Answer:
D. 1x10⁻¹¹ M
Explanation:
For any given aqueous solution the<em> following formula</em> is true:
1x10⁻¹⁴ = [H₃O⁺] * [OH⁻]
1x10⁻¹⁴ is the ion-product constant of water, <em>Kw</em>.
We <u>input the given value of [H₃O⁺]</u>:
1x10⁻¹⁴ = 1x10⁻³ * [OH⁻]
And <u>solve for [OH⁻]</u>:
[OH⁻] = 1x10⁻¹¹ M
Thus the correct answer is option D. 1x10⁻¹¹ M.
Answer:
At the plate boundary, there would be a divergent boundary where we can see a mid ocean ridge and a gap. We would be able to see the mantle because there would be a fissure from where magma will rise and solidify.
Explanation:
Under the South American plate and African plate, there are currents that cause a divergent boundary. They create this boundary since they pull the tectonic plates apart, causing a mid-ocean ridge with an opening that allows the rising of the magma that was underneath. Once that the magma is out, it solidifies, and the currents will try to create another ridge to repeat the process.
When the plates are apart, the mantle that is beneath is exposed, and we can see the magma.
Newton's third law of interaction, says that if one body exerts a force on a second body, the second body exerts a force equal in magnitude and opposite in direction on the first body. It's the law of action-reaction, and it helps to explain why you feel a jolt when you collide with another bumper car.
