Answer:
These systems are defined both by the types of energy and matter they contain and by how that matter and energy move through and between systems. In natural systems, both energy and matter are conserved within a system. This means that energy and matter can change forms but cannot be created or destroyed.
Explanation:
Answer:
The Partial pressure of Xe and Ne will be 4.95 atm and 1.55 atm. The number of moles of Xe and Ne will be 3.13 and 0.981
Explanation:
Let the total pressure of the vessel= 6.5 atm and mole fraction of Xenon= 0.761
As we know,
According to Dalton's Law of partial pressure-
Where,
The pressure of the gas component in the mixture
Mole fraction of that gas component
The total pressure of the mixture
<u>Calculation: </u>
To calculate the number of moles,
PV=nRT

To calculate atomic mass, you have to take to weighted average of the isotopes' masses. What that means is M = RA*106 + (1 – RA)*104, where RA is relative abundance expressed in decimal form. If you simplify the right side of that equation, you get M = 2*RA + 104. Doing a little more algebra yields RA = (M –104)/2 = (104.4 – 104)/2 = 0.4 / 2 = 0.2, which is 20%. So the answer is B.
Answer: Evaporation Condensation is used to seperate the parts of a mixture
Explanation: This is because it is the first order of the distilation process
Answer:
D. [NO₂]²/[N₂O₄]
Explanation:
The equilibrium constant expression for a reaction is products over reactants. Since NO₂ has a coefficient of 2, it will become an exponent.
So, it would be:
[NO₂]²/[N₂O₄]
Hope that helps.
