What is the osmotic pressure in atm of
a 0.50 M urea solution at 25.0°C?
Assume R = 0.0821 Latm/molk
Enter text here
Answer:
12.2329 atm
Explanation:
Applying
PV = nRT.................... Equation 1
Make P the subject of the equation
P = (n/V)RT................ Equation 2
Where P = Osmotic pressure, (n/V) = Molarity of urea, T = Temperature, R = molar gas constant.
From the question,
Given: (n/V) = 0.5 M, T = 25°C = (273+25) = 298 K, R = 0.0821 Latm/mol.K
Substitute these values into equation 2
P = (0.5)(298)(0.0821)
P = 12.2329 atm
Seismic station A is 5000 kilometers from the epicenter. What is the difference between the arrival time of the first P-wave and the arrival time of the first S-wave recorded at this station?
2 minutes 20 seconds
6 minutes 40 seconds
8 minutes 20 seconds
15 minutes 00 second
Answer:
6 min 40 sec
Explanation:
Hope this helps you :)
The difference between the arrival time of the first P-wave and the arrival time of the first S-wave recorded at the station will be 6 minutes 40 seconds.
What are Body waves ?P waves move the fastest and arrive first from the earthquake. Rock oscillates perpendicular to the direction of wave propagation in S or shear waves.
In rock, S waves move at approximately 60% the speed of P waves, and the S wave always comes after the P wave. Sound waves, for example, are P waves with a high enough frequency to be heard with your ear.
Wiggling or shaking a rope that is tied down at one or both ends is an example of a S wave.
Both P and S waves propagate outward from an earthquake focal point within the ground.
The waves are frequently observed as independent arrivals on seismographs located at great distances from the earthquake. The direct P wave arrives first because its course takes it through faster moving, denser rocks deeper in the ground.
Because they pass through deeper, lower velocity rocks, the PP (one bounce) and PPP (two bounces) waves move more slowly than the straight P. After the P waves, the various S waves arrive.
To conclude with we can say that Seismic waves or body waves are elastic waves created when the earth's crust is disturbed. The wave is classified into two types body waves and surface waves. The P and S - waves that move through the ground are body waves.

its BalancingChemEquations part B gizmo
Answer:
For the second to last problem the coefficients is 1, 5, 3, and 4 and the last problem all the coefficients are 1's
Explanation:
For the second to last problem you put 3 next to CO₂ so C is 3 on both sides. Then you put 4 next to H₂O because H will then be 8 on both sides. Lastly you put 5 next to O₂ which will make 10 on the reactant side. On the product side the 3 next to CO₂ will make O on the product side 6 and the 4 next to H₂O will make O on the product side 4. You will then add both together and it will make 10, which will make 10 on both sides. Hope this helps!

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?

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).
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.

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.
