AgNO3 + Cu = Cu(NO3)2 + 2Ag .. this is an example of a single replacement reaction.
Answer:
The partial pressure of the 
in the final mixture is 200 kPa.
Explanation:
Pressure of nitrogen gas when the two tanks are disconnected = 500 kPa
Pressure of the carbon-dioxide gas when the two tanks are disconnected = 200 kPa
Moles of nitrogen gas =
Moles of carbon dioxide gas =
After connecting both the tanks:
The total pressure of the both gasses in the tank = p = 250 kPa
According to Dalton' law of partial pressure:
Total pressure is equal to sum of partial pressures of all the gases
Partial pressure of nitrogen =
Partial pressure of carbon dioxide=
The partial pressure of the in the final mixture is 200 kPa.
The water cycle is a cycle that makes water go in the sky and back on ground again. It has 3 main processes which are Condensation: water droplets collect on a cold surface and combine with humid air, Evaporation: the process of a liquid turning into a gas, and Precipitation: The process of water falling from the sky like; rain, snow, sleet, and hail.
<span>Technically, this question is badly worded. If all 4 containers were at STP, then all 4 containers would have the same pressure. So I'll assume instead that all 4 containers are at the same temperature, and then use the ideal gas law to determine the relative internal pressures of each container.
The idea gas law is
PV = nRT
where
P = Pressure
V = Volume
n = number of moles
R = Ideal gas constant
T = Absolute temperature
Since all the containers are at the same temperature, we can ignore the R and T parts of the formula and substitute some value K for constant. So we get
PV = nK
Now solve for P
PV = nK
P = nK/V
From the above, you can see that the pressure is proportional to the number of moles divided by the volume. So let's calculate that value for each container.
Container A: 0.5 / 11.2 = 0.044642857
Container B: 2 / 22.4 = 0.089285714
Container C: 1 / 22.4 = 0.044642857
Container D: 2 / 11.2 = 0.178571429
So as you can see, the pressures in containers A and C are the same, which is the first available option, so you are correct.</span>
