Homework Answers
B should be less than half of A to be a limiting reagent.
In I,
A = 6
B = 6
Hence B > A/2
So not a limiting agent.
In II,
A = 11
B = 5
B < A/2
So B is a limiting agent.
In III,
A = 6
B = 4
Hence B > A/2
So not a limiting agent.
In IV,
A = 6
B = 3
Hence B = A/2
So not a limiting agent.
Hence answer is II

In a chemical reaction, the reactant that limits the amount of product that can be formed...
In a chemical reaction, the reactant that limits the amount of product that can be formed is called the limiting reactant (or limiting reagent). The reaction will stop when all of the limiting reactant is consumed. In the sandwich example, bread was our limiting reactant. The reactant or reactants in a chemical reaction that remain when a reaction stops when the limiting reactant is completely consumed are called the excess reactant(s). The excess reactant(s) remain because there is nothing with...

Write the state of matter for every substance in the chemical reaction. Explain your limiting reactant determinations. Mark every measured number showing the significant figures (SF). Do not round any intermediate values. (you can show two digits past the marked SF) Show subtraction and addition in the vertical format. Show your final answer before rounding and then in the final form, rounded correctly. Every number must have units and substances. You can use tables or other means to increase your...

The limiting reactant is the chemical substance that determines the amount of product(s) that can ultimately be formed in a reaction. During the reaction, the limiting reactant is completely consumed or used up, and therefore, causes the reaction to stop The limiting reactant can be identified through stoichiometric calculations. After comparing the results, the reactant that produces the smaller mass of product is identified as the limiting reactant. Determine the excess reactant and calculate the mass of the remaining excess...
