Baking soda is a pure substance, sodium bicarbonate. Vinegar is a mixture of acetic acid dissolved in water, and it is only the acetic acid that reacts. Acetic acid and sodium bicarbonate can react together according to the chemical equation below: HC2H302 NaHCOe NAC2H302 + H20 + CO2 acetic acid + sodium bicarbonate sodium acetate + water + carbon dioxide Samuel wants to help his brother make a science fair volcano. 1. For his first experiment, Samuel obtains samples of solid acetic acid powder and solid sodium bicarbonate powder from his chemistry teacher. He mixes the two powders together, but there is no reaction. b) Considering the state of matter of the particles, give a possible explanation for why there is no reaction.
