I will chill a container so that its outer surface is very cold, but dry. Then I will
wave the container through the air, and point out the liquid water from the air
that collects on the cold outer surface of the container.
Answer:
it doesnt even give you enough information for you to answer it
Explanation:
Answer:
francium, caesium, helium
Iodine has 7 valence electrons. It needs therefore only 1 electron to be stable this is why it is so reactive.
Answer:
76 mmHg is the partial pressure of oxygen on this new planet.
Explanation:
Atmospheric pressure on air on earth = 760 mmHg
On an unknown planet :
Oxygen makes up 10% of the atmosphere.
The mole fraction of oxygen gas can be written as = 
Carbon dioxide makes up 15% of the atmosphere.
The mole fraction of carbon dioxide gas can be written as = 
Nitrogen makes up the remaining 75% of the atmosphere.
The mole fraction of nitrogen gas can be written as = 
Atmospheric pressure of air on unknown planet,p= 760 mmHg (given)
Partial pressure of gases can be calculated by the help o Dalton's law of partial pressure:
Partial pressure of oxygen gas :


Partial pressure of carbon dioxide gas :


Partial pressure of nitrogen gas :
