How does a limiting reagent affect how much product is formed?
O A. The amount of product will be limited by the molar mass of the
limiting reagent
B. The amount of product will be limited by the sum of the reactant
coefficients.
C. The amount of product will be limited by the number of moles of
the limiting reagent.
D. The amount of product will be limited by leftover amounts of other
reactants.
Answer:
C. The amount of product will be limited by the number of moles of
the limiting reagent.
Explanation:
a p e x :)) i just took the quiz
The amount of product will be limited by the number of moles of
the limiting reagent. Hence, option C is correct.
What is a Limiting reagent?The reactant that gets consumed early in the reaction restricts the quantity of product which will be produced in the chemical reaction. Thus, the reactant that gets consumed early in a chemical reaction is a limiting reagent.
Hence, the amount of product will be limited by the number of moles of the limiting reagent.

Las capas del lecho marino del Mar Mediterráneo cuentan la historia de los cambios ambientales en el hoy desértico norte de Africa desde hace 160.000 años, haciendo uso de la regla de tres simple y notación científica indicar a cuántas décadas corresponde este periodo de tiempo con procedimiento
Answer:
160.000 años corresponde a 16.000 décadas.
Explanation:
Para resolver correctamente el ejercicio debemos plantear la regla de tres simple de la siguiente manera:
1 década equivale a 10 años; A cuantas decadas equivalen 160.000 años?
1 década→10 años
x ←160.000 años
Debemos multiplicar 160.000 por 1 y luego dividir entre 10 ;
x=([tex]\frac{160.000x1}{10}[/tex])=16.000 décadas; en notación científica sería 16x10^3.
Respuesta: 160.000 años corresponde a 16.000 décadas.
What is the molarity when 1.25 mol is dissolved in 3.50 L of solution?
Answer:
0.36 mol/L
Explanation:
The formula for molarity M=m/L
m stands for moles
L stands for liters
Plug it into the equation...
M=1.25 mol/3.5 L
M=0.35714285714

A chemist prepares a solution of silver(I) perchlorate by measuring out of silver(I) perchlorate into a volumetric flask and filling the flask to the mark with water. Calculate the concentration in of the chemist's silver(I) perchlorate solution. Be sure your answer has the correct number of significant digits.
The question is incomplete, the complete question is;
A chemist prepares a solution of silver (I) perchlorate (AgCIO4) by measuring out 134.g of silver (I) perchlorate into a 50.ml volumetric flask and filling the flask to the mark with water. calculate the concentration in mol/L of the silver (I) perchlorate solution. Round your answer to 2 significant digits.
Answer:
13 mol/L
Explanation:
We must first obtain the number of moles of silver I perchlorate involved
Molar mass of silver I perchlorate = 207.32 g/mol
Number of moles of silver I perchlorate = 134g/207.32 g/mol = 0.646 moles
Recall that;
n =CV
C= concentration
V= volume
n = number of moles
C = n/V
C = 0.646 moles * 1000/50
C = 13 mol/L
2. Explain in your own words what will happen to the chemical structure of aspirin when it is in solution at pH 1.0. Compare this to what will happen to the chemical structure of aspirin at pH 8.0. Highlight your answers by drawing appropriate chemical structures for aspirin at each of the pH values.
Answer:
don't sent such messages whatever you are
According to the concept of solubility and dissociation, aspirin at pH 8 and 10 undergoes dissociation to yield ions.
What are ions?
An ion is defined as an atom or a molecule which has a net electrical charge. There are 2 types of ions :1) cation 2) anion . The cation is the positively charged ion and anion is the negatively charged ion . As they are oppositely charged they attract each resulting in the formation of ionic bond.
Ions consisting of single atom are mono-atomic ions while which consists of two or more ions are called as poly-atomic ions . They are created by chemical interactions . They are very reactive in their gaseous state and rapidly react with oppositely charged ions resulting in neutral molecules.Ions are generated on dissociation.

In this case you have unlimited iron, but only 6.40 moles of oxygen (O2). How much Fe2O3 can you produce?
Answer: 682 grams
Explanation:
The balanced chemical reaction is:
[tex]4Fe+3O_2\rightarrow 2Fe_2O_3[/tex]
[tex]O_2[/tex] is the limiting reagent as it limits the formation of product and [tex]Fe[/tex] is the excess reagent.
According to stoichiometry :
3 moles of [tex]O_2[/tex] produce = 2 moles of [tex]Fe_2O_3[/tex]
Thus 6.40 moles of [tex]O_2[/tex] will produce=[tex]\frac{2}{3}\times 6.40=4.27moles[/tex] of [tex]Fe_2O_3[/tex]
Mass of [tex]Fe_2O_3=moles\times {\text {Molar mass}}=4.27moles\times 159.69g/mol=682g[/tex]
Thus 682 g of [tex]Fe_2O_3[/tex] will be produced from 6.40 moles of oxygen
