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

What is the molarity of a solution made by diluting 0.025L of 6.0 M HCl until
the final volume of the solution is 1.75 L?
Answers
Answer:
Explanation:
Use the dilution equation: M1V1 = M2V2
M1 = 6.0 M
V1 = 0.025 L
M2 = ?
V2 = 1.75 L
(6.0 M)(0.025 L) = M2(1.75 L)
Solve for M2 --> M2 = 0.086 M HCl

How many grams of MgBr2 are needed to create 3.0L of a 4.5M aqueous solution of magnesium bromide?
Answers
Answer:
2486 g
Explanation:
First we calculate how many moles of MgBr₂ are required to create such a solution, using the definition of molarity and the given volume and concentration:
Molarity = moles / liters4.5 M = moles / 3.0 Lmoles = 4.5 M * 3.0 L = 13.5 molNow we convert 13.5 moles of MgBr₂ into grams, using its molar mass:
13.5 mol * 184.113 g/mol = 2486 gWhich particles make up most of the mass of an atom?

What happened during the fusion reaction shown?
Answers
Answer:
the answer to this question B. Two H nuclei that fused into one He necleus
Explanation:
Two hydrogen atoms fused to one helium molecule, hence option B is correct.
What is fusion?Fusion is defined as a process in which two or more atomic nuclei unite to create new atomic and subatomic particles. Heat, which is produced when two atoms fuse, is the key to generating energy. Similar to how nuclear fission produces energy, this heat can be utilized to warm water, produce steam, and turn turbines to produce electricity.
In the core of the Sun, hydrogen is being converted to helium. This phenomenon is known as nuclear fusion. Fusion is what powers both the sun and the stars. One example of this kind of reaction is when two hydrogen atoms combine to form a helium atom. During the process, a portion of the hydrogen's mass is converted into energy.
Thus, two hydrogen atoms fused to one helium molecule, hence option B is correct.

3. How does genetic variation allow humans to survive long-term? Which
type of reproduction is responsible for genetic variation?
Answers
Answer:
more genetic variation within a population usually enables more phenotypic variation.
Explanation:
Because natural selection acts directly only on phenotypes, Some new alleles increase an organism's ability to survive and reproduce, which then ensures the survival of the allele in the population.
Genetic variation lets the organisms survive long term as it increases the phenotypic and the genotypic variation. Genetic variation is due to the type of reproduction that involves two parents.
What is genetic variation?Genetic variation is the modification of the original genome of the organism by genetic recombination and mutation that can be beneficial in the survival and the natural selection process.
Reproduction involving two parents of the same species allow genetic variation as the process of independent assortment and crossing over of the chromosomes inherited from both creates species with different traits and genotype.
Therefore, the reproduction involving two parents results in genetic variation.
