Answer:
P = 0.75 atm
Explanation:
Using Boyle's law
Given ,
<u>For Bulb A</u>
Pressure = 190 torr
The conversion of P(torr) to P(atm) is shown below:
So,
Pressure = 190 / 760 atm = 0.25 atm
Volume = 200 mL
For Bulb B
Pressure = 1 atm
Volume = 400 mL
For Bulb C
Volume = 1.00 L = 1000 mL
Pressure = 75.994 kPa
The expression for the conversion of pressure in KiloPascal to pressure in atm is shown below:
P (kPa) = P (atm)
75.994 kPa = atm
Pressure = 0.75 atm
Also, Total volume, V = 200 + 400 + 1000 mL = 1600 mL
Using above equation as:
We get, Total pressure, P = 0.75 atm
B D and E. C isn't the answer because it is stopped.
The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth's total volume.
Answer:
D.)
Explanation:
The general equilibrium expression looks like this:
In this expression,
-----> K = equilibrium constant
-----> uppercase letters = formulas
-----> lowercase letters = balanced equation coefficients
In this case, all of the reactants and products are gases, so they should all be included in the expression. The products are in the numerator and the reactants are in the denominator. This makes the correct expression:
<----- Insert formulas
<----- Insert coefficients
