How many molecules are found in 3.4 moles of carbon dioxide?
Please help me asap! :0
Thank you!
Answer:
One mole of anything has 6.023 x 10^23 molecules.
That would mean 3.4moles of CO2 have 6.023x 10^23 times 3.0.
So that would be2.04782×10^24 molecules in 3.0 moles of C02.
Mole measure the number of elementary entities of a given substance that are present in a given sample. 2.047×10²⁴ molecules are found in 3.4 moles of carbon dioxide.
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.
Mathematically,
number of molecules of carbon dioxide = number of moles of carbon dioxide ×6.022×10²³ molecules
Number of moles of carbon dioxide=3.4moles
Substituting the values in the above equation we get
number of molecules of carbon dioxide =3.4moles×6.022×10²³ molecules
number of molecules of carbon dioxide =2.047×10²⁴
Therefore, 2.047×10²⁴ molecules are found in 3.4 moles of carbon dioxide.

explain how rain gauge measures the amount of rainfall
A rain gauge is really just a cylinder that catches rain. If an inch collects in the cylinder, it means an inch of rain has fallen. It's that simple. Most standard rain gauges have a wide funnel leading into the cylinder and are calibrated so that one-tenth of an inch of rain measures one inch when it collects inside.

What is the molarity of a solution when 2.75 g of NaCl is dissolved in 1100 mL of solution?
0.043 M
0.25 M
0.43 M
4.27 M
Answer:
Explanation:
0.25 M
The molarity of a solution will be 4.27M .
What is molarity?Molarity (M), often known as molar concentration, is the concentration of a solution expressed in moles of solute per liter of solution.
What is solution?Solution can be considered as a mixture of more than one component. It may be homogeneous solution as well as heterogeneous solution.
Gram to mole conversion:
[tex]=\;2.75\;g.\;\frac{1\;mol}{58.44g} \\=\;0.0470 \;mol[/tex]
Molarity of the solution can be calculated by using the following formula:
It is calculated that, moles of solute = 0.0470 mol, volume of the solution = 1100 mL.
Now, put the value of given data in molarity formula:
[tex]Molarity=\frac{Moles\;of\;the\;solute}{Volume \;of\; the\; solution} \\=\frac{0.0470\;mol}{1100 \;mL} \\=\;4.27\;mol/mL\\=\;4.27\; M[/tex]
Therefore, the molarity of a solution will be 4.27M.

I need help with this for an assignment
I went for a walk the other day. I went four blocks east, then seven blocks south, then one block west and finally
eight blocks north
a.What distance did I travel?
b. What's my displacement?
Answer:
a) distance is 4+7+1+8=20 blocks
b) displacement is 10 blocks
Explanation:
find displacement: x and y
x axis displacement = 4-1 = 3 blocks
y axis displacement = -7+8= 1 block
displacement = the square root of 3^2 + 1^2
= 9+1 = 10 blocks.
You can find the angle of displacement with respect to the initial position using trig identities, if you wish.

Atomic models are important because, they help us visualize the interior of atoms and molecules, and thereby predicting properties of matter.
Explanation:
We study the various atomic models in our course of study because, it is important for us to know, how did people come to the present concept of an atom. How did physics evolve from classical to quantum physics.
All these are important for us to know and thus, knowledge about various atomic models, their discoveries and drawbacks and finally improvements based on scientific evidence present at that time is important for us to understand the underlying theory very well.

A DAY IN THE LIFE OF METIS JOURNAL. I WROTE IT HOPE U LIKE IT XD
We, who live in the west, were Nomadic. So we always moved from place to place to hunt buffalo and other fur-bearing animals. And now again we have to shift everything we collected , like, all the essential needs we collected. It’s really hard to shift stuff, But when you move to a new place you get to see new beautiful places. They are just so satisfying to see! It’s like all my work(like the shifting work) is paid off. I love it! We always meet the Hudson’s bay company employees, and give them furs which we took from the bissons and other furry animals we hunted. And in exchange they give us their (Hudson’s Bay company) goods. Which is good! Because then we or I won't be able to enjoy that delicious pemmican!
The one reason that makes me proud of my parents is that because of them I am like a translator for both sides in the fur trade! Anyways coming back to the present. As I said before, we were moving today to another place, But on the way some people along with my father will ride the famous York boats carrying supplies to fur posts. I begged my father to take me with him! And as usual he gave me some silly reason for me to stay. And now since I don’t have anything to do I will-..Nevermind, My mom’s calling me. Okay after helping my mom keep the fur posts into the York boats me , my mom, and the others are just relaxing and enjoying nature just to take a break. Since, I am so obsessed with my Journal notebook today I’m just going to sit here and right what comes to my mind. I’m not like the others who always seem to be talking with someone. I like my own space!
I kind of miss my dad already, but he and his fellow members need to travel the waterways from the red river further west and north to hudson bay. These red river carts also travel the trek back and forth over land to St. Paul, Minnesota and to posts in saskatchewan. Speaking about the red river, the only large settlement in the region is the red colony. About 12000 people lived in this colony around Fort Garry. Some were the original Selkirk settlers or their descendents. They had come from Scotland with lord Selkirk when he established the colony in 1811. Many of these original settlers were poor farmers who had been displaced from their lands in scotland. They had endured many hardships in the early years of settlement, including foods, hunger, and sickness. I love studying about other colonies, cultures , history etc.

The diagram shows a 21.7kg ball located on a shelf 1.6m above the ground. Which best describes the energy
of the ball?
o C. It has mechanical energy in the form of potential energy
O A. Its energy is lost once it falls off the shelf.
O B. Its energy depends upon the speed the ball will travel.
O D. It has mechanical energy in the form of kinetic energy.
Answer:
c
Explanation:
The ball of 21.7 kg which is located on a shelf 1.6 m above ground is having a mechanical energy in the form of potential energy. Hence, C best describes the energy of the ball.
What is potential energy ?Potential energy is the energy stored on it when the object is at rest. Kinetic energy of an object is generated by virtue of its motion. When a body starts moving its potential energy starts converts to kinetic energy.
The sum of kinetic and potential energy of an object is called its mechanical energy. An object has mechanical energy in the form of kinetic energy when it is at rest. When it starts to move its potential energy converts to kinetic energy.
Therefore, the ball of 21.7 kg placed in the shelf of height 1.6 m has a potential energy as long as it stays there on the shelf. Its potential energy = mgh
p = 21.7 kg × 9.8 m/s² × 1.6 m = 340.25 J

Answer:
Which of the following MOST influences a major
shift in how the entire nucleotide sequence is
read?
А base-pair substitutions and point mutationsB silent mutations and nonfunctioning proteins
С missense mutations and nonsense mutations
D base-pair insertions and deletions
Among the given disorders, missense mutations and nonsense mutations which mostly influences the shift in entire nucleotide.
What is mutation?A nucleotide is made of ribose sugar, phosphate groups and base pairs. Each base have a complementary base to which it pairs. If any disorder occurs in the base pairing or coding in nucleotide it is called the mutation.
A missense mutation is a sort of point mutation or single base mutation that alters the DNA by replacing one nucleotide of the codon with another nucleotide, thus changing the amino acid that is coded for in the protein.
A nonfunctional protein may emerge from the substitution of an amino acid, or the protein may not be impacted at all. Whether the mutational alterations are "conservative" or "nonconservative" will determine the functionality of the resulting protein.
It's interesting to note that the mutation is known as a nonsense mutation when the alteration in the codons nucleotide causes the development of the stop codon. The nonsense mutation causes the premature end of protein synthesis as a result of the creation of the stop codon.
