Answer:
D
Explanation:
Its the only answer that actually makes sense and i got it right on the quiz.
Answer: The molar mass of A is one fourth that of B
Explanation:
To calculate the rate of diffusion of gas, we use Graham's Law.
This law states that the rate of diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows the equation:
So,
We are given:
Rate of diffusion of A = 
Rate of diffusion of B
Putting values in above equation, we get:
Thus the molar mass of A is one fourth that of B
Answer:
0.1575 atm
Explanation:
we have that equilibrium constant Kp = (PNO)₂PO₂ / (PNO₂)₂
and it is given to be 158
==> Kp = (PNO)₂PO₂ / (PNO₂)₂ = 158
we also have that the partial pressure of O2 (PO₂) = 0.99 atm
Therefore,
PO₂ = 0.99 atm ==> PNO = 2(0.99 atm) = 1.98 atm (based on the stoichiometry)
==> PNO₂ = √((PNO)₂PO₂ / 158) atm = √((1.98)*2(0.99) / 158) atm = 0.1575 atm
Answer:
110.30 grams
You have to multiply by 8.96.
12.31 x 8.96 = 110.30 grams.
Therefore, that is your answer.
(Sorry I had to answer twice it was because of LukeG1).
Answer: Water
Explanation: I don't see any graph attached, but water has a boiling point of 100C, which is where it would become gas, or water vapor. 0C is the freezing point of water, where it would become ice. Since 50C is in the middle, it would be considered liquid.
