Given information:
Central atom = X
# lone pairs on X = 2
# bonds by X = 2 i.e 2 X-Y bonds.
The structure can be represented as Y-:X:-Y
It can be abbreviated as XY2Z2 where Z2 represents the two lone pairs on the central atom X.
Based on the electron geometry which accounts for the 2 two pairs and the 2 bonds, the central atom X would be sp3 hybridized with a tetrahedral geometry
From a molecular geometry perspective (which does not consider the lone pairs), the structure would be linear.
Answer:An endothermic reaction
Explanation: In an endothermic reaction, it takes more energy to break the bonds of the reactants than is released when the bonds in the products are formed. In an endothermic reaction, the temperature goes down.
average atomic mass of Cu = 63.54
Explanation:
average atomic mass = atomic mass of isotope 1 × abundance of isotope 1 + atomic mass of isotope 2 × abundance of isotope 2 +...+ atomic mass of isotope n × abundance of isotope n
average atomic mass of Cu = atomic mass of Cu-63 × abundance of isotope Cu-63 + atomic mass of isotope Cu-65 × abundance of isotope Cu-65
average atomic mass of Cu = 62.93 × (69.17 / 100) + 64.93 × (30.83 / 100)
average atomic mass of Cu = 63.54

<u>Answer:</u> The correct answer is Option A, Option B and Option D.
<u>Explanation:</u>
Molecular compound are defined as the compounds which are formed by the sharing of electrons between the atoms. They are also known as covalent compounds. They are of two types:
- <u>Polar covalent compound:</u> This compound is formed when difference in electronegativity between the atoms is present. When atoms of different elements combine, it results in the formation of polar covalent bond. For Example: etc..
- <u>Non-polar covalent compound:</u> This compound is formed when there is no difference in electronegativity between the atoms. When atoms of the same element combine, it results in the formation of non-polar covalent bond. For Example: etc..
We know that: Like dissolves like. This means that polar solvent will dissolve polar molecules and non-polar solvent will dissolve non-polar molecules
Water is a polar compound. So, it will dissolve only polar molecules.
The given substance 'X' is a molecular compound. It may be polar or non-polar.
So, it may be soluble in water or may not be soluble.
Electrolyte are defined as the compound which conduct electricity when dissolved in water. They conduct electricity because of the ions they dissociate into.
Thus, substance 'X' is not an electrolyte.
Hence, the correct answer is Option A, Option B and Option D.
