Answer:
0.085 moles of oxygen needed to produce 0.085 moles of water.
Explanation:
Moles of water required to produce = 0.085 mol
According to reaction, 1 mole of water is obtained from 1 mole of oxygen gas, then 0.085 mole of water will be obtained:
of oxygen gas
0.085 moles of oxygen needed to produce 0.085 moles of water.

Answer:
296.43 K is the temperature of a vessel when pressure reads 1.250 atm.
Explanation:
At STP, when pressure is 1.000 atm the value of temperature is 273,15 K.
If the pressure at temperature T reads as 1.250 atm.
Applying Gay Lussac's law:
(At constant volume)
296.43 K is the temperature of a vessel when pressure reads 1.250 atm.
Answer: (B) The reverse reaction will proceed to establish equilibrium.
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.
This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
For the given equation:
Given : when is added to the system
If the concentration of that is the product is increased, so according to the Le-Chatlier's principle, the equilibrium will shift in the direction where decrease of concentration of
takes place. Therefore, the equilibrium will shift in the left or backward direction.
Thus the reaction will shift towards reactants to reestablish equilibrium and thus partial pressure of and
decreases and the partial pressure of
increases.
