Whats the structure and bonding of sodium chloride

anastassius [24]

Sodium Chloride is ordinary table salt

You have a small sodium atom with a positive charge Na+, and a larger chlorine atom with a negative charge, making it a Chloride ion, Cl-.

This ion formation has resulted from Na transferring one of its electrons to Cl. there opposite charges then attract them to each-other.

Because the electrons are transferred rather than shared, we know that the bond is Ionic, rather than covalent.

Most ionic compounds, if not all, are salts that form a crystal lattice structure, due to the opposite charges in the molecule.

Think of it like this

Na+—Cl-
Cl—-Na+
Na+—Cl-

That’s how the molecules attract and stick to each other. That would continue until you ran out of NaCl molecules.

The molarity of a solution of 2.0 mol of NaOH in 5.OL of solution?

Gnesinka [82]

Answer:

Explanation:

The molarity of the NaOH solution can be found by using the formula

$c = \frac{n}{v} \\$

c is the molarity

n is the number of moles

v is the volume in L

From the question we have

$c = \frac{2}{5} = 0.4 \\$

We have the final answer as

Hope this helps you

Two objects of equal mass have a force of gravity of 6 N between them. Imagine the mass of one is cut in half and the other stay

Alenkasestr [34]

Answer:

F' = 3 N

Explanation:

Given that,

Two objects of equal mass have a force of gravity of 6 N between them.

If the mass of one is cut in half and the other stays the same such that,

m₁' = m₁ and m₂' = (m₂/2)

We need to find the new force. The gravitational force between two objects is given by :

$F=G\dfrac{m_1m_2}{r^2}$

We have, F = 6 N

New force,

$F'=G\dfrac{m_1'm_2'}{r^2}\\\\F'=\dfrac{Gm_1\times \dfrac{m_1}{2}}{r^2}\\\\=\dfrac{1}{2}\times \dfrac{Gm_1m_2}{r^2}\\\\F'=\dfrac{F}{2}\\\\F'=\dfrac{6}{2}\\\\F'=3\ N$

So, the new force becomes 3 N.
