Answer:
<h2>pH = 3.9</h2><h2>pOH = 10.1</h2>
Explanation:
Since is a weak acid to find the pH of we use the formula
where
Ka is the acid dissociation constant
c is the concentration
From the question
Ka of = 1.75 × 10^-5
c = 1.00 × 10-³M
Substitute the values into the above formula and solve for the pH
That's
We have the answer as
<h3>pH = 3.9</h3>
To find the pOH we use the formula
pH + pOH = 14
pOH = 14 - pH
pOH = 14 - 3.9
We have the answer as
<h3>pOH = 10.1</h3>
Hope this helps you
1.000.000 is the correct answer
Hello!
Your answer is A, asthenosphere
<u>The asthenosphere is a part of the mantle</u>. It helps move the plates in the Earth.
It is <u>below the lithosphere,</u> between <u>80 and 200 km</u> below the surface.
Therfore, the asthenosphere is <u>the part of the mantle that is still a solid but flows like a thick, heavy liquid.</u>
<u />
Hope this helps!
Have a great day!
Is a solid because liquids are not is not that close and gas is very far apart.
Answer:
The Bohr model suggested that electrons orbited the nucleus in circular paths where as the modern model views the atom to consist of positively charged nucleus surrounded by electrons.
Explanation:
In the modern model, the nucleus contains two sub-atomic particles, the protons which are positively charged and the neutrons which are not charged.According to Bohr's model,the electron in a hydrogen atom travel around the nucleus in a circular orbit. In the modern model, electrons do not move around nucleus around circular obits.
