The classical bonding model which best explains the bonding in the compound NaH₂PO₄ is Hydrogen bonding.

<h3>What is Classical bonding model ?</h3>

By classical, we mean models that do not take into account the quantum behavior of small particles, notably the electron.

These models generally assume that electrons and ions behave as point charges which attract and repel according to the laws of electrostatics.

Sodium dihydrogen phosphate (NaH₂PO₄) is monoclinic, In which, the four independent hydrogen atoms were located on a difference map; they are involved in four O … O Hydrogen-bonds of length 2.654 (2), 2.589 (2), 2.559 (2), and 2.500 (2) Å.

The short contact (2.500 Å), which is not astride any symmetry element, is of the type O-H … O (asymmetrical).

The distorted coordination polyhedra of the sodium atoms are discussed in the light of recent theories on electrostatic balance.

Hence, the classical bonding model which best explains the bonding in the compound NaH₂PO₄ is Hydrogen bonding.

A 975 L balloon contains helium. On the ground the temperature is 30 0C and the pressure is 743 torr. What will be the balloon's
Archy [21]

Answer:

V₂ = 1518L

Explanation:

-Using combined gas law:

\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}

<em>Where P is pressure, V is volume and T is absolute temperature of 1, initial state and 2, final state of the gas.</em>

<em />

<em>Initial states:</em>

P₁ = 743 torr

V₁ = 975L

T₁ = 30°C + 273.15K = 303.15K

P₂ = 375 mmHg = torr

V₂ = Our incognite

T₂ = -35°C + 273.15K = 238.15K

Replacing:

\frac{743torr*975L}{303.15K} =\frac{375torrV_2}{238.15K}

<h3>V₂ = 1518L</h3>

A bond type with a difference in electro negativity of less than 0.4 would be classified as ...?
valina [46]

Answer:

Non polar covalent bond.

Explanation:

The covalent bond is polar when the electronegativity difference of bonded atom is greater than 0.4. If the electronegativity difference is 0.4 or less than this the bond will be non polar.

Covalent bond:

It is formed by the sharing of electron pair between bonded atoms.  

The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.

For example:

In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive and the bond is polar.

In case of F₂  the electronegativity difference is zero that's why the bond is non polar covalent bond.

Why is it difficult to detect the presence of isotopes of an element during chemical<br> studies?
slavikrds [6]

Answer:

Isotopes are atoms that have different number of neutrons, so they have a different mass number than the other atoms in an element.
