please help!! i don’t know what the heck im doing lol
Answer:
I can help you know how to mark the points.
For the first one point, if you look at the lines that go side to side, you need to find the line that is 20 degrees that's above the blue line. Next, if you look at the lines that go up and down, you need to find the line that is 30 degrees, but is to the right of the blue line. When you plot your point, it should somewhere along the coastline of Saudi Arabia.
For the second point, if you look at the lines that go side to side, you need to find the line that's 40 degrees that's below the blue line. Next, if you look at the lines that go up and down, you need to find the line that is 10 degrees that's to the left of the blue line. When you plot your point, it should be located somewhere in the South Atlantic Ocean.
For the third point, if you look at the lines that go side to side, you need to find the line that's 20 degrees that's below the blue line. Next, if you look at the lines that go up and down, you need to find the line that's 40 degrees that's to the right of the blue line. When you plot your point, it should be kind of located in the Indian Ocean, but not too far from Africa.

Picture:
Be sure to answer all parts. Show the overall reaction for formation of racemic 3−bromohexane from (E)−3−hexene by entering the structures of the products and reactants in the template provided. Part 1 out of 3 draw structure ... arr draw structure ... + draw structure ... (E)−3−hexene (S)−3−bromohexane (R)−3−bromohexane Racemic product = 50% (S) and 50% (R)
Answer:
See explanation
Explanation:
The mechanism for the formation of bromohexane from hexene has been clearly shown in the image attached to this answer.
Hexene is attacked by HBr and a carbocation is first formed as shown. The carbocation is flat and planar. it can be attacked on either face by the bromide ion.
Attack on either faces yields a racemic mixture of the R and S enantiomer as shown in the image.
You can use the mechanism shown to fill in the structures.
the correct electron-dot formula for a molecule of chlorine?
Answer:
Cl has 7 dots
if its Cl2; Cl-Cl it will contain 14 dots
Explanation:
The electron-dot formula of the chlorine molecule Cl₂is shown in the attached diagram below.
What is the lewis electron dot diagram?A lewis electron dot structure is used to represent the number of bonds, the bonding atoms, and the lone pairs left in the atoms in the molecule.
Lines are shown between atoms that are bonded to one another and excess electrons or lone pairs are represented as dot pairs and are placed next to the atoms.
As the valence electrons of each chlorine atom are equal to seven from the electronic configuration of the chlorine atom.
First, the total number of valence electrons in a chlorine molecule is 7 + 7 = 14.
As each chlorine atom needs only one electron to complete its octet. As the octet completes, the rest of the electrons are assigned as the lone pairs of atoms. Therefore, each chlorine atom has three lone pairs of electrons on it.

The relationship between Fahrenheit and Celsius is as follows: °F = °C * 1.8 + 32 If the weather forecaster says it will be 14 °F, what is that in Celsius?
Answer:
The answer is "-10° C".
Explanation:
Fahrenheit and Celsius, both use scales for measuring their temperature standard. The Fahrenheit suggests, as just a cold water point by taking 32° F and hot water rate by taking 212° F. The freezing temperature of both the water at the Celsius scale is 0° C, as well as the boiling point of its water at 100° C.
Converting the Fahrenheit to Celsius:
Formula: [tex]\bold{^{\circ}F = ^{\circ}C \times 1.8 + 32}[/tex]
°F= 14
[tex]\to 14 = ^{\circ}C \times 1.8 + 32}\\\\\to 14 -32 = ^{\circ}C \times 1.8 \\\\\to -18 = ^{\circ}C \times 1.8 \\\\\to ^{\circ}C = \frac{-18}{1.8} \\\\\to ^{\circ}C = \frac{-180}{18} \\\\\to ^{\circ}C = - 10[/tex]

the properties of ionic compounds. Describe the
general properties of ionic compounds.
Answer:
Explanation:
Lattice energy is a way to measure the bond strength in ionic compounds. Ionic compounds tend to have high melting and boiling points. Ionic compounds tend to be hard. Ionic compounds have a range of solubilities.
A 15.0 L tank of gas contained at a high pressure of 8.20 • 10^4 torr. The tank is opened and the gas expands into an empty chamber with a volume of 600•10^4 L. Calculate the new pressure of the gas
Answer:
P₂ = 0.205torr
Explanation:
Boyle's law relates the pressure and volume of a gas under two different conditions. The equation is:
P₁V₁ = P₂V₂
Where P is pressure and V volume of of 1, initial conditions and 2, final conditions.
P₂ is our incognite
Replacing:
P₁V₁ = P₂V₂
8.20x10⁴torr*15.0L = P₂*600x10⁴L
P₂ = 0.205torr
What is the energy of a microwave photon that has a frequency of 9.86 x 1012 Hz?
Answer:
E = 65.37×10⁻²² J
Explanation:
Given data:
Energy of photon = ?
Frequency of photon = 9.86×10¹² Hz
Solution:
Formula:
E = h.f
Here h is planck's constant its value is 6.63×10⁻³⁴ js.
E = 6.63×10⁻³⁴ js × 9.86×10¹² Hz
Hz = s⁻¹

A gas that occupies 50.0 liters has its volume increased to 68 liters when the pressure was changed to 3.0 ATM. What was the original pressure of the gas in ATM? In mmHg? In kPa?
Answer:
4.1 atm = 3,116 mmHg = 415.4 kPa
Explanation:
According to Boyle's law, as volume is increased the pressure of the gas is decreased. That can be expressed as:
P₁ x V₁= P₂ x V₂
Where P₁ and V₁ are the initial pressure and volume respectively, and P₂ and V₂ are final pressure and volume, respectively.
From the problem, we have:
V₁= 50.0 L
V₂= 68.0 L
P₂= 3.0 atm
Thus, we calculate the initial pressure as follows:
P₁= (P₂ x V₂)/V₁= (3.0 atm x 68.0 L)/(50.0 L)= 4.08 atm ≅ 4.1 atm
To transform to mmHg, we know that 1 atm= 760 mmHg:
4.1 atm x 760 mmHg/1 atm = 3,116 mmHg
To transform to kPa we use: 1 atm= 101.325 kPa
4.1 atm x 101.325 kPa = 415.4 kPa

A steel cylinder for scuba diving contains 11.1 L of compressed air. The pressure inside the cylinder is
204 atm at a temperature of 24°C.
Calculate the number of moles of air in the cylinder.
Write your answer using three significant figures.
mol air
Answer:
9.28moles
Explanation:
Given parameters:
volume = 11.1L
pressure = 204atm
temperature = 24°C = 24 + 273 = 297K
Unknown:
Number of moles of air in the cylinder = ?
Solution:
To solve this problem, we apply the ideal gas equation;
PV = nRT
P is the pressure
V is the volume
n is the number of moles
R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹
T is the temperature
Now insert the parameters and find n;
204 x 11.1 = n x 0.082 x 297
226.4 = 24.4n
n = 9.28moles
The number of moles of air in the cylinder is 92.98 moles
From the following parameters given, we are to determine the number of moles of air in the cylinder.
Given that:
The volume of the steel cylinder = 11.1 LThe pressure inside the cylinder = 204 atmThe temperature inside the cylinder = 24°CThe number of moles of air can be determined by using the relation for the ideal gas equation which can be expressed as:
PV = nRTwhere
n = number of molesMaking (n) the subject of the formula:
[tex]\mathbf{n = \dfrac{PV}{RT}}[/tex]
[tex]\mathbf{n = \dfrac{204 \ atm \times 11.1 L}{0.082 \ L .atm/mol .K \times 297 \ K}}[/tex]
n = 92.98 moles

Which model of the atom was used as a result of JJ Thomson's cathode ray

a. Plum pudding model
b. Nuclear model
C. Planetary model
d. Quantum mechanical model
Answer:
a. Plum pudding model
Explanation:
The plum pudding model of the atom was proposed by J.J. Thomson. It was the model he derived from his experiment on the gas discharge tube.
J.J Thomson was the first person to discover electrons which he called cathode rays because in the discharge tube, they emanate from the cathode.
This led him to suggest the plum pudding model of the atom. The model reflects electrons being surrounded by a volume of negative charges.Write 2.0 x 10^-3 in standard notation
