What is used up in and stops a chemical reaction?
Answers
Answer:
This question is incomplete but the completed question is below
What is used up in and stops a chemical reaction? (a) percent yield (b) limiting reactant (c) theoretical yield (d) excess reactant
The correct option is (b)
Explanation:
A chemical reaction is a chemical combination,rearrangement or disintegration of chemical substance(s) (called reactants) to form new chemical substance(s) (called products).
A limiting reactant is the reactant that is totally used up during the course of a reaction. When this reactant is used up, it limits the amount of products formed and eventually stops the chemical reaction.
Hi
The chemical reaction does not stop until the reagent is used .
I hope that's help !

Further Explanation:
Rutherford’s experiment:
Rutherford's model of atom is the classic model of the atom instead of having many limitations. He designed an experiment that used alpha particles emitted by radioactive elements as objects that can demonstrate the structure of the atom. Rutherford showed his own physical model for the subatomic structure as a result of the experimental observations.
The postulates of Rutherford’s model are as follows:
1. An atom consists of a positive charge in a very small volume. Most of its mass is concentrated in a very small region of the atom and this region was termed as the nucleus of the atom.
2. The nucleus of the atom is surrounded by the negatively charged particles which were called electron. These electrons were supposed to revolve around the atomic nucleus in a circular path at a very high speed. This circular path is called orbit.
3. A very strong electrostatic force of attraction holds together the negatively charged electrons revolving around the nucleus positively charged concentrated in the nucleus.
Limitations of Rutherford’s model:
1. It did not tell anything about the distribution of electrons in various orbits.
2. This model failed to explain Maxwell’s theory of electromagnetic radiation.
3. It was unable to explain the stability of an atom.
Therefore most of the volume of an atom is taken up by empty space in the atom.

Taking into account the definition of dilution, the molarity of the diluted solution is 0.125 M.
Dilution
When it is desired to prepare a less concentrated solution from a more concentrated one, it is called dilution.
Dilution is the process of reducing the concentration of solute in solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.
In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.
A dilution is mathematically expressed as:
Ci×Vi = Cf×Vf
where
- Ci: initial concentration
- Vi: initial volume
- Cf: final concentration
- Vf: final volume
Final molarity
In this case, you know:
- Ci= 0.15 M
- Vi= 125 mL
- Cf= ?
- Vf= 125 mL + 25 mL= 150 mL
Replacing in the definition of dilution:
0.15 M× 125 mL= Cf× 150 mL
Solving:
(0.15 M× 125 mL)÷ 150 mL= Cf
0.125 M= Cf
In summary, the molarity of the diluted solution is 0.125 M.

Answer:
0.125 M
Explanation:
M₁V₁ = M₂V₂
125 mL / 1000 = 0.125 L = V₁
25 + 125 = 150 mL / 1000 = 0.150 L = V₂
0.15 M = M₁
M₁ × V₁ / V₂ = M₂
(0.15) × (0.125) / (0.150) = 0.125 M
0.125 M is the answer
