gas
The usual state of oxygen and hydrogen: they are gases at room temperature.
This solubility is 8 mg/L.
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.
298 K is the standard room temperature, while 273.15 K is the standard temperature for converting Celsius to Kelvin.
It is not spontaneous.
At 101.3 kPa and 298 K, the element present is likely to be oxygen (O2) due to its high natural abundance in the atmosphere and its physical properties at that temperature and pressure.
The usual state of oxygen and hydrogen: they are gases at room temperature.
Carbon dioxide (CO2) is formed from its elements (carbon and oxygen) by an exothermic reaction at 298 K and 101.3 kPa.
This solubility is 8 mg/L.
298 degrees Fahrenheit = 420.93 K.
The state of nitrogen is gas at 298 K. Nitrogen's symbol is N and it;s atomic number is 7.
At normal room temperature of 298 K, sulphur is a solid. 388.36 K is enough to melt it, while 717.8 K is enough to boil it. The vapour-liquid critical point is at 1314 K and 20.7 MPa.
The state of sulfur is solid at 298 K. Sulfur's symbol is S and its atomic number is 16.
The value of Kw (ion product of water) at 298 K is approximately 1.00 x 10^-14.

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.
The electron configuration of 1s22s22p3s1 is not the ground state electron configuration of any element. This configuration contains 8 electrons, which in the ground state would be oxygen. The ground state configuration of oxygen is 1s22s22p4.
