A strong acid has a stabilized conjugate base. Oxalic acid is stronger than malonic acid because its conjugate base has much more resonance structures than malonic acid's conjugate base.

Oxalic acid is stronger than malonic acid due to the presence of two carboxylic acid functional groups that can readily dissociate to release two protons, making it a stronger acid. Malonic acid has only one carboxylic acid group, so it can release only one proton, making it a weaker acid compared to oxalic acid.
Sulfuric acid is stronger than oxalic acid. Sulfuric acid is a strong mineral acid with a very low pH level, while oxalic acid is a weaker organic acid commonly found in vegetables like spinach and rhubarb.
This statement is incorrect. Acetic acid (CH3COOH) is weaker than oxalic acid (H2C2O4) based on their respective acid dissociation constants (Ka values). Acetic acid is a weak acid commonly found in vinegar, while oxalic acid is a stronger organic acid often used as a bleaching agent or in cleaning products.
Formic acid is stronger than acetic acid because it has a lower pKa value, indicating a stronger acidic nature. This is because formic acid can more readily donate a proton compared to acetic acid.
Formic acid and chloroacetic acid are stronger acids than acetic acid because they have a lower pKa value, which indicates a stronger tendency to donate a proton. This is attributed to the presence of electron-withdrawing groups in these acids that stabilize the conjugate base, enhancing their acidity.
