Answer:
diffusion
Explanation:
Diffusion can be defined as the net movement of particles from a high concentration to a low concentration. This sounds like the most plausible word in this case.
Answer: adding
Explanation:
Because it takes thermal energy to power it
You did not provide the statement, however, the most accurate things about atoms is that everything is made out of them in the entire universe, and they consist of protons, electrons, and neutrons. They create all substances in existence.
<h3>Answer:</h3>
[OH⁻] = 1.0 × 10⁻¹⁰ M
<h3>Solution:</h3>
In order to calculate concentration of hydroxide ion i.e. [OH⁻] first we will find the pOH by using following relation,
pH + pOH = 14
Putting value of pH given and solving for pOH,
4.0 + pOH = 14
pOH = 14 - 4.0
pOH = 10.0
As ,
pOH = -log [OH⁻]
So,
[OH⁻] = 10^-pOH
Putting value of pOH,
[OH⁻] = 10⁻¹⁰
[OH⁻] = 1.0 × 10⁻¹⁰ M
