Answer:
5.66g/ml
Explanation:
Mass of Metal Slug, m = 25.17g
Volume of container (flask), v = 59.7ml
Mass of Methanol, M = 43.7g with density, d = 0.791g/ml
Therefore,
Volume of Methanol = M/d = 43.7 / 0.791 = 55.25ml
Volume of Metal slug in the flask = v - V = 59.7 - 55.25 = 4.45ml
Density of Metal slug = mass of metal slug / volume of metal slug
= 25.17 / 4.45 = 5.66g/ml
Explanation:
Let us assume that the given data is as follows.
mass of barium acetate = 2.19 g
volume = 150 ml = 0.150 L (as 1 L = 1000 ml)
concentration of the aqueous solution = 0.10 M
Therefore, the reaction equation will be as follows.

Hence, moles of
=
.......... (1)
As, No. of moles =
Hence, moles of
will be calculated as follows.
No. of moles =
=
(molar mass of
is 255.415 g/mol)
= 
Moles of
= 
= 0.01715 mol
Hence, final molarity will be as follows.
Molarity = 
= 
= 0.114 M
Thus, we can conclude that final molarity of barium cation in the solution is 0.114 M.
A reaction in which bonds are created is usually associated with the Release of energy.
What are the various types of bonds?
There are three sorts of bonds:
1. Electrovalent or electrovalent bond
2. chemical bond
3. dative bond
Electrovalent or electrovalent bond are formed when one or more electrons are transferred from one atom to another.
Covalent bonds are formed when the atoms during a molecule share an equal number of electrons.
A dative bond is one in which both electrons in a shared pair come from the same atom.
Now, atoms tend to stabilize once they form chemical bonds, releasing energy within the process. Energy is released because there's a higher level of stability associated with a low energy level.
Hence, a reaction in which bonds are created is usually associated with the release of energy.

Answer:
coordination number
Explanation:
Coordination number -
In a crystal lattice , the number of atoms that are surrounded to a particular atom , is referred to as the coordination number of the crystal.
In the field of crystallography and chemistry , it is also called the ligancy.
In coordination chemistry , the number of ligands attached to the central metal atom is also known as the coordination number of the coordination compound.
Hence, from the given statement of the question,
The correct term is coordination number.
