Answer: hydrogen and oxygen
Explanation:
Sulfuric acid is considered as a Bronsted acid because it is a proton donor. When in solution, the molecules of the compound dissociates into ions, the hydrogen ion and the the sulfate ion. It donates the hydrogen ion so it is an acid, a bronsted acid.
Use the van der Waals equation and the ideal gas equation to calculate the volume of 1.000 mol of neon at a pressure of 500.0 atm and a temperature of 355.0 K.
The Van der Waals equation, also known as the Van der Waals equation of state, is an equation of state used in chemistry and thermodynamics that extends the ideal gas law to take into account the effects of molecular interaction as well as the finite size of the molecules in a gas.
We may build a new equation that better reflects real gas behavior by modifying the ideal gas law to include corrections for interparticle attractions and particle volumes. The van der Waals equation can be used to determine a gas's properties under less-than-ideal circumstances.

Answer:
160.9 mol ≅ 161.0 mol.
Explanation:
- It is known that every 1.0 mole of compound or element contains Avogadro's number (6.022 x 10²³) of molecules or atoms (formula units).
Using cross multiplication:
1.0 mole of Fe(NO₃)₃ contains → 6.022 x 10²³ formula units.
??? mole of Fe(NO₃)₃ contains → 9.69 x 10²⁵ formula units.
<em>∴ The no. of moles of He contains (9.69 x 10²⁵ formula units)</em> = (1.0 mol)(9.69 x 10²⁵ formula units.)/(6.022 x 10²³ formula units) = <em>160.9 mol ≅ 161.0 mol.</em>
