Classify each of the following as a Strong acid (sa) or a Weak acid (wa) and indicate how each should be written in aqueous solution. Classify ... In solution this acid should be written as: fill in the blank 1 1. nitric acid fill in the blank 3 2. perchloric acid fill in the blank 5 3. hydrofluoric acid

1. nitric acid: sa

2. perchloric acid: sa

3. hydrofluoric acid: wa

Explanation:

A strong acid (sa) is the one that is completely dissociated into ions in water. Conversely, a weak acid (wa) is not completely dissociated in water.

From the options, the strong acids are:

1. nitric acid (HNO₃). It dissociates completely into ions when is dissolved in water, as follows:

HNO₃ → H⁺ + NO₃⁻

2. perchloric acid (HClO₄). It is completely dissociated in water as follows:

HClO₄ → H⁺ + ClO₄⁻

The weak acid is hydrofluoric acid (HF). In water, only a small proportion is dissociated into ions. The proportion of ions formed is given by the equilibrium constant Ka. The dissociation is written by using double arrows:

HF ⇄ H⁺ + F⁻

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
