A better explanation of these systems is given using molecular orbital theory.
<h3>What is the valence bond theory?</h3>
The valence bond theory hold that a bond is formed by the sharing of two electron in a covalent bond. This bond does not account for certain systems that occur in multiple bonded systems where the simple two electron bonding model does not suffice.
Thus, valence bond theory is inadequate for describing systems with multiple adjacent bonds that overlap, as in aromatic molecules. a better explanation of these systems is given using molecular orbital theory.

Answer:
B. 0.174
Explanation:
A buffer is formed by a weak acid (CH₃COOH) and its conjugate base (CH₃COO⁻, coming from sodium acetate). We can calculate the pH of this buffer using the Henderson-Hasselbalch equation.
pH = pKa + log [CH₃COO⁻]/[CH₃COOH]
pH - pKa = log [CH₃COO⁻]/[CH₃COOH]
3.98 - (-log 1.80 × 10⁻⁵) = log [CH₃COO⁻]/[CH₃COOH]
-0.760 = log [CH₃COO⁻]/[CH₃COOH]
[CH₃COO⁻]/[CH₃COOH] = anti log (-0.760)
[CH₃COO⁻]/[CH₃COOH] = 0.174
The amount of 4.86 ml needed to completely react with 11.73 ml of 1.006 m ca(oh)2 is 4.86 ml.
given data to be calculated:-
Ca3(PO4)2 (s) + 6H2O can be used to calculate this: 3Ca(OH)2 (aq) + 2H3PO4 (aq) (l)
ca moles (OH)
2 present 11.00 moles of H3PO4 are required; 7.33 moles of H3PO4 in a volume of ml are required; 7.33/1.508 = 4.86.
<h3>How do moles react to an increase in volume?</h3>
The direction that creates more moles of gas benefits from an increase in volume, and since there are more moles of products in this case, the reaction will shift to the right and produce more moles of products.
