What is standard state of oxygen in enthalpy of formation?
The usual state of oxygen and hydrogen: they are gases at room temperature.
What is the solubility of oxygen in water exposed to air at 1 ATM and 298 K?
This solubility is 8 mg/L.
What is the pressure in atmospheres exerted by a 0.500 mol sample of oxygen gas in a 10.0 L container at 298 K?
To find the pressure exerted by the gas, we can use the ideal gas law, ( PV = nRT ). Here, ( n = 0.500 ) mol, ( R = 0.0821 , \text{L} \cdot \text{atm} / (\text{mol} \cdot \text{K}) ), and ( T = 298 , \text{K} ). Plugging in the values, we get ( P = \frac{nRT}{V} = \frac{0.500 \times 0.0821 \times 298}{10.0} \approx 1.22 ) atm.

What is the velocity of hydrogen at 298 K?
The average velocity of hydrogen molecules at 298 K can be calculated using the root mean square velocity formula, v = √(3kT/m), where k is the Boltzmann constant, T is the temperature in Kelvin, and m is the mass of a hydrogen molecule. The average velocity of hydrogen at 298 K would be around 1926 m/s.
