How many moles of a gas would occupy 22.4 Liters at 273 K and 1 atm?
Read bottom comment
Answers
Answer:
The following relationship makes this possible: 1 mole of any gas at standard temperature and pressure (273 K and 1 atm) occupies a volume of 22.4 L.
Explanation:
1 mole of any gas would occupy 22.4L of gas at standard temperature and pressure (STP) i.e at 273K and 1 atm.
The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C (or 273 K) are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.
An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:
P V = n R T

How many grams of potassium chloride (KCl) can be produced from 180.6 g of chlorine (Cl2)?
Answers
Answer:
379.79 g of KCl
Explanation:
The balanced equation for the reaction is given below:
Cl₂ + 2KBr —> Br₂ + 2KCl
Next, we shall determine the mass of Cl₂ that reacted and the mass of KCl produced from the balanced equation. This can be obtained as follow:
Molar mass of Cl₂ = 70.90 g/mol
Mass of Cl₂ from the balanced equation = 1 × 70.90 = 70.90 g
Molar mass of KCl = 74.55 g/mol
Mass of KCl from the balanced equation = 2 × 74.55 = 149.1 g
SUMMARY:
From the balanced equation above,
70.90 g of Cl₂ reacted to produce 149.1 g of KCl.
Finally, we shall determine the mass of KCl produced by the reaction of 180.6 g of Cl₂. This can be obtained as follow:
From the balanced equation above,
70.90 g of Cl₂ reacted to produce 149.1 g of KCl.
Therefore, 180.6 g of Cl₂ will react to produce = (180.6 × 149.1)/70.90 = 379.79 g of KCl.
Thus, 379.79 g of KCl were obtained from the reaction.

Assignment Prompt
In this assignment, you will research the relationship between different types of energy when energy is
being transformed. You will present your findings in the form of bar graphs or pie charts that show the
forms of energy at different times in the process. You will then create a poster to display your findings.
Your poster should include a title, a brief description of the energy transformation you are showing, your
graphs, and works cited.
Assignment Instructions
Step 1: Gather materials and necessary information.
a) You will choose an energy transformation to show. Some of the ones you have learned about
include those that occur in a burning bonfire and a wind turbine.
• Do research to find out about an energy transformation that affects your daily life.
• Find out what the starting types of energy are and what the ending types of energy are.
• Decide how many steps in the process your poster will show.
• Create bar graphs or pie charts to show the relationship between the different types of
energy at different steps in the transformation process.
b) Be sure to keep a list of your references so you can cite them later.
Step 2: Decide on a title.
a) Begin by deciding on a title for your poster and writing it neatly at the top.
b) The title should identify the energy transformation you are showing.
Step 3: Create your graphs.
a) Decide how many graphs you will need to show the energy transformation.
b) You should have at least 3 graphs so that the steps of the transformation will be clear.
c) Each graph should be clearly labeled.
d) Careful use of color on your graphs will make them easy to read and understand.
Step 4: Decide on the descriptive words to include on your poster.
a) People looking at your poster may need more information than just the title and the
graphs. Decide on how you want to present the information your viewers need.
b) Keep the information as short as possible while still including what you need. Remember that
when people look at a poster, they focus on the graphics.
Step 5: Decide on the best layout for your poster.
a) You want to incorporate your text and visuals in a way that is attractive and attention-getting.
b) Keep your graphics as large as possible.
Step 6: Put your poster together.
Step 7: Cite your sources.
a) In the lower right-hand corner of your poster, create a section titled Works Cited.
b) List the resources you used to create your poster. A simple list of website titles and
addresses (URLs) is acceptable. If you used print sources, list the title, author, publisher, city,
and date. The print for this section can be small; it needs to be readable close-up.
Step 8: Identify yourself as the creator of the poster.
a) Place your name in the lower right-hand corner of the poster.
b) On the back, write your teacher’s name and the due date for the poster.
Step 9: Evaluate your poster using this checklist.
If you can check each criterion below, you are ready to submit your presentation.
Yes No Evaluation Question
Does your poster have a title that grabs interest and tells what your subject is?
Are the graphs clearly labeled?
Are the graphs bright and colorful?
Is the text on the poster clearly written so that the viewer understands what you are trying
to show?
Is it free from misspellings?
Is your poster laid out in a way that invites people to look at it?
Have you included your name and works cited?
Is your entire poster neat and attractive?
Step 10: Revise and submit your poster.
a) If you were unable to check off all the requirements on the checklist, revise your poster
before submitting it.
b) Ask your teacher for further instructions about presenting your poster to an audience of your
peers.

Answer:
Animal Cell Cytokinesis
Explanation:
Answer: Animal cell
Explanation:) It refers to the process of cell division, which takes place during mitosis, is known as cytokinesis.
The process of cytokinesis is different for animal cell and plant cell.
Where, in case of plant cell, a separation, known as cell plate is formed along the center of the parent cell, which is responsible for the separation of the cells.
Whereas, in case of animal cell, the plasma membrane contracts itself along the center, until the two daughter cells are separated from each other.
Hence, from the given information of the question,
The correct answer is animal cell.

At what temperature would a 1.30 m NaCl solution freeze, given that the van't Hoff factor for NaCl is 1.9? Kf for water is 1.86 ∘C/m .
Answers
Answer:
-4.59°C
Explanation:
Let's see the formula for freezing point depression.
ΔT = Kf . m . i
ΔT = Freezing T° of pure solvent - Freezing T° of solution
Kf = Freezing constant. For water if 1.86°C/m
m = molality (moles of solute in 1kg of solvent)
i = Van't Hoff factor.
0°C - Freezing T° of solution = 1.86°C /m . 1.30m . 1.9
Freezing T° of solution = - (1.86°C /m . 1.30m . 1.9)
Freezing T° of solution = - (1.86°C/m . 1.30m . 1.9) → -4.59°C

If 100 ml of a 0.5 M HCI Solution is diluted with water to 1000ml, what is the new concetration?
Answers
Answer:
[tex]0.05\ \text{M HCl}[/tex]
Explanation:
[tex]V_1[/tex] = Initial volume = 100 mL
[tex]V_2[/tex] = Final volume = 1000 mL
[tex]M_1[/tex] = Initial concentration = 0.5 M
[tex]M_2[/tex] = Final concentration
We have the relation
[tex]\dfrac{M_1}{M_2}=\dfrac{V_2}{V_1}\\\Rightarrow M_2=M_1\dfrac{V_1}{V_2}\\\Rightarrow M_2=0.5\times \dfrac{100}{1000}\\\Rightarrow M_2=0.05\ \text{M HCl}[/tex]
The new concentration is [tex]0.05\ \text{M HCl}[/tex].

How many bases of RNA represent an amino acid?
Answers
Answer:
three bases
Genetic experiments showed that an amino acid is in fact encoded by a group of three bases, or codon.
Explanation:
Hope this helps
In the given question, three bases of RNA represent an amino acid.
RNA (ribonucleic acid) is a molecule that plays an important role in protein synthesis. It carries genetic information from DNA to ribosomes, where it is used to direct the assembly of amino acids into proteins.
The genetic code is the set of rules by which the sequence of nucleotides in DNA or RNA is translated into the sequence of amino acids in a protein. The code is based on the sequence of three nucleotides, known as a codon, which specifies a particular amino acid.There are 64 possible codons, but only 20 amino acids that are used to build proteins. This means that some amino acids are specified by more than one codon. For example, the amino acid leucine can be specified by six different codons: UUA, UUG, CUU, CUC, CUA, and CUG.Therefore, three RNA bases represent an amino acid.

Answers
Answer:
Al(OH)- 4,
Explanation:
NaOH added to 0.010 M Al3+
The predominant species at equilibrium will be = Al(OH)- 4, and this because sodium hydroxide ( NaOH ) is a base will readily form a stable complex ion with aluminum ion like ( Al( OH ) - 4 . also the higher the Kf value the more stable the complex ion becomes and the more soluble Al(OH)3 becomes
hence the predominant species at equilibrium is : Al(OH)- 4,
