Answer:

B. 8.8 x 10⁻¹²

Explanation:

In aqueous solution, silver chromate (Ag₂CrO₄) dissociates into ions as follows:

Ag₂CrO₄(s) ⇄ 2 Ag⁺(aq) + CrO₄²⁻(aq)

                       2s               s

So, the expression of the Ksp of Ag₂CrO₄ is derived from the concentrations of the ions at equilibrium raised by the stoichiometric coefficients:

Ksp = [Ag⁺]²[CrO₄²⁻] = (2s²)s = (4s²)s = 4s³

Since s = [Ag⁺] = 1.3 x 10⁻⁴ M, we calculate the Ksp as follows:

Ksp = 4s³= 4(1.3 x 10⁻⁴)³ = 8.79 x 10⁻¹² M

Therefore, the correct option is B. 8.8 x 10⁻¹²

Name and Title:  

Mitosis and Meiosis Lab Report.  

Objective(s):  

To learn and explore what mitosis and meiosis is and what they do.  

Hypothesis:

Record your predictions during the zoo tour section of the lab in the data chart.

Procedure:

First, go into the mitosis and meiosis cycles. Then look at what happens when a sex cell from a female tiger is combined with a sex cell from a male tiger. Then investigate what happens when two starfish reproduce asexually. Then write down the predictions about how each organism will replicate. Then, keep track on whether or not the forecast was right.

Data:

Elephant Sexual Sexual

Whiptail lizard Asexual Asexual

Parrot Sexual Sexual

Amoeba Asexual Asexual

Jellyfish Asexual Both

Conclusion:  

Your conclusion will include a summary of your lab results and an interpretation of the results. Please write in complete sentences.

1. List one-way mitosis and meiosis are the same and one way they are different.

Meiosis has 2 cell divisions, but mitosis has just one cell division. Since the parent cell develops diploid cells, meiosis I is the same as mitosis. The distinction between meiosis and mitosis is that after the whole process, meiosis produces genetically distinct haploid daughter cells, while mitosis produces genetically identical diploid daughter cells.

2. What is one advantage and one disadvantage of sexual reproduction?

The greatest benefit of sexual reproduction is that it aids in the development of offspring that are well suited to environmental environments due to genetic differentiation. As a result, the nation has a diverse range of descendants. The downside is that it needs two parents and takes longer than asexual reproduction.

3. What is one advantage and one disadvantage of asexual reproduction?

Asexual reproduction has the advantage of requiring only one parent, taking a short amount of time, and producing genetically identical offspring. The only drawback is that when there is a catastrophe, the mortality rate is poor due to the generation of genetically identical offspring.

4. Some living organisms are capable of both asexual and sexual reproduction. Explain how this can be an advantage.

To produce offspring, the organism may use either sexual or asexual reproduction. If it is difficult to find a mate, the living being will use asexual reproduction to produce offspring quickly. Sexual reproduction is possible because the individual requires genetically distinct offspring for survival.

List one way mitosis and meiosis are the same and one way they are different.

Meiosis has 2 cell divisions, but mitosis has just one process. Since the parent cell develops diploid cells, meiosis I is identical/ same as mitosis. The excellence between meiosis and mitosis is that after the complete process, meiosis produces genetically distinct haploid daughter cells, while mitosis produces genetically identical diploid daughter cells.

What is one advantage and one disadvantage of sexual reproduction?

Sexual reproduction is more efficient in its process of removing harmful mutations from the population. Although there will be offspring who don't survive due to the birth defects they encounter, it is a plus that protects the future of that species.

What is one advantage and one disadvantage of asexual reproduction?

A bad mutation can make asexually, produced organisms prone to disease and might destroy large numbers of offspring. Some methods of agamogenesis produce offspring that are close and compete for food and space.

Some living organisms are capable of both asexual and sexual reproduction. Explain how this can be an advantage.

An organism has many benefits for having the flexibility to breed both sexually and asexually. The primary of those benefits is that it doesn't need to find a mate so as to breed, so it can create offspring by itself, and enable the continuation of its species.

Answer:

They are placed on the periodic table based on their atomic number.

Explanation:

In the chemistry table, you can find the molecular mass and atomic number. Atomic number represents the number of the protons of an atom, and molecular mass represents the mass of the atom. The mass of an atom is made from proton and neutron. The element is made by arranging it based on the number of protons, which was the atomic number.

Answer:

When we put elements on the periodic table we use the atomic mass

Answer: Synthesis

0.84 moles of oxygen

25 moles of [tex]Fe_2O_3[/tex]

Explanation:

The balanced chemical equation is:

[tex]4Fe+3O_2\rightarrow 2Fe_2O_3[/tex]

This is a synthesis reaction as one product is formed by combination of two reactants.

According to stoichiometry :

a. 2 moles of [tex]Fe_2O_3[/tex] require = 3 moles of [tex]O_2[/tex]

Thus 0.56 moles of [tex]Fe_2O_3[/tex] require=[tex]\frac{3}{2}\times 0.56=0.84moles[/tex]  of [tex]O_2[/tex]

b. 4 moles of [tex]Fe[/tex] give = 2 moles of [tex]Fe_2O_3[/tex]  

Thus 50 moles of [tex]Fe[/tex] give =[tex]\frac{2}{4}\times 50=25moles[/tex]  of [tex]Fe_2O_3[/tex]

Explanation:

This is the job of the excretory system. You remove waste as a gas (carbon dioxide), as a liquid (urine and sweat), and as a solid. Excretion is the process of removing wastes and excess water from the body. Recall that carbon dioxide travels through the blood and is transferred to the lungs where it is exhaled.

Answer:

A) The solubility of NH3 increases, and the

solubility of KCl increases.

Explanation:

The solubility of ammonia and potassium chloride increases with decrease in temperature from 40°C to 20°C.

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

Answer:

1 mole is equal to 1 moles NaOH, or 39.99711 grams.

Explanation:

Hope this helps have a nice day :)

The statement of the mass of sodium hydroxide (NaOH) is "130 g."

A substance is something to do with mass that takes up space. The mass of a compound is the total amount of atoms present in grams that make up a molecule. The grams is the unit of mass.

In order to determine the mass in grams, multiply moles of the substance value by its molar mass to convert moles into grams.

Mole to gram conversion factor,

[tex]=\;given \;mole\;.\;\frac{grams}{1\;mol}[/tex]

Mass of NaOH comes out to be,

[tex]=\;3.25\;mol\;.\;\frac{39.997\;g}{1\;mol}[/tex]

= 129.99 g

= 130 g

Hence the correct answer is 130 g.

Answer:

A force pair is a couple of forces which are acting on any given body from opposite directions called action-reaction forces.

One can simply identify the force pair by identifying two objects which are interacting and by describing who is pushing whom and by identification of their drawing.

A book resting on table has two participants, a book applying force downwards due to gravity and the table pushing it away from the earth surface. These are action and reaction forces.
