Answer:
Explanation:
Henry's law states that the solubility of a gas is directly proportional to its partial pressure. The equation may be written as:
Where is Henry's law constant.
Our strategy will be to identify the Henry's law constant for oxygen given the initial conditions and then use it to find the solubility at different conditions.
Given initially:
Also, at sea level, we have an atmospheric pressure of:
Given mole fraction:
According to Dalton's law of partial pressures, the partial pressure of oxygen is equal to the product of its mole fraction and the total pressure:
Then the equation becomes:
Solve for :
Now we're given that at an altitude of 12,000 ft, the atmospheric pressure is now:
Apply Henry's law using the constant we found:
The given question is incomplete. The complete question is:
The combustion of propane (C3H8) in the presence of excess oxygen yields and
When only 2.5 mol of are consumed in order to complete the reaction, ________ mol of
are produced.
Answer: Thus when 2.5 mol of are consumed in their reaction, 1.5 mol of
are produced
Explanation:
The balanced chemical equation is:
According to stoichiometry :
5 moles of produce = 3 moles of
Thus 2.5 moles of will produce =
moles of
Thus when 2.5 mol of are consumed in their reaction, 1.5 mol of
are produced
