List the 4 cell structures from largest to smallest
Answers
Answer: The smallest structure is the double helix while the largest is the chromosome.
2. G2 phase is the third stage in cellular division wherein the cell prepares itself for the M phase.
3. Interphase comprises of 3 phases, namely, G1 phase, G2 phase, and S phase.
4. Metaphase is known to take less amount of time to complete.
Explanation:
1. The double helix of the DNA or deoxyribonucleic acid, nucleosome, coil, supercoil, and the chromosomes are all linked to the DNA and they vary in their sizes. The nucleosome is known to be the basic unit of the eukaryotic chromosome that is composed of DNA coiled around the histones. The supercoils and coils indicate to the structures which are derived from the folding as well as wrapping of the structure of the DNA. The chromosome refers to the thread-like structure which is made up of nucleic acid and is observed in the nucleus of the living organisms.
2. Cell cycle refers to the cellular division of the cell; it is the series of events which occurs within a cell that results in duplication of the DNA or deoxyribonucleic acid as well as division of the cytoplasm and other organelles in order to generate two daughter cells. This cycle comprises of 4 phases, namely, G1, S, G2, and M phase.
The cell enters the G1 phase wherein the cell synthesizes the proteins as well as mRNA or messenger ribonucleic acid in preparation for the next upcoming phases which lead to mitosis. Next stage is the S phase wherein the synthesis of DNA takes place.
G2 phase is the next phase wherein the cell prepares itself by allowing it to grow as well as generate new proteins needed for the next phase called M phase. Mitosis is the final stage wherein the two identical daughter cells are made from one parent cell.
3. The cell cycle is broadly segregated into 3 phases, namely, interphase, M phase, and cytokinesis. Interphase is the longest stage of the cellular cycle and it comprises of 3 phases, G1 phase, S, and G2 phase. There is a G0 phase or quiescent phase. During the G1 phase, the cell prepares itself for the next phases of cell cycle, S phase involves synthesis of DNA, and G2 is the production of new proteins needed for the M phase.
4. During the mitotic phase, the parental cell segregates and produces 2 identical daughter cells. This phase is further segregated into prophase followed by metaphase, anaphase, and finally telophase. During metaphase, the chromosomes align themselves onto the equatorial or metaphase plate and the centrosomes prepare to segregate the sister chromatids. This phase takes only about 4% of the time needed to finish the entire cell cycle.

Over an interval of 2.0 s the average rate of change of the concentration of C was measured to be 0.0540 M/s. What is the final concentration of A at the end of this same interval if its concentration was initially 2.000 M
Answers
Answer:
Explanation:
the average rate of change of the concentration =
( initial concentration - final concentration ) / time
Initial concentration = 2.000 M
the average rate of change of the concentration = .0540 M/s
time = 2 s
Putting the values
.0540 = (2.000 - X ) / 2
0.108 = 2.000 - X
X = 1.892 M .
Final concentration = 1.892 M .

A)100cm^3
B)200cm^3
C)263cm^3
D)400cm^3
Answers
Answer:
236 cubic cm
Explanation:
We are given that
Initial volume, V1=200 cubic centimeter
Initial temperature, T1=60 degree Celsius=60+273=333 K
Final temperature, T2=120 degree Celsius=120+273=393 K
Kelvin temperature=Celsius temperature+273
We have to find the new volume of the balloon.
We know that
Charles's law
[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]
Using the formula
[tex]\frac{200}{333}=\frac{V_2}{393}[/tex]
[tex]V_2=\frac{200\times 393}{333}[/tex]
[tex]V_2=236cm^3[/tex]
Hence, the new volume of the balloon will be 236 cubic cm.

Why is it important to know gas properties at STP?
Answers
Answer:
STP values are most often cited for gases because their characteristics change dramatically with temperature and pressure. One common definition of STP is a temperature of 273 K (0° Celsius or 32° Fahrenheit) and the standard pressure of 1 atm. Under these conditions, one mole of a gas occupies 22.4 L.
g In science, we like to develop explanations that we can use to predict the outcome of events and phenomena. Try to develop an explanation that tells how much NaOH needs to be added to a beaker of HCl to cause the color to change. Your explanation can be something like: The color change will occur when [some amount] of NaOH is added because the color change occurs when [some condition]. The goal for your explanation is that it describes the outcome of this example, but can also be used to predict the outcome of other examples of this phenomenon. Here's an example explanation: The color of the solution will change when 40 ml of NaOH is added to a beaker of HCl because the color always changes when 40ml of base is added. Although this explanation works for this example, it probably won't work in examples where the flask contains a different amount of HCl, such as 30ml. Try to make an explanation that accurately predicts the outcome of other versions of this phenomenon.
Answers
Answer:
See explanation
Explanation:
A titration involves the addition of a titrant to an analyte solution. It is a method of volumetric analysis.
When a particular volume of titrant is added, the colour changes to signal the end point of the reaction.
The point at which the colour changes is called the equivalence point. This is the point at which the amount of titrant added is just enough to completely neutralize the analyte solution.
Hence the volume NaOH that needs to be added to the beaker containing HCl to cause a colour change is the volume of NaOH that is just enough to completely neutralize the HCl solution.

Oxidation of a dithiol such as 2,5-hexanedithiol forms a six-membered ring containing a disulfide group as part of the ring. Draw the structure of this cyclic disulfide (Hint: Draw the starting compound in line structure format first).
Answers
Answer:
See picture below
Explanation:
In general terms, oxidation of thiol are rather different than oxidations with alcohols.
A dithiol is a molecule that has two thiols in an organic compound. In the case of the 2,5 hexanedithiol, we have the thiols in the carbon 2 and carbon 5.
When oxidation of thiols occurs, and depending of the number of thiols in the molecule, the final compound will have a sulfide group.
This is because the oxydation makes that the hydrogen atom of the sulfur is substracted. So, in the case of the dithiols, we have that both hydrogen atoms are substracted and then, they are available to join. Therefore, As the thiols are in the same molecule, it will occur a self condensation reaction.
The picture below will show the final product.

Liquid hexane CH3CH24CH3 will react with gaseous oxygen O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O. Suppose 4.3 g of hexane is mixed with 25.8 g of oxygen. Calculate the maximum mass of carbon dioxide that could be produced by the chemical reaction. Round your answer to 2 significant digits.
Answers
Answer:
13g of CO₂ is the maximum amount that could be produced
Explanation:
The reaction of hexane with oxygen is:
C₆H₁₄ + 19/2O₂ → 6CO₂ + 7H₂O
Where 19/2 moles of oxygen react per mole of C₆H₁₄
To solve this question we need to find theoretical yield finding limiting reactant :
Moles C₆H₁₄:
4.3g C₆H₁₄ * (1mol / 86.18g) = 0.0499 moles
Moles O₂:
25.8g * (1mol / 32g) = 0.806 moles
For a complete reaction of 0.0499 moles of C₆H₁₄ are needed:
0.0499 moles of C₆H₁₄ * (19/2 mol O₂ / 1mol C₆H₁₄) = 0.474 moles of O₂.
As there are 0.806 moles, O₂ is in excess and C₆H₁₄ is limiting reactant
In theoretical yield, the moles of hexane added = 6Moles of CO₂ produced. Moles of CO₂ are:
0.0499 moles C₆H₁₄ * (6mol CO₂ / 1mol C₆H₁₄) = 0.299 moles CO₂
In grams:
0.299 moles CO₂ * (44.01g / mol) = 13g CO₂
13g of CO₂ is the maximum amount that could be produced

if a gas at 300k occupies 3.60 liters at a pressure of 1.00 atm, what will be it’s new pressure if the volume is compressed to 2.0 liters at a temperature of 450K?
Answers
Answer: The new pressure if the volume is compressed to 2.0 liters at a temperature of 450K is 2.7 atm
Explanation:
The combined gas equation is,
[tex]\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}[/tex]
where,
[tex]P_1[/tex] = initial pressure of gas = 1.00 atm
[tex]P_2[/tex] = final pressure of gas = ?
[tex]V_1[/tex] = initial volume of gas = 3.60 L
[tex]V_2[/tex] = final volume of gas = 2.0 L
[tex]T_1[/tex] = initial temperature of gas = [tex]300K[/tex]
[tex]T_2[/tex] = final temperature of gas = [tex]450K[/tex]
Now put all the given values in the above equation, we get:
[tex]\frac{1.00\times 3.60}{300}=\frac{P_2\times 2.0}{450}[/tex]
[tex]P_2=2.7atm[/tex]
The new pressure is 2.7 atm

In one experiment, the partial pressure of ammonia decreased from 21 kPa to 10 kPa in 770 s. (a) What is the rate constant for the zero-order reaction
Answers
Answer:
14.29 Pa/s
Explanation:
Given that, for a zero order reaction;
[A] = [A]o - kt
[A] = pressure at time =t
[A]o = initial pressure
k = rate constant
t = time taken
10 * 10^3 Pa = 21 * 10^3 Pa - 770k
10 * 10^3 Pa - 21 * 10^3 Pa = -770k
-11* 10^3 = -770k
k = -11* 10^3/-770
k = 14.29 Pa/s
