Answer:
Option B
The atmospheric pressure at sea level is higher.
Explanation:
Atmospheric pressure can simply be understood as the weight of the air molecules in the atmosphere. The higher we go up into the atmosphere, the thinner the air becomes. This means that the air present at higher heights is not so much, and hence, the air is lighter. This is why most fighter jets and mountain climbers need oxygen tanks to breathe properly.
Due to the fact that the air is less dense (lighter) at higher altitudes, it also means that the atmospheric pressure at higher altitudes is less.
Therefore, the atmospheric pressure at the sea level is higher than the atmospheric pressure at altitudes above sea level
Answer:
B. The atmospheric pressure at sea level is higher.

What us the % composition of oxygen (O) in iron (III) hydroxide, Fe(OH)
3?
Answer:
44.91% of Oxygen in Iron (III) hydroxide
Explanation:
To solve this question we must find the molar mass of Fe(OH)3 and the molar mass of the oxygen in this molecule. Percent composition will be:
Molar mass Oxygen / molar mass Fe(OH)3 * 100
Molar mass Fe(OH)3 and oxygen:
1Fe = 55.845g/mol*1 = 55.845
3O = 16.00g/mol*3 = 48.00 - Molar mass of Oxygen
3H = 1.008g/mol*3 = 3.024
55.845 + 48.00 + 3.024 =
106.869g/mol is molar mass of Fe(OH)3
% Composition of oxygen is:
48.00g/mol / 106.869g/mol * 100 =
44.91% of Oxygen in Iron (III) hydroxideWhat is the definition of a commission? * 4 points Earnings based on how much they sell What you are paid to work. When you are paid to work on a mission as a coworker.
Answer:
Earnings based on how much they sell
Explanation:
A sales presentation can be defined as series of talk given by a salesperson with the attempt to persuade someone or a potential customer to buy a particular product, by giving information it. Some salespersons resort to the use of dramatics so as to initiate and close the sale of a particular product by engaging in series of theatrical actions.
In sales and marketing, the term closing with respect to a sales can be defined as the process of making a business sale successful such as through the exchange of money for a particular product or goods.
For a salesperson to be able to close a sales, he or she require abilities such as courage, negotiation skills, listening ears and interpersonal skills to do so or achieve a successful sales. After a successful sales, they're entitled to a percentage of the amount made from selling a particular product or closing a deal based on what is stated in the contract. These amount of money earned with respect to each sales is generally referred to as commissions.
Commission can be defined as an amount of money earned based on how much a salesperson sell.
Define molarity of a solution.
Answer:
Molarity of a solution is defined as

How many days does it take 16.Og of Gold-198 to decay to 1.0g? (each half-
life = 2.69 days) *
O 10 days
0 2.69 days
O 10.76 days
16 days
PLZ HELP NOW
Answer:
10.8 days (3 sig.figs.)
Explanation:
All radioactive decay is 1st order decay defined by the expression A = A₀e^-kt
which is solved for time of decay (t) => t = ln(A/A₀) / -k
A = final weight = 1.0 gram
A₀ = initial weight = 16.0 grams
k = rate constant = 0.693/t(1/2) = 0.693/2.69 days = 0.258 days⁻¹
t = ln(1/16) / -0.258da⁻¹ = (-2.77/-0.258) days = 10.74646792 days (calculator)
≅ 10 days (1 sig. fig. based on given 1 gram mass)
Explain the energy flowing as you hold an ice cream cone. (Be sure to mention "the system," "the surroundings," and how energy is being transferred.)
Answer:
This is what I put, it hasn't been graded though...
Within the system, the energy is flowing from your hand to the ice cream cone. Energy is also flowing from the surroundings to the ice cream cone unless it's reeeeaally cold in the surroundings in which case why are you even holding an ice cream cone when it's that cold?

What is the total number of atoms present in 5Na,PO.?
Answer:
3.01×10²⁴ atoms
Explanation:
Our compound is the Na₃PO₄
Sodium phosphate.
We assume, we have 5 moles of the mentioned salt.
1 mol of anything contains 6.02×10²³ atoms.
That's the Avogadro's number. The conversion is:
5 mol . 6.02×10²³ atoms /1mol = 3.01×10²⁴ atoms

If nitrogen at 130 kPa is allowed to expand at constant temperature until its pressure is 145.5 kPa, how much larger will the volume become?
Answer:
0.89 times
Explanation:
Let the initial volume of the tank be V.
Finally, we shall determine how much larger the final volume of the gas will be. This is illustrated below:
Initial pressure (P₁) = 130 kPa
Initial volume (V₁) = V
Final pressure (P₂) = 145.5 kPa
Final volume (V₂) =?
P₁V₁ = P₂V₂
130 × V = 145.5 × V₂
130V = 145.5 × V₂
Divide both side by 145.5
V₂ = 130V / 145.5
V₂ = 0.89V
Therefore, the final volume of gas will be 0.89 times the initial volume.
Which best describes the velocity of a person on a merry-go-round? * 1 point zero constant increasing continuously changing
Answer:
continuously changing
Explanation:
The velocity of a person on a merry-go-round can best be described as continuously changing. This is because the initial velocity before the ride starts would be 0. Once the ride begins, it keeps going faster and faster until it reaches a certain speed. During this time the velocity is increasing. Then it remains constant for a certain period of time and when the ride is over the velocity and speed begins to decrease until ultimately reaching a speed of 0. Therefore, it is continuously changing throughout the duration of the ride.

how many grams of C are in 500g or NaHCO3
Answer: 71.43g
Explanation: The RMM of NaHCO3 is
23+1+12+16(3)=84.
There is one carbon in NaHCO3 thus there are 1×12g of C in NaHCO3.
Thus
85gNaHCO3-----12g C
500gNaHCO3---- xgram
(500×12)÷84= 71.43
Is cannabinol soluble in 1-octanol?
Why or why not?
Answer: Uhmmmm this is what i got...-
Explanation:
It is a matter of fact that the hydrophobic (water-hating) oily compounds of cannabinoids such as CBD, THC and others are not water soluble. The term "water soluble" refers to materials which dissolve in water in a homogenous manner by becoming molecules or ions (such as sugar, alcohol, and salt).

positively charged nulceus surrounded by a large void filled with only a few electrons orbiting the nucleus.
What other experiment or evidence assisted in the creation of this model?
A)
Electrons in orbit would be captured by a nucleus.
B)
The precise location of an electron is impossible to acertain.
o
The plum pudding model of the atom agreed with the nuclear model
D)
Thomson discovered the atom contained negatively charged electrons.
Nature of Science
SC6N22) New Evidence
ID:7495
Answer:
The plum pudding model of the atom agreed with the nuclear model
Explanation:
Answer:
D) Thomson discovered the atom contained negatively charged electrons.
Explanation:
Without previous discoveries such as the electron, Rutherford would not have generated his nuclear model. So, Thomson had to discover the atom contained negatively charged electrons first.
