Use the ideal gas law:
<em>PV=nRT
</em>p = pressure
v = volume
n = number of moles of sample
R = ideal gas constant = ~0.08206 (l*atm)/(K*mole)
T = Temp in Kelvin
Now we substitute while simultaneously solving for P(pressure)
P = (nRT)/V
P = (2.50 * 0.08206 * (27+273.15)) / 50
P = Now it's your turn.
Answer:
A scientist is studying a shock wave from an earthquake, he is studying mechanical wave.
Explanation:
The shock waves are experienced during earthquake. At the area of increased pressure shock wave are created as the object in that places moves faster as compared to the speed of sound. Shock wave are type of mechanical wave. For its transfer it requires a medium. An electromagnetic wave can travel of its own without any medium, under electromagnetic wave gamma ray and radio wave comes. they are transverse wave.
This one is easy. It's just addition and subtraction. Add the partial pressure of Argon and the partial pressure of Helium:
152 kPa
<u>+305 kPa</u><u>
</u> 457 kPa
Next, subtract the result from the total pressure:
1015 kPa
<u>- 457 kPa</u>
558 kPa
H• •Be• •H --> H:Be:H
Since there are 4 valence electrons in total, Beryllium has 2 and Hydrogen has 2. You would put the Be in the middle because there is only 1 of them.
