The answer is b. The sum of the individual gas pressure in the mixture
Answer:
Nurses must use organic chemistry to determine how the bodies of their patients metabolized glucose, and how the body reacts to it.
For this item, we need to assume that air behaves like that of an ideal gas. Ideal gases follow the ideal gas law which can be written as follow,
PV = nRT
where P is the pressure,
V is the volume,
n is the number of mols,
R is the universal gas constant, and
T is temperature
In this item, we are to determine first the number of moles, n. We derive the equation,
n = PV /RT
Substitute the given values,
n = (1 atm)(5 x 10³ L) / (0.0821 L.atm/mol.K)(0 + 273.15)
n = 223.08 mols
From the given molar mass, we calculate for the mass of air.
m = (223.08 mols)(28.98 g/mol) = 6464.9 g
<em>ANSWER: 6464.9 g</em>
Answer:
1 Ca(OH)2 + 2 HCl ---> 1 CaCl2 + 2 H2O
Dirt and a chair are examples if solids. Some more examples are tables chips and blankets.
