Answer:
a. S = 2.41 x 10⁻⁴ M
Explanation:
The solubility S of a gas in water at a given temperature is given by the equation
S = Kp where S= solubility of the gas
K= Henry's Constant for the gas
p = partial pressure of the gas
solving for S
S = 3.70 x 10⁻⁴ M/atm x 0.650 atm =2.41 x 10⁻⁴ M
Answer:
The line with spikes and semicircles is a stationary front, it brings days of steady rain.
Explanation:
L means Low pressure, it brings stormy weather with strong winds.
H means High pressure, it brings fair weather and light winds.
The line with spikes is a cold weather front, it brings thunderstorms and colder
temperatures.
The line with spikes and semicircles is a stationary front, it brings days of steady rain.
The atomic weight of H is 1, O is 16.
There are two of each in a hydrogen peroxide molecule.
(1*2)+(16*2)=2+32
2+32=34
The weight of the whole molecule is 34, and hydrogen makes up 2 of that.
(2/34)*100=0.0588235294*100
0.0588235294*100=5.88235294
The percentage mass of hydrogen in a hydrogen peroxide molecule is 5.88%
