Answer:

Explanation:

Using Charles Law ,

\frac{V1}{T1}=\frac{V2}{T2}

Using this formula we have ,

V1= 200cm^3

T1=40+273.15 = 313.15 K

T2 = 100+273.15 = 373.15 k

V2= ?

Hence using above formula simplify it we will get ,

V2 = 238.3 cm^3

Discuss the classical bonding model which best explains the bonding in the compound nah2po4
Ipatiy [6.2K]

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.

What is the morality of a solution made with 0.88 moles of KCl and 2.0 L of water?
Anarel [89]

Answer:

M=0.44M

Explanation:

Hello,

In this case, the molarity is defined as the ratio of the moles of the solute to the volume of the solution in liters:

M=\frac{n_{solute}}{V_{solution}}

In this case, the solute is the KCl (potassium chloride) and the solution is made up of both water and KCl. Moreover, since during this type of dissolution processes, the volume of the solution is not significantly affected by the addition of the solute, the resulting molarity is:

M=\frac{0.88mol}{2.0L}\\ \\M=0.44M

Best regards.
