Answer:
1.27 atm is the final pressure of the oxygen in the flask (with the stopcock closed).
2.6592 grams of oxygen remain in the flask.
Explanation:
Volume of the flask remains constant = V = 2.0 L
Initial pressure of the oxygen gas =
Initial temperature of the oxygen gas =
Final pressure of the oxygen gas =
Final temperature of the oxygen gas =
Using Gay Lussac's law:
1.27 atm is the final pressure of the oxygen in the flask (with the stopcock closed).
Moles of oxygen gas = n
(ideal gas equation)
Mass of 0.08310 moles of oxygen gas:
0.08310 mol × 32 g/mol = 2.6592 g
2.6592 grams of oxygen remain in the flask.

Answer:
(K) = [H2] [Cl2] / [HCl]²
Explanation:
The equation of the reaction is given as;
2 HCl (g) ⇔ H2 (g) + Cl2 (g)
The Equilibrium constant is the ratio of the concentration of the products and reactants raised to the power of their coefficients
Products = H2 and Cl2
Reactants = HCl
Equilibrium constant (K) = [H2] [Cl2] / [HCl]²
Convection is the transfer of heat/thermal enrgy by the movement of a fluid(either a liquid or gas).
