Answer:

2.5x10^-14

Explanation:

Use the pH/pOH square to get around

pH to H+ is 10^-pH so 10^-13.6

Suppose 0.035 moles of HCl is dissolved in enough water to produce 750 mL of solution. What is the pH
zhuklara [117]

Answer:

pH = 1.33

Explanation:

Because HCl is a strong acid, each mole of HCl will completely dissociate into H⁺ and Cl⁻ species.

Now we calculate the molar concentration (molarity) of H⁺:

  • Molarity = moles / volume

(750 mL ⇒ 750 / 1000 = 0.750 L)

  • Molarity = 0.035 moles / 0.750 L
  • Molarity = 0.0467 M

Then we calculate the pH of the solution:

  • pH = -log [H⁺]
  • pH = -log (0.0467 M)
  • pH = 1.33

Calculate the ratio of the velocity of helium atoms to the velocity of neon atoms at the same temperature.
o-na [289]

Answer:

vHe / vNe = 2.24

Explanation:

To obtain the velocity of an ideal gas you must use the formula:

v = √3RT / √M

Where R is gas constant (8.314 kgm²/s²molK); T is temperature and M is molar mass of the gas (4x10⁻³kg/mol for helium and 20,18x10⁻³ kg/mol for neon). Thus:

vHe = √3×8.314 kgm²/s²molK×T / √4x10⁻³kg/mol

vNe = √3×8.314 kgm²/s²molK×T / √20.18x10⁻³kg/mol

The ratio is:

vHe / vNe = √3×8.314 kgm²/s²molK×T / √4x10⁻³kg/mol / √3×8.314 kgm²/s²molK×T / √20.18x10⁻³kg/mol

vHe / vNe = √20.18x10⁻³kg/mol / √4x10⁻³kg/mol

<em>vHe / vNe = 2.24</em>

<em />

I hope it helps!
