When compared to sulfuric acid, how strong are carboxylic acids?

Carboxylic acids are weaker than sulphuric acids, the Ka or the acid ionization constant measured for this is less than 1, indicating that the reaction will proceed in both the forward and reverse directions.

The answer is a) carbon-12

Both models are effective because they show the valence electrons, and these valence electrons indicate the reactivity of an element.
