Answer:

The answer is b: It is the sharing of electrons by overlapping orbitals

Explanation:

The ionic bong involves the exchange of electrons from one atom to another to keep eight particles in their outermost orbit. In this way the atoms become stable.  This happens between a metal, which losing electrons becomes a cation that now has a positive charge, and a non-metal, which accepting electrons becomes an anion that now has a negative charge. So the ionic bond is the electrostatic attraction between oppositely charged particle (cation and anion).

No chemical bond involves sharing neutrons between two nuclei. Chemical bonds occur between the electrons of atoms, which are found in the outer layer around the nuclei.

So, the correct answer is b: It is the sharing of electrons by overlapping orbitals.  This happens between two non-metallic elements.

Why is a mass movement of mud called a flow?
wariber [46]
In terms of a deeper scientific reason, I am not sure, but the basic reason is quite simple. "Mud" tends to look like a mix between a solid, dirt, and a liquid, water or some other liquid. Since it is, in fact, a cross between a solid and a liquid, it has properties of both. It has certain physical and visual properties that only a solid would have, such as texture and opaqueness, but it also has physical properties of a liquid. Since it leans more towards the liquid side than the solid side, we say mud "flows" rather than saying that it "rolls" or "bounces".

You have 26.7 mL of 0.061 mol/L aqueous potassium hydroxide (KOH(aq)) in a conical flask. In a burette
Natasha2012 [34]

Answer:

9.47 mL

Explanation:

The reaction that takes place is:

  • 2KOH + H₂SO₄ → K₂SO₄ + 2H₂O

First we <u>calculate how many KOH moles reacted</u>, using <em>the given concentration and volume of KOH solution</em>:

  • 0.061 mol/L = 0.061 mmol/mL
  • 0.061 mmol/mL * 26.7 mL = 1.6287 mmol KOH

Then we <u>convert KOH moles into H₂SO₄ moles</u>, using the <em>stoichiometric coefficients</em>:

  • 1.6287 mmol KOH * \frac{1mmolH_2SO_4}{2mmolKOH} = 0.8144 mmol H₂SO₄

Finally we <u>calculate the required volume of the H₂SO₄ solution</u>, using<em> the number of moles and given concentration</em>:

  • 0.8144 mmol ÷ 0.086 mmol/mL = 9.47 mL
