Explain the difference, with sketches, between the titration curves of monoprotic acid and a triprotic acid.
Answers
Answer:
A monoprotic acid has only one equivalence point in a titration curve while a triprotic acid has three equivalence points.
Explanation:
Monoprotic acids, HA, are acids that are able to donate one proton per molecule during the process of ionization or dissociation as shown below:
HA ----> H⁺ + A⁻
A triprotic acid is a polyproprotic acid, that is acids that can donate more than one proton per molecule during ionization. a triprotic acid can donate three protons per molecule during the process of ionization. The dissociation of a triprotic acid is shown below;
H₃A -----> H₂A⁻ + H⁺
H₂A⁻ ----> HA²⁻ + H⁺
HA²⁻ -----> A³⁻ + H⁺
The value Ka, is known as the acid dissociation constant. It is found by looking at the equilibrium constant for the dissociation of the acid. The higher the Ka, the more the acid dissociates
A titration curve is the plot of the pH of the analyte solution versus the volume of the titrant added as the titration progresses.
In a titration curve in which base is added to acid, the pH rises slowly until the equivalent point at which point the pH remains constant before it begins to rise again on the addition of more base.
In a titration curve of a monoprotic acid, there is only one region in which the equivalence point is obtained corresponding to the point of acid of dissociation of all its protons.
In the titration curve of a triproprotic acid, three equivalent points are obtained corresponding to the point of dissociation of each of three protons of the triprotic acid.
The titration curves are shown below

A force of 25 newtons is exerted over an area of 50 square meters. Calculate
the pressure exerted in pascals.
Answers
Answer:
the pressure exerted in pascals is 0.5 Pa
Explanation:
The computation of the pressure exerted in pascals is shown below:
As we know that
Pressure = force ÷ area
= 25 ÷ 50
= 0.5 Pa
Hence, the pressure exerted in pascals is 0.5 Pa
We simply applied the above formula so that the correct pressure could come

3. Use this equation to answer the questions below: Br2 + Cl2 → 2BrCl.
a. How many moles of BrCl form when 2.74 mol Cl2 react with excess Br2?
Answers
Answer:
Explanation:
Br₂(g) + Cl₂(g) => 2BrCl(g)
excess 2.74mole ?moles
Rxn ratio is 1mole Cl₂(g) : 2mole BrCl which means the yield of BrCl must be larger mole value than the Cl₂(g) mole value. This is accomplished by multiplying the given moles Cl₂(g) by a ratio of coefficients that will make the results larger.
moles BrCl(g) produced = 2/1(2.47mole BrCl(g) = 5.48 mole BrCl(g)

Answer:
Explanation:
25 % ( m / v ) mannitol solution means 25 gram in 100 cc of water
25 gram in 100 mL of water
grams of mannitol in 30 mL = 25 x 30 / 100

Initial concentration of [tex]N_2O_4[/tex] = [tex]\frac{1.0mol}{1.00L}=1.0M[/tex]
Equilibrium concentration of [tex]NO_2[/tex] = [tex]\frac{1.0mol}{1.00L}=1.0M[/tex]

Initial conc. 1.0 M 0 M
At eqm. conc. (1.0-x) M (2x) M
The expression for equilibrium constant for this reaction will be,

Given the equation: HCl + Na2SO4 → NaCl + H2SO4, if you start with 8 moles of hydrochloric acid, how many grams of sulfuric acid will be produced?
Answers
Answer:
392g sulfuric acid are produced
Explanation:
Based on the balanced equation:
2HCl + Na2SO4 → 2NaCl + H2SO4
2 moles of HCl produce 1 mole of sulfuric acid
To solve the problem we need to find the moles of sulfuric acid produced based on the chemical equation. Then, using its molar mass -Molar mass H2SO4 = 98g/mol- we can find the mass of sulfuric acid produced:
Moles sulfuric acid:
8mol HCl * (1mol H2SO4 / 2mol HCl) = 4 mol H2SO4
Mass sulfuric acid:
4mol H2SO4 * (98g / mol) =
392g sulfuric acid are produced

Explanation:
The charge of the Fe ion in the compound [tex]\rm FeO[/tex]is +2 and the charge of the Fe ions in the compound [tex]\rm Fe_2O_3[/tex] is +3, respectively.
Ion can defined as any atom or molecule having positive or negative charge on it.
In [tex]\rm FeO[/tex]: In the compound, oxygen is in group 16 and has a charge of -2, the iron ion must have a charge of +2 to balance the charges and make the compound neutral.
In [tex]\rm Fe_2O_3[/tex]: In the compound, oxygen is in group 16 and has a charge of -2, the three oxygen atoms in [tex]\rm Fe_2O_3[/tex] contribute to a total charge of -6. To make the compound neutral, the two iron ions must have a total charge of +6. Therefore, each iron ion must have a charge of +3 to balance the charges and make the compound neutral.
Therefore, Fe ion has a charge of +2 in the compound [tex]\rm FeO[/tex] and has a charge of +3 in the compound [tex]\rm Fe_2O_3[/tex].
