Answer:
Explanation:
The gas ideal law is
PV= nRT (equation 1)
Where:
P = pressure
R = gas constant
T = temperature
n= moles of substance
V = volume
Working with equation 1 we can get
![n =\frac{PV}{RT}](https://tex.z-dn.net/?f=n%20%3D%5Cfrac%7BPV%7D%7BRT%7D)
The number of moles is mass (m) / molecular weight (mw). Replacing this value in the equation we get.
or
(equation 2)
The cylindrical container has a constant pressure p
The volume is the volume of a cylinder this is
![V =(pi)*r^{2}*h](https://tex.z-dn.net/?f=V%20%3D%28pi%29%2Ar%5E%7B2%7D%2Ah)
Where:
r = radius
h = height
(pi) = number pi (3.1415)
This cylinder has a radius, r and height, h so the volume is ![V =(pi)*r^{2}*h](https://tex.z-dn.net/?f=V%20%3D%28pi%29%2Ar%5E%7B2%7D%2Ah)
Since the temperatures has linear distribution, we can say that the temperature in the cylinder is the average between the temperature in the top and in the bottom of the cylinder. This is:
Replacing these values in the equation 2 we get:
(equation 2)
it is more dense think about how heavy the water feels you go down you feel more pressure so it is denser
Your answer is :
P = K * x where P is partial pressure K is Henry's constant and x is solubility
<span>775 torr = K L·torr/mol * 0.0.0347 mole / liter </span>
<span>K = 775 / 0.0347 = 22334 L·torr/mol </span>
<span>in the second solution we have </span>
<span>1670 = 22334 * x </span>
<span>x = 1670 / 22334 </span>
<span>= 0.075 moles CO2 per liter of water.

Answer:
Explanation:Calculate the Energy Needed to Change a Solid Into a Liquid ... Heat of fusion is the amount of heat energy required to change the state of matter ... of fusion is: q = m·ΔHf; Note that the temperature does not actually change when ... Useful information: Heat of fusion of water = 334 J/g = 80 cal/g ... m = mass
A solution with hydroxide ion concentration of 4.15 x10^-6 m is basic and has a hydrogen ion concentration of 2.41 x10^-9 M
we well know thaat (H^+) (OH^-) = 1 x10^-14
by making H^+ concentration the subject of the formula
H^+ = 1 x10^-14/OH^-
H^+= 1 x10^-14/4.15 x10^-6 = 2.41 x10^-9 M
the solution is basic since OH^- ion is for basic solution
