The number of electrons involved when two atoms in a molecule are connected by a “triple bond” is to be stated and the Lewis structure of the molecule containing double bond is to be drawn. Concept Introduction: The bond formed when electrons are being shared by the atoms is called covalent bond. The bond involving two valence electrons is known as single bond. The bond involving four valence electrons is known as double bond. The bond involving six valence electrons is known as triple bond. The representation of an element along with its valence electrons is referred to as Lewis symbol or Electron Dot Symbol. The electrons which are present in valence shell are represented by dots around the symbol of an element. The Lewis structure exhibits the connection between atoms.

Using the conditions of spontaneity to deduce the signs of AH and AS
Use the observations about each chemical reaction in the table below to decide the sign (positive or negative) of the reaction enthalpy AH and reaction entropy
AS.
Note: if you have not been given enough information to decide a sign, select the "unknown" option.

A chemist titrates 70.0 mL of a 0.7089 M hydrocyanic acid (HCN) solution with 0.4574M KOH solution at 25 °C. Calculate the pH at equivalence. The pK of
hydrocyanic acid is 9.21.
Round your answer to 2 decimal places.
Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of KOH solution added.
