What are the concentrations of hydroxide and hydronium ions in a solution with a pH of 8.3?

Chemistry

Margarita [4]3 years ago
5 0

Answer:

The hydroxide concentration is 2*10^-6 M

The hydronium concentration is 5*10^-9 M

Explanation:

Step 1: Data given

pH = 8.3

Step 2: Calculate [H+]

pH = 8.3 = -log [H+]

[H+] = 10^-8.3 = 5*10^-9 M

[H+] = [H3O+] = 5*10^-9 M

Step 3: Calculate pOH

pH + pOH = 14

pOH = 14 -pH = 14 - 8.3 = 5.7

Step 4: Calculate concentration of hydroxide

pOH = -log [OH-] = 5.7

[OH-] = 10^-5.7 = 2*10^-6 M

The hydroxide concentration is 2*10^-6 M

The hydronium concentration is 5*10^-9 M

what is the maximum amount of moles of P2O5 that can theoretically be made from 136 g of P4 and excess oxygen
zhuklara [117]
We are given with
136 g P4
excess oxygen

The complete combustion reaction is
P4 + 5O2 => 2P2O5
Converting the amount of P4 to moles
136/123.9 = 1.098 moles

Using stoichiometry
moles P2O5 = 1.098 x 2 = 2.195 moles P2O5

Jennie observes her brother playing pool and has a theory that the potential energy in the pool stick is transformed into kineti
Shkiper50 [21]

A lot of theories exist in the world today regarding energy. The statement that explains how she can prove her theory is below:

  • He could measure the potential energy when the pool stick is pulled back before moving to strike the pool ball, and she could measure the kinetic energy of the ball in motion after the pool stick strikes it. There should be an equal amount of kinetic energy and potential energy to prove there was a transformation of potential energy to kinetic energy.

Potential energy is known to be of position relative, and kinetic energy is motion relative.

The relationship that exist between the two is their ability to transform into one another. That is potential energy transforms into kinetic energy, and kinetic energy converts into potential energy, and vice versa

If an outside force acts upon an object with potential energy, that force is said to change the potential energy into kinetic energy.

The full question is below

Jennie observes her brother playing pool and has a theory that the potential energy in the pool stick is transformed into kinetic energy when he hits the ball.

Which explains how she can prove her theory?

A

She could measure the potential energy in the motionless ball on the pool table, and she could measure the potential energy of the pool stick as it moves to strike the ball. These total of these two measurements will be equal to the kinetic energy in the pool ball as it moves, and this proves there was a transformation of energy.

B

She could measure the potential energy when the pool stick is pulled back to strike the pool ball, and then she could measure the kinetic energy in the pool stick as it moves to strike the ball. The potential energy in the pool stick and the kinetic energy in the pool stick should be equal, proving there was a transformation of energy.

C

She could measure the potential energy when the pool stick is pulled back before moving to strike the pool ball, and she could measure the kinetic energy of the ball in motion after the pool stick strikes it. There should be an equal amount of kinetic energy and potential energy to prove there was a transformation of potential energy to kinetic energy.

D

She could measure the potential energy of the pool ball when it was sitting on the table, and she could measure the kinetic energy of the ball in motion after the pool stick strikes it. There should be an equal amount of potential energy in the motionless ball and kinetic energy in the ball after the stick strikes it to prove there was a transformation of potential energy to kinetic energy.:
