According to Wikipedia the average volume of a human flatulence event is 185ML if the average body temperature is 98.6°F in the atmospheric pressure is 760.0 tour how many moles of gas does the average fart contain
Answer:
0.00726mol
Explanation:
Using general gas equation,
PV = nRT
Where;
P = pressure
V = volume
n = number of moles
R = gas constant (0.0821 L atm mol/K)
T = temperature
First, we need to convert the units of each variable
Volume = 185mL = 0.185L
Pressure = 760.0 torr = 1 atm
Temperature = 98.6°F = 310.15K
PV = nRT
1 × 0.185 = n × 0.0821 × 310.15
0.185 = 25.46n
n = 0.185/25.46
n = 0.00726mol
If the work function of tin (Sn) is 281 nm, what equation could you use to determine the amount of energy required to eject a photoelectron from a sample of tin?
Answer:
See explanation
Explanation:
The work function is given by;
Wo = hc/λ
where;
h = 6.6 * 10^-34 Js
c = 3 * 10^8 ms-1
λ = 281 nm or 281 * 10^-9 m
Wo = 6.6 * 10^-34 * 3 * 10^8 / 281 * 10^-9
Wo = 7.0 * 10^-19 J or 4.375 eV
Note that the work function is the minimum energy required to eject an electron from a sample of tin.

Rank the following from most metallic to least metallic:
Cesium (Cs)
Iron (Fe)
Aluminum (AI)
Carbon (C)
Neon (Ne)
Answer:
Cs > Iron > Aluminum > Carbon > Neon
Explanation:
The most metallic from the given choices is Cesium and the least metallic is Neon.
Neon is noble gas and not a solid.
Metallic character of elements decreases across the period and increases with increasing electronegativity.
The most leftward element is Cesium and will be the most metallic. Neon has the least metallic character since it is a noble gas.
Cesium > Iron > Aluminum > Carbon > Neon

Ammonium chloride reacts with calcium oxide to produce ammonia, calcium chloride, and water. If 7.4 grams of ammonia are produced, how many grams of calcium chloride are also
produced?
Answer:
Mass of calcium chloride produced = 24.14 g
Explanation:
Given data:
Mass of ammonia produced = 7.4 g
Mass of calcium chloride produced = ?
Solution:
Chemical equation:
2NH₄Cl + CaO → 2NH₃ + H₂O + CaCl₂
Number of moles of ammonia produced:
Number of moles = mass/molar mass
Number of moles = 7.4 g/ 17 g/mol
Number of moles = 0.435 mol
Now we will compare the moles of ammonia and calcium chloride.
NH₃ : CaCl₂
2 : 1
0.435 : 1/2×0.435 = 0.2175 mol
Mass of calcium chloride produced:
Mass = number of moles × molar mass
Mass = 0.2175 mol ×110.98 g/mol
Mass = 24.14 g

Explanation:
A group of students removed the plastic insulation around a wire. They wrapped the uninsulated wire around a steel rivet 50 times in order to make an electromagnet. They connected the wires to a battery to make a complete circuit. They tried to pick up some steel washers, but nothing happened. Below is the advice they received from other groups in the class. What advice should they take to get their electromagnet to pick something up?
a . use insulated wire
b. wrap the wire around the nail more times
c. try picking up aluminum paper clips instead of the steel washers
d. add another d-cell to the circuit
Answer:
d. add another d-cell to the circuit
Explanation:
To make the electromagnet pick something, the student should add another d-cell to the circuit.
Simply, the electromagnet set up is generating very weak magnetic fields.
To produce an electromagnet, there must be an interaction between electric fields an conductor. As the wire turns around in the vicinity of the electric field, it induces magnetism. The number of turns of wire here is pretty considerable. But the electric field is very weak. Additional d-cell in the circuit will circumvent this problemwhat is the mass of element P which reacts with 1 .62g of element Q to form a compound with formula Q2p3
(relative atomic mass p,16;Q,27)
Mass of element P = 1.44 g
Further explanationProust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements
In the same compound, although from different sources and formed by different processes, it will still have the same composition/comparison
MW Q₂P₃ = 2.27 + 3.16=102 g/mol
Mass Q₂P₃ (MW=102 g/mol) :
[tex]\tt mass~Q_2P_3=\dfrac{MW~Q_2P_3}{2.Ar~Q}\times mass Q\\\\mass~Q_2P_3=\dfrac{102}{2\times 27}\times 1.62\\\\mass~Q_2P_3=3.06~g[/tex]
Mass P (Ar=16) :
[tex]\tt mass~P=\dfrac{3.Ar~P}{MW~Q_2P_3}\times mass~Q_2P_3\\\\mass~P=\dfrac{3.16}{102}\times 3.06\\\\mass~P=1.44~g[/tex]

The Top Thrill Dragster, a rollercoaster at Cedar Point in Ohio, soars through the air at 176ft/sec. How fast is this in mph?
The rollercoaster has a speed of 176 ft/sec. This can be converted to miles per hour. The speed is equivalent to 120 mph.
What is speed ?Speed is a physical quantity measuring the distance travelled by an object per unit time. Speed is a scalar quantity. The rate of speed is called velocity.
The speed can be expressed in different units. such as m/s, km/h, ft./s miles per hour etc. These units can be interconverted using specific relations.
One ft/s = 0.682 mph
then, 176 ft./s = 0.682 × 176 = 120 mph.
Therefore, the speed of the roller coaster is 120 mph.

how do the mass and height of an object affect the gravitational potential energy?
A. height has great a greater effect than mass gravitational potential energy
B. mass and height have the same effect on gravitational potential energy.
C. height has almost 10 times the effect on gravitational potential energy then mass has.
D. Mass has a greater effect than height on gravitational potential energy.
Answer:
B. mass and height have the same effect on gravitational potential energy.
Explanation:
Both mass and height have the same effect on the gravitational potential energy of body.
Gravitational potential energy is the energy of a body due to that of another body. It usually the energy at rest in a body.
It is mathematically expressed as;
G.P.E = m x g x h
m is the mass
g is the acceleration due to gravity
h is the height
We see that both the height and mass are directly proportional to the gravitational potential energy and as such, they have the same effect.
Iridium has two naturally occurring isotopes, Iridium-191 and Iridium-193. If the average atomic mass of orodum s 192.217, what are the average percent abundances of each isotope?
Answer:
The percent isotopic abundance of Ir-193 is 60.85 %
The percent isotopic abundance of Ir-191 is 39.15 %
Explanation:
we know there are two naturally occurring isotopes of iridium, Ir-191 and Ir-193
First of all we will set the fraction for both isotopes
X for the isotopes having mass 193
1-x for isotopes having mass 191
The average atomic mass is 192.217
we will use the following equation,
193x + 191(1-x) = 192.217
193x + 191 - 191x = 192.217
193x- 191x = 192.217 - 191
2x = 1.217
x= 1.217/2
x= 0.6085
0.6085 × 100 = 60.85 %
60.85% is abundance of Ir-193 because we solve the fraction x.
now we will calculate the abundance of Ir-191.
(1-x)
1-0.6085 =0.3915
0.3915× 100= 39.15 %
Atmospheric pressure on the peak of Mt. Everest can be as low as 150 mm
Hg, which is why climbers need to bring oxygen tanks for the last part of
the climb. If the climbers carry 10.0 liter tanks with an internal gas
pressure of 30400 mm Hg, what will be the volume of the gas when it is
released from the tanks?
Answer:
Volume of gas when release form tank = V₂ = 2026.67 L
Explanation:
Given data:
Initial volume of gas =V₁= 10.0 L
Pressure of gas inside tank =P₁= 30400 mmHg
Volume of gas when release form tank =V₂= ?
Pressure at peak =P₂= 150 mmHg
Solution:
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
30400 mmHg × 10.0 L = 150 mmHg × V₂
V₂ = 304000 mmHg. L/ 150 mmHg
V₂ = 2026.67 L
what volume is occupied by5.3 mol of c02 at 28c and a pressure of .998 atm
Answer:
V = 131.23 L
Explanation:
Given data:
Moles of CO₂ = 5.3 mol
Temperature = 28°C
Pressure = 0.998 atm
Volume occupied = ?
Solution:
Formula:
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will convert the temperature.
28+273 = 301 K
0.998 atm ×V = 5.3 mol × 0.0821 atm.L/ mol.K × 301 K
V = 130.97 atm.L / 0.998 atm
V = 131.23 L
Increasing temperature increases the number of collisions and the potential energy of the colliding molecules and
decreases the reaction rate.
