In the atmosphere, it is more common to find two oxygen molecules joined together than to find a single atom of oxygen. Why? What would that molecule look like? What would this molecule be called?
Answers
Answer:
See explanation
Explanation:
Oxygen has six electrons in its outermost shell. This means that its octet can be completed when it shares two electrons with another oxygen atom.
In a covalent bond, each bonding atom contributes one electron to the bond. This means that four electrons are shared between two oxygen atoms. Each atom contributes a total of two electrons which are shared. This molecule of oxygen satisfies the octet rule rather than a single atom of oxygen.
An image of the oxygen molecule is attached to this answer.
This system of two oxygen atoms joined together in a covalent bond is called an oxygen molecule(O2).

Given the balanced equation: 4Fe(s) + 30₂(g) → 2Fe₂O₃(s) + 1640 kJ Which phrase best describes this reaction?
A) endothermic with AH = +1640 kJ
B) endothermic with AH =-1640 kJ
C) exothermic with AH= +1640 kJ
D) exothermic with AH = -1640 k
Answers
Answer:
yeah the answer under the explanation
Explanation:
The answer is (4) exothermic with ΔH = -1640 kJ. The 1640 kJ energy is at the right side of equation means that it releases energy. The enthalpy change means the energy of production minus the energy of reactants. If it is exothermic, the ΔH < 0.

a.What distance did I travel?
b. What's my displacement?
Answers
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.

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.

Suppose Rutherford's lab was 10 meters (m) long and the speed of an alpha particle is 3.0x10^8 meters per second (m/s). How much time would he plan on the alpha particles taking to move from the alpha particle source to the gold foil target? Write it in a mathematical equation
Answers
Answer:
t = d/v , 33.3 ns
Explanation:
Since distance, d = vt where v = speed and t = time taken to cover the distance.
Since the distance, d covered by the alpha particle is the length of Rutherford's lab which is 10 m long and the speed of the alpha particle is v = 3 × 10⁸ m/s, the time, t it takes the alpha particle to move from the alpha particle source to the gold foil target is thus
t = d/v
= 10 m/3 × 10⁸ m/s
= 10/3 × 10⁻⁸ s
= 3.33 × 10⁻⁸ s
= 33.3 × 10⁻⁹ s
= 33.3 ns

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.

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.

What is a cone of depression and how is it caused?

Explanation:
hope this helps a bit :)
When a well is pumped, the water level in the well is lowered. By lowering this water level, a gradient occurs between the water in the surrounding aquifer and the water in the well. Because water flows from high to low water levels or pressure, this gradient produces a flow from the surrounding aquifer into the well.
As the water flows into the well, the water levels or pressure in the aquifer around the well decrease. The amount of this decline becomes less with distance from the well, resulting in a cone-shaped depression radiating away from the well. This, in appearance, is similar to the effect one sees when the plug is pulled from a bathtub. This conical-shaped feature is the cone of depression.

0.25 M
0.43 M
4.27 M
Answers
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]

To write a molecular formula , the following steps are usually adopted only when we know the symbol and valencies of elements and radicals present in a molecule.
Step 1 : First , the name of the compound is written.
Step 2 : The symbols of basic and acidic radicals are written side by side.
Step 3 : The valency of each radical is written at the right upper corner of the symbol. The valency of one radical is transferred to another radical and it is written on the right hand side at the bottom corner. If necessary , L.C.M of the valencies us taken to get a simple whole number.
Step 4 : If a compound radical takes part in the molecular formula , the radical is enclosed in brackets and the valency number is written on the right side of the bracket at the bottom of the formula.
For instance :
[tex] \text{Calcium \: \: \: \: \: \: Sulphate}[/tex] [ compound ]
1. [tex] \sf{Ca \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: SO_{4} }[/tex] [ Symbol of basic and acidic radicals ]
