AgNO3 ( aq ) + NaI ( aq ) = NaNO3 ( aq ) + AgI ( s ) .
Answer: The partial pressure of
is 0.35 atm.
Explanation:
Given: Total pressure = 0.98 atm
Partial pressure of
= 0.48 atm
Partial pressure of Ar = 0.15 atm
Partial pressure of
= ?
Total pressure is the sum of partial pressure of each component present in a mixture of gases.
Hence, partial pressure of
is calculated as follows.
Total pressure = ![P_{N_{2}O} + P_{O_{2}} + P_{Ar}](https://tex.z-dn.net/?f=P_%7BN_%7B2%7DO%7D%20%2B%20P_%7BO_%7B2%7D%7D%20%2B%20P_%7BAr%7D)
Substitute the values into above formula as follows.
![Total pressure = P_{N_{2}O} + P_{O_{2}} + P_{Ar}\\0.98 atm = P_{N_{2}O} + 0.48 atm + 0.15 atm\\P_{N_{2}O} = 0.35 atm](https://tex.z-dn.net/?f=Total%20pressure%20%3D%20P_%7BN_%7B2%7DO%7D%20%2B%20P_%7BO_%7B2%7D%7D%20%2B%20P_%7BAr%7D%5C%5C0.98%20atm%20%3D%20P_%7BN_%7B2%7DO%7D%20%2B%200.48%20atm%20%2B%200.15%20atm%5C%5CP_%7BN_%7B2%7DO%7D%20%3D%200.35%20atm)
Thus, we can conclude that the partial pressure of
is 0.35 atm.
Element X is sodium.
If there is one more shell of electrons, then this means it is one period below.
Since there is one less valence electron, it is one group to the left.
Answer: repelling magnets
Explanation:
The Maglev track allows the train to float above the track through the use of repelling magnets. ... This change in polarity causes the magnetic field in front of the train to pull the vehicle forward, while the magnetic field behind the train adds more forward thrust
