I believe the answer is thermal expansion.
Answer:
The concentration of the Cu²⁺ solution in the 10,0 mL volumetric flask is 5,425×10⁻³ M Cu²⁺
Explanation:
The first dilution from a 2,17M Cu²⁺ solution gives:
2,17 M Cu²⁺ ×
= <em>0,0217 M Cu²⁺solution</em>
<em />
The second dilution gives as concentration:
0,0217 M Cu²⁺ ×
= 5,425×10⁻³ M Cu²⁺ solution
I hope it helps!
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.
