Benzoic acid has a chemical formula $C_{7} H_{6} O_{2}$ while salicylic acid has the chemical formula $C_{7} H_{6} O_{3}$ . From the chemical formula alone, the differences between benzoic acid and salicylic acid is already evident as the latter has an extra oxygen in its chemical formula.

Structurally speaking, both of them are carboxylic acids with the benzene ring as the base. However, salicylic acid has an additional hydroxyl group (-OH) connected to the carbon immediately next to the carbon connected to the acidic (-COOH) group.

The structures for benzoic acid and for salicylic acid, respectively, are shown in the figures below.

krok68 [10]

I think the correct term to fill in the blank would be equal. According to the law of conservation of mass, when sodium, hydrogen, and oxygen react to form a compound, the mass of the compound is equal the sum of the masses of the individual elements. This particular states that the mass cannot be created nor destroyed. So, for every process, the total inflow of mass should be the same total mass for the outflow since mass should be constant all through out. So, for a reaction, the total mass of the reactants should be equal to the total mass of the products.
