Autoionization Reactions are those reactions in which ions or molecules ionizes spontaneously without adding any external reagent.

For Example,
Autoionization of water.

H₂O + H₂O ⇆ H₃O⁺ + OH⁻

Autoionization reaction of Methanol is shown below,

STALIN [3.7K]

Answer:

Hi. Increased evaporation would be the greatest difference.

Explanation:

Have you ever had a drink in a mug with a lid? When you would remove the lid, all of the liquid on the lid is the liquid that would evaporate if there was no lid.

1. A helium-filled balloon had a volume of 8.50 L on the ground at 20.0°C and a

maw [93]

Answer:

133.74 L

Explanation:

First we convert the given pressures and temperatures into atm and K, respectively:

750.0 Torr ⇒ 750/760 = 0.9868 atm

20°C ⇒ 20+273.16 = 293.16 K

40°C ⇒ 40+273.16 = 313.16 K

Then we use the PV=nRT formula to calculate the number of moles of helium in the balloon, using the data of when it was on the ground:

0.9868 atm * 8.50 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 293.16 K

n = 2.866 mol

Then, knowing the value of n, we use PV=nRT once again, this time to calculate V using the data of when the balloon was high up:

0.550 atm * V = 2.866 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * 313.16 K

V = 133.74 L

Vinvika [58]

Answer:

$6.97 X 10^{-4}$ M

Explanation:

The concentration of the analyte in the 5-mL flask would be $6.97 X 10^{-4}$ M

This is a problem of simple dilution that can be solved using the dilution equation;

C1V1 = C2V2,

where C1 = initial concentration, V1 = initial volume, C2 = final concentration, and V2 = final volume.

In this case, the initial concentration (C1) is not known, the initial volume (V1) is 1.00 mL, the final concentration is 6.97 x 10-5 M, and the final volume is 10.00 mL.

Now, let us make the initial concentration the subject of the formula from the equation above;

C1 = C2V2/V1. Solve for C1 by substituting the other parameters.

C1 = 6.97 x 10-5 x 10/1 = $6.97 X 10^{-4}$ M
