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.
Physical properties are characteristics that describe matter. They include characteristics such as size, shape, color, and mass. These characteristics can be observed or measured without changing the identity of the matter in question.
4Li + O₂ = 2Li₂O
Li : Li₂O = 4 : 2 = 2 : 1
2 : 1
x : 4
x=4*2/1=8 mol
D) 8
The two control bases would be water and salt.
