I just got it right in the test :)
If you had to find out the pressure at which a gas contained in a 3-liter container is 5 moles at 290K, what equation would you use?
Answer:
the ideal gas law equation
Explanation:
To solve this problem, I will simply apply the ideal gas law. The law is combination of Boyle's, Charles's and Avogadro's law.
Combining these laws gives;
PV = nRT
where P is the pressure
V is the volume
n is the number of moles
R is the gas constant
T is the temperature;
So;
P =
Using this equation we can find the Pressure.
Earth, water, air, and fire
Answer:
The answer is 6 valance electrons because it is oxygen and oxygen needs two more electrons to be a noble gas
