Can you explain these follow up questions using my answers to 1 and 2 1. Circle which of the following you would predict to be the strongest acid? Using yourunderstanding from Chapter 7, explain your reasoning.H₂OThe strongest acid is H2O because as we move along the period the acidity increases, theelectronegativity of the central atom increases which increases their acidity.a.2. For the acid-base reactions given, draw out the full reaction using Lewis structures andcurved arrows to indicate how the reaction takes place.Predict whether the equilibrium position would lie to the right or the left.
