess reagent. The amount of product formed is independent of the quantity of excess reactant.

Detailed explanation-2: -The limiting reagent in a chemical reaction is the reactant that will be consumed completely. Once there is no more of that reactant, the reaction cannot proceed. Therefor it limits the reaction from continuing. The excess reagent is the reactant that could keep reacting if the other had not been consumed.

Detailed explanation-3: -8) How much of the excess reagent is left over after the reaction from problem 6 is finished? 21.5 grams of C6H10 will be left over.

Detailed explanation-4: -A substance that does not allow a chemical reaction to take place completely is called the limiting reagent. If a chemical reaction involves a limiting reagent, then the atoms/molecules/ions of the other reactant with which it (limiting reagent ) combines will remain free or will remain unreacted. Eg: C + O-> CO.
