Answer:
4383.28 g
Explanation:
First we'll need to convert molecules into moles, we can do so using Avogadro's number:
6.0x10²⁵ molecules ÷ 6.023x10²³ molecules/mol = 99.62 molesThen we will convert 99.62 moles of carbon dioxide (CO₂) into grams, using its molar mass:
99.62 moles CO₂ * 44 g/mol = 4383.28 gSOMEONE HELP WITH THAT THING PLSSS( I also didn’t know what to put as the topic)

Explanation:
Water was on earth with the dinosaurs and almost at the very start.
Water starts anywhere from clouds to ponds
I choose ponds, water evaporates from the sun and moves its way through the air being collected into clouds in the atmosphere, clouds are evaporated water molecules, then the water combines to form rain wich then end up on a hill and travel back to a water source or goes into the ground and makes groundwater and if there is enough rain overtime will form a pond.
An element ceases to be that element if the particle it loses or gains is a neutron.
True or false
Answer:
False
Explanation:
An element is named according to the number of protons in the nucleus. If it gains or loses a neutron, it becomes a different isotope of the same element.
The given statement is false.

List and Describe the two groups of clastic sedimentary rock.
Answer:
Clastic sedimentary rocks are formed from rock fragments or clasts; chemical sedimentary rocks precipitate from fluids, and biochemical sedimentary rocks form as precipitation from living organisms.
Sedimentary rock is classified into two groups based on how they form. They are clastic and chemical. Clastic sedimentary rock is formed as bits of weathered rock become cemented together. Because all kinds of rock are subject to weathering many different minerals can make up this group of rocks.

How many moles of gas would be present in a gas trapped within a 37.0 L vessel at 80.00C at a pressure of 2.50 atm
go here is the answer key

According to ideal gas equation, there are 271472.7 moles of gas present in a gas trapped within a 37.0 L vessel at 80.0°C at a pressure of 2.50 atm.
What is mole?Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.
It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.
It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons .Molar mass has units of gram per mole . In case of molecules, where molar mass in grams present in one mole of atoms is its atomic mass.
Substitution of values in ideal gas equation gives,n= 2.5×37/8.314×353=271472.7 moles.

I am wondering how to find out the blood type of my grandson...my daughter is A+..father is in question...she is stressed to the max on the father of this baby boy.
Answer:
A person can identify their blood type at home using a rapid blood typing kit. Using the kit requires a person to pierce a finger with a needle. The kit comes with a card that contains chemicals known as reagents. These test for the presence of the antibodies and Rh factor.
Explanation:
Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.

Cytokinesis happens differently for plant and animal cells. Both separate cytoplasm between two new daughter cells. However, which type of cell cytokinesis looks like a balloon being separated by a string being pulled tightly between them?
Question 4 options:
Plant Cell cytokinesis
Animal Cell Cytokinesis
Both
Neither
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.

Determine the correct set-up below to determine what mass, in grams, of N2 is needed to completely react with 105 g F2 ?
Answer:
C: 1 mol F2/38 g F2
Explanation:
The reaction equation is;
N2 + 3F2 = 2NF3
Now, to know how many grams, of N2 is needed to completely react with 105 g F2 and since the molar mass of N2 is 28.02 g/mol, Molar mass of F2 is 38 g/mol, number of moles attached to N2 and F2 in the reaction are 1 and 3 moles respectively, then we will have;
105 g F2 × 1 mol F2/38 g F2 × 1 mol N2/3 mol F2 × 28.02 g N2/1 mol N2
Option C is Thus correct
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?

If 0.525 moles of O2 are produced, how many moles of KClO3 are decomposed?
Answer:
B. 0.35mol KClO3
Explanation:
The balanced equation in this question is given as follows:
2KClO3 → 2KCl + 3O2
Based on the chemical reaction;
2 moles of KClO3 decomposes into 3 moles of O2
If 0.525 moles of O2 are produced, then:
= 0.525 × 2/3
= 1.05/3
= 0.35mol of KClO3 is decomposed.
